Created a UITableView programmatically, data in my tableview in iPad Master View Controller is loaded dynamically, i am putting a button in the last cell, but the button is showing up again in the tableview underneath the cell... First time when the code is executed, the button appears only once, but next time it shows up twice... Here is the code...
- (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];
}
if([_objects count] > 1)
{
if(indexPath.row == [_objects count])
{
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
//set the position of the button
button.frame = CGRectMake(cell.frame.origin.x + 50, cell.frame.origin.y + 15, 225, 30);
[button setTitle:#"Hide me" forState:UIControlStateNormal];
[button addTarget:self action:#selector(customActionPressed) forControlEvents:UIControlEventTouchUpInside];
button.backgroundColor= [UIColor clearColor];
[cell.contentView addSubview:button];
}
else
{
cell.textLabel.textAlignment = NSTextAlignmentCenter;
cell.selectionStyle = UITableViewCellSelectionStyleBlue;
cell.textLabel.textColor = [UIColor colorWithRed:0/255.0 green:100.0/255.0 blue:220.0/255.0 alpha:1.0];
cell.textLabel.font = [UIFont fontWithName:#"Helvetica-Bold" size:13];
cell.textLabel.text = [_objects objectAtIndex:indexPath.row];
NSLog(#"%#", [_objects objectAtIndex:indexPath.row]);
}
}
return cell;
}
for ex:: here is a snapshot of the tableview (how can i put the image here???)

UIButton is appearing again here in the tableview
Here is the image link http://s10.postimg.org/fwarb2661/i_OS_Simulator_Screen_shot_28_Dec_2013_10_57_32_A.png
any help is appreciated, thanks in advance..
Please write bellow code :
if (cell)
{
cell =nil;
}
before creating your tableview cell
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
//write here
if (cell)
{
cell =nil;
}
//*
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
For set background image in cell plese use bellow code :-
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(X, Y, 277, 58)];
imageView.backgroundColor = [UIColor clearColor];
imageView.opaque = NO;
imageView.image = [UIImage imageNamed:#"yourImage.png"];
cell.backgroundView = imageView;
Probably because your table view is using the same cell again.
Make sure you delete the button from the cell every time.
Would help to see your code so I can point to you exact location...
Try this:
(void)prepareForReuse {
[super prepareForReuse];
}
In the method set the button to nil or any other elements showing twice. The cell is being reused and you need to run prepareForReuse to empty the old cells.

I have an application in which i am loading two types cells in a table view from two different custom classes.I have 5 sections in my table view each having single rows.I am added one button to my cell and when clicking on it it will change the image of the button .as button.selected=YES;ike that.But my problem is when i am scrolling the cells r repeating,ie if i selected a button in a row then the background image of that row only need to change.But in my case some cell buttons are also changing.Here is how i am adding the things.`
- (UITableVieCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

i have 10 sections each returning 1 row.My problem is i need to change the image of the button when clicked.I was adding that button in the customcellwith image class as
[lbutton1 setImage:[UIImage imageNamed:#"sdsd.png"] forState:UIControlStateNormal];
[lbutton1 setImage:[UIImage imageNamed:#"sdsdsd.png"] forState:UIControlStateSelected];
lbutton1.selected=NO;`
and in my code i have added `
UIButton *button = (UIButton *)sender;
button.selected=YES;
` But the problem here is it also changing the button in another section also.Can anybody help me?
Maybe there is some problem with your check condition for if (indexPath.section == 0 && indexPath.row==0). This check will always NO when it's not the first section. So your cell will not be reused for your class CustomCell except for your first section's first row.
I am not sure if I fully understand the problem, but I think you want to move background creation also behind the if. Once it will be changed you should reset it and they way it is now it won't be reseted (just like you reset selection style you should reset background)
if (cell == nil)
{
cell = [[[CustomCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier1] autorelease];
}
cell.backgroundView = [ [[UIImageView alloc] initWithImage:[ [UIImage imageNamed:#"dhjkhs.png"] stretchableImageWithLeftCapWidth:0.0 topCapHeight:5.0] ]autorelease];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
cell.datelabel.text=#"skhfkhdf";
cell.nameLabel.text=#"dsdbjsbjf";
cell.msg.text=#"dshjshhshd";
[cell.lbutton addTarget:self action:#selector(callAction:) forControlEvents:UIControlEventTouchUpInside];
cell.myImageView.image=[UIImage imageNamed:#"sdsd.png"];
cell.llabel.text=#"sdjkjskljdls";
cell.llabel.tag=indexPath.section+1;
return cell;
In my app i am customised the UITableView Cell with four UITextViews. Whenever i added data to the tableview and reload it. The text in the UITableViewCell get override with the previous texts.
I tried different approaches but couldn't figure out what was the problem.
I am using TableView in View Controller.
Here is the Code i used in my table View cell?
if ( [tableView isEqual:self.tableActions])
{
//Setting the text empty
static NSString *CellIdentifier = #"ActionsIdentifier";
cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell == nil)
{
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
}
NSLog(#"Index Path %i",[indexPath row]);
ActionDetails *actiondetails = [actionArray objectAtIndex:[indexPath row]];
NSLog(#"Action Text %#",actiondetails.actions);
//Actions
actionText=[[UITextView alloc] initWithFrame:CGRectMake(10, 5, 230,30)];
actionText.font = [UIFont systemFontOfSize:17.0];
actionText.editable = NO;
actionText.textColor=[UIColor blackColor];
actionText.text = actiondetails.actions ;
actionText.userInteractionEnabled = NO;
actionText.backgroundColor = [UIColor clearColor];
[cell.contentView addSubview:actionText];
//Owner
ownerBy=[[UITextView alloc] initWithFrame:CGRectMake(230, 5, 230,30)];
ownerBy.font = [UIFont systemFontOfSize:17.0];
ownerBy.textColor=[UIColor blackColor];
ownerBy.textAlignment = UITextAlignmentCenter;
ownerBy.text = actiondetails.owner;
ownerBy.editable = NO;
ownerBy.userInteractionEnabled = NO;
ownerBy.backgroundColor = [UIColor clearColor];
[cell.contentView addSubview:ownerBy];
}
ScreenShot
Thanks for your help guys.
Much Appreciated.
This happened to me a other day, the solution that I came up with was removing all subview from the cell after creating the cell in the if statement.
if(cell == nil)
{
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
}
if ([cell.contentView subviews]){
for (UIView *subview in [cell.contentView subviews]) {
[subview removeFromSuperview];
}
}
Remove cell identifier of Tableview otherwise take Customcell for the Tableview..
Just simple try this way :
{
//Setting the text empty
static NSString *CellIdentifier = #"ActionsIdentifier";
cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
**// if(cell == nil) // comment this line in your code ,its work
// {**
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
**// }**
NSLog(#"Index Path %i",[indexPath row]);
ActionDetails *actiondetails = [actionArray objectAtIndex:[indexPath row]];
NSLog(#"Action Text %#",actiondetails.actions);
//Actions
actionText=[[UITextView alloc] initWithFrame:CGRectMake(10, 5, 230,30)];
actionText.font = [UIFont systemFontOfSize:17.0];
actionText.editable = NO;
actionText.textColor=[UIColor blackColor];
actionText.text = actiondetails.actions ;
actionText.userInteractionEnabled = NO;
actionText.backgroundColor = [UIColor clearColor];
[cell.contentView addSubview:actionText];
//Owner
ownerBy=[[UITextView alloc] initWithFrame:CGRectMake(230, 5, 230,30)];
ownerBy.font = [UIFont systemFontOfSize:17.0];
ownerBy.textColor=[UIColor blackColor];
ownerBy.textAlignment = UITextAlignmentCenter;
ownerBy.text = actiondetails.owner;
ownerBy.editable = NO;
ownerBy.userInteractionEnabled = NO;
ownerBy.backgroundColor = [UIColor clearColor];
[cell.contentView addSubview:ownerBy];
}
You are reusing the cell. Reused cell already has UITextview added to it.So you are overriding on it.
You must shift all your code of creating and adding UITextView to.
If(cell==nil)
{
}
After which you only need to set the Text to UITextview.
when your view did appear write reload your table view.
-(void)viewDidAppear:(BOOL)animated {
[tableView reloadData];
}
change your cellForRowAtIndexPath method
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *CellIdentifier = [NSString stringWithFormat:#"S%1dR%1d",indexPath.section,indexPath.row];
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
// your code
}
// your code
return cell;
}
for (id vw in [[cell contentView] subviews]) {
if ([vw isKindOfClass:[UILabel class]])
{
UILabel *label = (UILabel *)vw;
[label removeFromSuperview];
}
}
for (id vw in [cell subviews]) {
if ([vw isKindOfClass:[UILabel class]])
{
UILabel *label = (UILabel *)vw;
[label removeFromSuperview];
}
}
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;
First question on this site, although I have been around for a while behind the scenes. I have a problem that I have been racking my head on for the last two days and I hope someone can shed some light on it for me.
I have a UITableView, which is loaded from a SQL database. It has 15 entries in it. I have inserted an extra cell at the beginning of the UITableView. This extra cell is for a UITextField and UIButton which adds an item into the database.
When the view is loaded, the first cell with the custom objects shows fine, and the rest of the table is filled with items from the database and looks just how it should. However, when the UITableView is scrolled down so the first cell is out of view, then back up, it takes the value of the 11th row item and shows it over top the first cell.
Here is my code:
- (UITableViewCell *)tableView:(UITableView *)popTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
static NSInteger NameTag = 1;
UITableViewCell *cell = [popTableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
CGRect frame;
frame.origin.x =50;
frame.origin.y =10;
frame.size.height =22;
frame.size.width =275;
UILabel *nameLabel = [[UILabel alloc] initWithFrame:frame];
nameLabel.tag = NameTag;
nameLabel.opaque = YES;
nameLabel.textColor = [UIColor grayColor];
nameLabel.backgroundColor = [UIColor clearColor];
[cell.contentView addSubview:nameLabel];
[nameLabel release];
}
int row = [indexPath row];
if (row == 0) {
UIButton *buttonLeft = [UIButton buttonWithType:UIButtonTypeCustom];
[buttonLeft setFrame: CGRectMake( 205, 6, 40, 33)];
[buttonLeft addTarget:self action:#selector(addToList:) forControlEvents:UIControlEventTouchUpInside];
[cell addSubview:buttonLeft];
//No Alloc for txtField, it is built in IB
[txtField setBorderStyle:UITextBorderStyleNone];
[txtField setFrame: CGRectMake( 17, 12, 180, 23)];
txtField.backgroundColor = [UIColor clearColor];
[txtField addTarget:self action:#selector(textFieldDidChange:) forControlEvents:UIControlEventEditingChanged];
txtField.clearButtonMode = UITextFieldViewModeAlways;
}else{
UILabel * nameLabel = (UILabel *) [cell.contentView viewWithTag:NameTag];
Add *theObj = [self.theArray objectAtIndex:indexPath.row - 1];
[nameLabel setText:theObj.itemName];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
UIImageView *imageView = [cell viewWithTag:kTagCellImageView];
if (imageView == nil) {
imageView = [[UIImageView alloc]initWithFrame:CGRectMake(10.0, 10.0, 13.0, 25.0)];
imageView.backgroundColor = [UIColor clearColor];
imageView.tag = kTagCellImageView;
[cell.contentView addSubview:imageView];
}
if([theObj.itemName isEqualToString:#"First Street"]){
imageView.frame = CGRectMake(14,10,13,25);
[imageView setImage:[UIImage imageNamed:#"firststreet"]];
}
else if([theObj.itemName isEqualToString:#"Second Street"]){
imageView.frame = CGRectMake(8,12,29,20);
[imageView setImage:[UIImage imageNamed:#"second"]];
}
else if([theObj.itemName isEqualToString:#"Main Street"]){
imageView.frame = CGRectMake(15,10,13,25);
[imageView setImage:[UIImage imageNamed:#"mainstreet"]];
}
else{
imageView.frame = CGRectMake(8,8,25,25);
[imageView setImage:[UIImage imageNamed:#"iconcustom"]];
}
NSLog(#"%#",itemName);
NSLog(#"%#",itemCategory);
}
return cell;
}
Also here is my cellForRow:
- (NSInteger)tableView:(UITableView *)popTableView numberOfRowsInSection:(NSInteger)section {
return [self.theArray count] + 1; //Add Extra cell to beginning
}
Any ideas would be greatly appreciated.
You need to use a different reuseIdentifier for your first cell. Try this:
NSString *cellIdentifier;
if (indexPath.row == 0) {
cellIdentifier = #"first";
} else {
cellIdentifier = #"not first";
}
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier] autorelease];
// .. cell initialization
}
Obligatory tangential answer - have you thought about setting the tableHeaderView on the UITableView instead? I think that'd accomplish what you're trying to do in a cleaner way (in that it adds an arbitrary view to the top of the table).
Just create a UIView with your "add a new item" controls in it and then set it as the header view when first creating the table.
The issue is here
static NSString *CellIdentifier = #"Cell";
static NSInteger NameTag = 1;
UITableViewCell *cell = [popTableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
you are dequeueing all of the cells with the same identifier. Row 1 (index 0) needs to have its own CellIdentifier. Also it looks like you keep adding subviews to the same cells that you dequeue. On your if(cell == nil) check you may want to decide if you want to remove all of the cells contentView subviews or reuse them.
Please look at my following code snippet. I place check box in to my cell , i can able to check or uncheck the checkbox. but when i scroll the table view the checkbox's check mark is getting hidden.
i mean i set the check mark by setting the image.
Please anybody help me to solve this problem.
Thanks for your time.

Taken from here
If I understand the TableView concept correctly, you need to save the checkmark setting somewhere else. If your cell gets scrolled out of view the TableViewController might release the cell. Then, when you're asked to re-create the cell in your delegate, you have to restore it in the same state as before.
In DidSelectRowAtindexPath:
if ([set containsObject:indexPath])
{
[set removeObject:indexPath];
}
else
{
[set addObject:indexPath];
}
and in CellForRpwAtIndexPath:
if ([set containsObject:indexPath])
{
cell.imgView.image=[UIImage imageNamed:#"chealBox1.png"];
}
else
{
cell.imgView.image=[UIImage imageNamed:#"chealBox2.png"];
}
here set is NSMutableSet and you have to make property and synthesize and alloc as well in viewDidLoad...will work definitely...
