I have an Iphone application in which i am combining two arrays and displaying in the same table.the problem here is i was not able to change the position of the detailed textlabel in the cell.here is my code snippet `
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
UIImageView* img = [[UIImageView alloc]initWithImage:[UIImage imageNamed:#"cell_with_arrow.png"]];
[cell setBackgroundView:img];
[img release];
}
if(newssarray==nil||[newssarray count]==0)
{
}
else
{
NSDictionary *dicttable=[newssarray objectAtIndex:indexPath.row];
head=[dicttable objectForKey:#"news"];
head1=[dicttable objectForKey:#"name"];
NSString *sub=[dicttable objectForKey:#"created"];
NSLog (#"%#",head);
[[cell viewWithTag:12] removeFromSuperview];
[[cell viewWithTag:13] removeFromSuperview];
[[cell viewWithTag:14] removeFromSuperview];
UIButton *shopLabel=[self buttonWithText:head andFrame:CGRectMake(49, 12, 250,5)] ;
shopLabel.tag=12;
//shopLabel.autoresizingMask=UIViewAutoresizingFlexibleRightMargin;
[shopLabel addTarget:self action:#selector(openRestaurantsList) forControlEvents:UIControlEventTouchUpInside];
UIButton *shopLabel1=[self buttonWithText:head1 andFrame:CGRectMake(49, 12, 250,5)] ;
shopLabel1.tag=14;
//shopLabel.autoresizingMask=UIViewAutoresizingFlexibleRightMargin;
[shopLabel1 addTarget:self action:#selector(openRestaurantsList) forControlEvents:UIControlEventTouchUpInside];
cell.detailTextLabel.frame = CGRectMake(49, 30, 150,5);
if(indexPath.row < [newsseperatearray count])
{
UIImage *cellImage = [UIImage imageNamed:#"news.png"];
cell.imageView.image = cellImage;
//NSStringEncoding encoding=NSASCIIStringEncoding;
cell.imageView.frame=CGRectMake(0,0,48,48);
cell.imageView.bounds=CGRectMake(0,0,48,48);
[cell.imageView setClipsToBounds:NO];
NSLog(#"%#",sub);
cell.detailTextLabel.text = sub;
cell.detailTextLabel.backgroundColor = [UIColor clearColor];
}
else
{
UIImage *cellImage = [UIImage imageNamed:#"menu_icon.png"];
cell.imageView.image = cellImage;
//NSStringEncoding encoding=NSASCIIStringEncoding;
cell.imageView.frame=CGRectMake(0,0,48,48);
cell.imageView.bounds=CGRectMake(0,0,48,48);
[cell.imageView setClipsToBounds:NO];
}
[cell addSubview:shopLabel];
[cell addSubview:shopLabel1];
// [cell addSubview:shopLabel2];
}
return cell;
}
`can anybody help me to achieve this?
Make a UITableViewCell subclass, keep that cell style as UITableViewCellStyleSubtitle, and override layoutSubviews in that subclass. You can then change the frame of detailTextLabel (just make sure to call the super implementation of layoutSubviews in your method).

I have seen some posts before, but didn't get the answer yet, thats why i am trying to post again in more effective manner. How can i use check-uncheck functionality in UITableView like below image.
This is table i want when i click on button of any cell, that buttons image will change, not on all cells.
For Check-Uncheck functionality only buttonClicked: method is not enough. You will have also put the condition in cellForRowAtIndexPath: method for which button is selected or which in unselected because cellForRowAtIndexPath: method will call each time when you will scroll your UITableView and cells will be refresh.
And i saw your previous question you're adding two buttons with two action not a good way just change the image of button for check-uncheck.
So here is what i do for this -
#import <UIKit/UIKit.h>
#interface ViewController : UIViewController<UITableViewDelegate, UITableViewDataSource>
{
IBOutlet UITableView *tblView;
NSMutableArray *arrayCheckUnchek; // Will handle which button is selected or which is unselected
NSMutableArray *cellDataArray; // this is your data array
}
#end
Now in ViewController.m class -
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
arrayCheckUnchek = [[NSMutableArray alloc]init];
//Assign your cell data array
cellDataArray = [[NSMutableArray alloc]initWithObjects:#"cell-1",#"cell-2",#"cell-3",#"cell-4",#"cell-5", nil];
// setting all unchecks initially
for(int i=0; i<[cellDataArray count]; i++)
{
[arrayCheckUnchek addObject:#"Uncheck"];
}
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return [cellDataArray count];
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell == nil)
{
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
cell.textLabel.text = [cellDataArray objectAtIndex:indexPath.row];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setFrame:CGRectMake(270.0, 7.0, 30.0, 30.0)];
if([[arrayCheckUnchek objectAtIndex:indexPath.row] isEqualToString:#"Uncheck"])
[button setImage:[UIImage imageNamed:#"uncheck_icon"] forState:UIControlStateNormal];
else
[button setImage:[UIImage imageNamed:#"check_icon"] forState:UIControlStateNormal];
[button addTarget:self action:#selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];
[cell.contentView addSubview:button];
return cell;
}
-(void)buttonClicked:(id)sender
{
//Getting the indexPath of cell of clicked button
CGPoint touchPoint = [sender convertPoint:CGPointZero toView:tblView];
NSIndexPath *indexPath = [tblView indexPathForRowAtPoint:touchPoint];
// No need to use tag sender will keep the reference of clicked button
UIButton *button = (UIButton *)sender;
//Checking the condition button is checked or unchecked.
//accordingly replace the array object and change the button image
if([[arrayCheckUnchek objectAtIndex:indexPath.row] isEqualToString:#"Uncheck"])
{
[button setImage:[UIImage imageNamed:#"check_icon"] forState:UIControlStateNormal];
[arrayCheckUnchek replaceObjectAtIndex:indexPath.row withObject:#"Check"];
}
else
{
[button setImage:[UIImage imageNamed:#"uncheck_icon"] forState:UIControlStateNormal];
[arrayCheckUnchek replaceObjectAtIndex:indexPath.row withObject:#"Uncheck"];
}
}
And finally it will look like -
Tags are useful with customised uitableviewcell designed in IB. If you create cells programmatically, you don't need tags. You use them only to find correct uiview to set properties.
Yes this is simple to set Tags while declaring the classes inside UITableViewCell and identify them using tags. I have posted some sample code for your reference. Am not sure it will solve your problem. You asked how to set tags and identify the classes using tags. So it will give you some basic idea about your question.
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
cell.selectionStyle = UITableViewCellSelectionStyleNone;
label1 = [[UIView alloc] initWithFrame:CGRectMake(2, 20, 15, 15)];
label1.tag = 100;
label1.backgroundColor = [UIColor whiteColor];
label1.layer.cornerRadius = 5;
[cell.contentView addSubview: label1];
label2 = [[UILabel alloc] initWithFrame:CGRectMake(25, 2, 165, 23)];
label2.tag = 101;
label2.font = [UIFont boldSystemFontOfSize:15];
label2.backgroundColor = [UIColor clearColor];
[cell.contentView addSubview: label2];
label3 = [[UILabel alloc] initWithFrame:CGRectMake(190, 2, 90, 23)];
label3.tag = 102;
label3.font = [UIFont systemFontOfSize:14];
label3.textColor = [UIColor colorWithRed:0.14117670588235 green:0.435294117647059 blue:0.847058823529412 alpha:1];
label3.backgroundColor = [UIColor clearColor];
label3.textAlignment = UITextAlignmentRight;
[cell.contentView addSubview: label3];
}
label1 = (UILabel *) [cell.contentView viewWithTag:100];
NSString *string1 = [array1 objectAtIndex:indexPath.row];
label2 = (UILabel *) [cell.contentView viewWithTag:101];
NSString * string2 = [array2 objectAtIndex:indexPath.row];
label3 = (UILabel *) [cell.contentView viewWithTag:102];
NSString * string3 = [array3 objectAtIndex:indexPath.row];
return cell;
}
Please let me know this is useful or not. Otherwise we'll go to some other way.
Happy Coding. Thanks.
i agree with #VakulSaini because u can do this to handle which cell touch or swipe or what ever and this is an ex:
-(void)handleSwipLeft:(UISwipeGestureRecognizer *)gestureRecognizer
{
CGPoint Location = [gestureRecognizer locationInView:self.tableView];
NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:Location];
cell = [tableView cellForRowAtIndexPath:indexPath];
}
Use cellForRowAtIndexPath method of UITableView and in This method Add any component like (UITextField,UILabel ..... etc ) In your UITableViewCell by using [cell.contentView addSubview:YourComponentName]; and give each component to its tag by indexPath.row.
such like ,,,
YourComponentName.tag = indexPath.row;
in my app i have an UITableView with 120 rows and every row has 1 UItextfeilds and 1 Buttons as show in the code bellow :
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier] autorelease];
}
else
{
}
UITextField *NameTextField = [[UITextField alloc] initWithFrame:CGRectMake(0, 10, 230, 28)];
NameTextField.borderStyle = UITextBorderStyleRoundedRect;
NameTextField.delegate = self;
NameTextField.textColor = UIColorFromRGB(0x2A1807);
NameTextField.font = [UIFont fontWithName:#"Helvetica" size:(17.0)];
NameTextField.font = [UIFont boldSystemFontOfSize:20];
NameTextField.tag = [indexPath row ];
NSString *temp = [self.sectionNames objectAtIndex:[indexPath section]];
NameTextField.text = [[self.myDataArray objectForKey:temp] objectAtIndex:[indexPath row]];
[cell.contentView addSubview:NameTextField];
[NameTextField release];
UIButton * aBtn = [UIButton buttonWithType:UIButtonTypeCustom];
UIImage *wijzigImage = [UIImage imageNamed:#"btn_delete.png"];
aBtn.frame = CGRectMake(240, 10, 28, 26);
[aBtn setImage:wijzigImage forState:UIControlStateNormal];
[aBtn addTarget:self action:#selector(deleteCustomCellWithUIButton:) forControlEvents:UIControlEventTouchUpInside];
[cell.contentView addSubview:aBtn];
return cell;
}
i have noticed that the Scrolling is slow and It doesn't go fluently.
any idea ?
Thanks
That's because you create textfields and buttons every time, add it inside if (cell == nil) {...}. The only thing that should be left outside that if is textField text setting.
Btw, your textfield leaks.
I found the solution :
if (cell == nil) {
cell = [[[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier] autorelease];
}
else
{
UITextField *oldTextField = (UITextField *)[cell.contentView viewWithTag:999];
[oldTextField removeFromSuperview];
UIButton *oldBtn = (UIButton *)[cell.contentView viewWithTag:888];
[oldBtn removeFromSuperview];
}
NameTextField.tag = 999;
aBtn.tag = 88;
I am trying to implement UITableview based application. In my tableView their is 10 Section and each section having one row.
I want implement each section have Different type of ContentView(1-8 same ContentView 9th section Different ContentView). I did this code For that.
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 10;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 1;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier1 = #"Cell1";
static NSString *CellIdentifier2 = #"Cell2";
UITextField *textField;
UITextView *textView;
NSUInteger section=[indexPath section];
if(section == 9){
UITableViewCell *cell=[self.tableView cellForRowAtIndexPath:indexPath];
//UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier1];
if(cell==nil){
cell=[[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier1]autorelease];
textView=[[UITextView alloc]initWithFrame:CGRectMake(5, 5, 290, 110)];
[textView setBackgroundColor:[UIColor scrollViewTexturedBackgroundColor
]];
[textView setTag:([indexPath section]+100)];
[cell.contentView addSubview:textView];
}else{
textView=(UITextView*)[cell.contentView viewWithTag:([indexPath section]+100)];
}
return cell;
}else {
UITableViewCell *cell=[self.tableView cellForRowAtIndexPath:indexPath];
// UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier2];
if(cell==nil){
cell=[[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier2]autorelease];
textField=[[UITextField alloc]initWithFrame:CGRectMake(5, 5, 290, 50)];
[textField setBackgroundColor:[UIColor scrollViewTexturedBackgroundColor]];
[textField setTag:([indexPath section]+100)];
[cell.contentView addSubview:textField];
}else{
textField=(UITextField*)[cell.contentView viewWithTag:([indexPath section]+100)];
}
return cell;
}
return nil;
}
My problem are:
1. After type some thing in the UITextField/UITextView i am scrolling in the UITableView. that time all data in the UITableViewCell(UITextField/UITextView) was lose, except last cell data.
2. If i create cell
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
Instead of
UITableViewCell *cell=[self.tableView cellForRowAtIndexPath:indexPath];
Data will repeating . How can i over come this problem?
This line:
UITableViewCell *cell=[self.tableView cellForRowAtIndexPath:indexPath];
Should never appear in your data source cellForRowAtIndexPath method.
Apart from that, your code is OK, except that you are not setting the text field value anywhere. You need a model (such as an array of strings for the 10 textfield values). This model should be updated when the textfields are edited, and in your method above you copy the value back out of the model and into the textfield's text property:
textfield.text = [self.modelArray objectAtIndex:indexPath.section];
The table pools and reuses cells in an unpredictable fashion, so that subview of a cell that just scrolled off the bottom might reappear next at the top, or might be disposed of.
This is why you saw it partially work. The cell's subviews work okay until their cell gets reused or unloaded, then things move to the wrong place or data disappears.
The solution is that your table's datasource needs to hold onto it's own data. This is usually an array representing your model. Your case is a little unusual because you are using the text controls in your table as inputs, rather than display, which is more typical.
I suggest doing it like this:
// in #interface
#property (nonatomic, retain) NSMutableArray *sections;
// in #implementation
#synthesize sections=_sections;
// at some point before the view appears
self.sections = [NSMutableArray array];
for (int i=0; i<10; i++) {
UIControl *textControl;
if (i<9) {
textControl=[[UITextView alloc]initWithFrame:CGRectMake(5, 5, 290, 110)];
} else {
textControl=[[UITextField alloc]initWithFrame:CGRectMake(5, 5, 290, 50)];
}
[textControl setBackgroundColor:[UIColor scrollViewTexturedBackgroundColor]];
[textControl setTag:i+100];
[sections addObject:textControl];
[textControl release];
}
Now your cellForRowAtIndexPath is a little simpler:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier1 = #"Cell1";
static NSString *CellIdentifier2 = #"Cell2";
NSUInteger section=[indexPath section];
if(section == 9) {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier1];
if(cell==nil) {
cell=[[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier1]autorelease];
}
} else {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier2];
if(cell==nil) {
cell = [[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier2]autorelease];
}
}
// who knows what subview this cell has? it might not have one, or it might have the wrong one
// just clean it up to be certain
for (UIView *view in cell.subviews) {
[view removeFromSuperView];
}
// get the textControl we set up for _this_ section/cell
UIControl *textControl = [self.sections objectAtIndex:section];
// now we have a fresh cell and the right textControl. drop it in
[cell addSubview:textControl];
return cell;
}
hey the reason is you are doing this things when cell is nil ? but you are not writing any code when cell is not nil.
look at this example , in this example i am adding image view in tableview cell , hence you can add textviews or any other views like this
UITableViewCell *cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
UIImageView *imgView;
if(cell == nil)
{
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
imgView = [[UIImageView alloc] initWithFrame:CGRectMake(100,0,100,62)];
[imgView setImage:[UIImage imageNamed:#"img.png"]];
imgView.tag = 55;
[cell.contentView addSubview:imgView];
[imgView release];
}
else
{
imgView = (id)[cell.contentView viewWithTag:55];
}
so as showin here imgView = (id)[cell.contentView viewWithTag:55]; you have to give tag to you and write code showing above in else..
Let you try to make the cell labels and textviews by using following code. It works for me.
if (tagvalue ==3) {
static NSString *CellIdentifier = #"Cell3";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle
reuseIdentifier:CellIdentifier] autorelease];
}
lbl7 = [[UILabel alloc] init];
[lbl7 setFont:[UIFont boldSystemFontOfSize:20]];
[cell.contentView addSubview:lbl7];
lbl7.backgroundColor = [UIColor clearColor];
lbl7.frame = CGRectMake(120, 5, 0, 40);
lbl7.tag = 70;
[lbl7 release];
lbl8 = [[UILabel alloc] init];
[lbl8 setFont:[UIFont boldSystemFontOfSize:18]];
[cell.contentView addSubview:lbl8];
lbl8.backgroundColor = [UIColor clearColor];
lbl8.textColor = [UIColor grayColor];
lbl8.frame = CGRectMake(120, 50, 0, 40);
lbl8.tag = 80;
[lbl8 release];
lbl7 = (UILabel*)[cell.contentView viewWithTag:70];
lbl8 = (UILabel*)[cell.contentView viewWithTag:80];
lbl7.text = [[rowsarray objectAtIndex:row]objectForKey:#"name"];
lbl8.text = [[rowsarray objectAtIndex:row]objectForKey:#"flavour"];
[lbl7 sizeToFit];
[lbl8 sizeToFit];
return cell;
}
if (tagvalue ==4) {
static NSString *CellIdentifier = #"Cell4";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
}
lbl9 = [[UILabel alloc] init];
[lbl9 setFont:[UIFont boldSystemFontOfSize:20]];
[cell.contentView addSubview:lbl9];
lbl9.backgroundColor = [UIColor clearColor];
lbl9.frame = CGRectMake(120, 5, 0, 40);
lbl9.tag = 90;
[lbl9 release];
lbl10 = [[UILabel alloc] init];
[lbl10 setFont:[UIFont boldSystemFontOfSize:18]];
[cell.contentView addSubview:lbl10];
lbl10.backgroundColor = [UIColor clearColor];
lbl10.textColor = [UIColor grayColor];
lbl10.frame = CGRectMake(120, 50, 0, 40);
lbl10.tag = 100;
[lbl10 release];
lbl9 = (UILabel*)[cell.contentView viewWithTag:90];
lbl10 = (UILabel*)[cell.contentView viewWithTag:100];
lbl9.text = [[rowsarray objectAtIndex:row]objectForKey:#"name"];
lbl10.text = [[rowsarray objectAtIndex:row]objectForKey:#"flavour"];
[lbl9 sizeToFit];
[lbl10 sizeToFit];
return cell;
}
I had same issue. Its not the problem with table class. The issue is at the place where you are calling this tableviewcontroller. First make the object of this call in .h and then allocate in .m, thats it..
When I was declaring in viewdidload like tbl *t = [self.storyboard...];, I was also facing the same problem. But when I put tbl *t; in .h problem solved.
Is it possible to check uitableviewcell accessoryview contains image or not?
For example
if([self.tableView cellForRowAtIndexPath:indexPath].accessoryView == [UIImage imageNamed:#"selected.png"] )
Some this like that or with different method.
Thank you
By default accessoryView will be null.
You can check for -
if (self.tableView.accessoryView) {
// An image is present
}
For my app I have created a custom cell and then added the imageView at the contentView
But for your requirement you can do something like this
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 20, 20)];
cell.accessoryView = imageView];
imageView.tag = 3;
[imageView release];
}
NSArray *subviews = [[NSArray alloc] initWithArray:cell.contentView.subviews];
UIImageView *imageView;
for (UIView *subview in subviews)
{
if([subview isKindOfClass:[UIImageView class]] && subview.tag == 3);
imageView = [subview copy];
}
[subviews release];
if([selectedArray containsObject:indexPath])
imageView.image = [UIImage imageNamed:#"Selected.png"];
else
imageView.image = [UIImage imageNamed:#"Unselected.png"];
}
And in this method do the same thing to get the imageView object
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
First:
if([self.tableView cellForRowAtIndexPath:indexPath].accessoryView == [UIImage imageNamed:#"selected.png"] )
this is wrong... acessaryview is not an image, it's UIView.
Check for:
if(nil != [self.tableView cellForRowAtIndexPath:indexPath].accessoryView)
{
// It has got something in it...
}
else
{
//create an accessary view....
}
This is how I implement multiselect tableview with checkboxes in each cell
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *MyIdentifier = #"MyIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
UIButton *disclosureButton = [UIButton buttonWithType:UIButtonTypeCustom];
[disclosureButton setFont:[UIFont fontWithName:#"Arial-BoldMT" size:12.0]];
[disclosureButton setBackgroundImage:[UIImage imageNamed:#"checkboxoff.png"] forState:UIControlStateNormal];
disclosureButton.tag = 0;
[disclosureButton setFrame:CGRectMake(0,0, 30,30)];
[disclosureButton addTarget:self action:#selector(select:event:) forControlEvents:UIControlEventTouchUpInside];
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:MyIdentifier] autorelease];
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
[cell.textLabel setUserInteractionEnabled:YES];
[cell setImage:[UIImage imageNamed:#"bluemappointer.png"]];
[cell setAccessoryView:disclosureButton];
}
else{
int n = indexPath.row;
if([selectedPlaces objectForKey:indexPath] != nil){
disclosureButton.tag = 1;
[disclosureButton setBackgroundImage:[UIImage imageNamed:#"checkboxon.png"] forState:UIControlStateNormal];
[cell setAccessoryView:disclosureButton];
}
else{
[disclosureButton setBackgroundImage:[UIImage imageNamed:#"checkboxoff.png"] forState:UIControlStateNormal];
disclosureButton.tag = 0;
[cell setAccessoryView:disclosureButton];
}
}
NSString *name = [tableData objectAtIndex:indexPath.row];
[cell.textLabel setText:name];
return cell;
}
iam building an application in which iam showing the 5 small images in a single row of the UITable view cell. i want to make selection of row on each image clicked not on the selection of row .
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 160;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"simpsons"] autorelease];
}
//cell.textLabel.text = [theSimpsons objectAtIndex:indexPath.row];
//NSString *imageName = [NSString stringWithFormat:#"%d.png", indexPath.row];
//cell.imageView.image = [UIImage imageNamed:imageName];
image1= [[UIImageView alloc] initWithFrame:CGRectMake(5.0,10.0,78, 74)];
[cell.contentView addSubview:image1];
image1.image = [UIImage imageNamed:#"0.png"];
image2= [[UIImageView alloc] initWithFrame:CGRectMake(80.0,10.0,78, 74)];
[cell.contentView addSubview:image2];
image2.image = [UIImage imageNamed:#"1.png"];
image3= [[UIImageView alloc] initWithFrame:CGRectMake(170.0,10.0,78, 74)];
[cell.contentView addSubview:image3];
image3.image = [UIImage imageNamed:#"2.png"];
image4= [[UIImageView alloc] initWithFrame:CGRectMake(240.0,10.0,78, 74)];
[cell.contentView addSubview:image4];
image4.image = [UIImage imageNamed:#"3.png"];
return cell;
}
i want on each image selection only a new row will we opened not on row click ?????
Sure.
1: you can custom a cell with a Button(show your image and clickable) and other controls.
Then set the tag of each button in a cell.
2: In the IBAction event of each button, record the tag and use delegate to select relevant row.
Instad of using UIImageView.Use UIButton.In Custom Style..And Place Image In UIButton Background,So Finally Your Image Will Appear And When You Click On Button You TableRow Is Not Selected.
