I have a Uibutton in one class and Uitable in different Class...
Now i want to compare IndexPAth(Particular cell Position) with Uibutton Of Different class...
Actually i want to print Different different value on particular cell Which I am Fetching from Different Different Uibutton`s Methods from another class....
Here is My code....
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
//- (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];
}
if(indexPath == btn1){ // This is the Line What i want , i am trying this but dont go inside the condition..
UILabel *lbl = [[UILabel alloc] initWithFrame:CGRectMake(200, 5, 290, 60)];
lbl.backgroundColor = [UIColor clearColor];
//lbl.editable = NO;
lbl.font = [UIFont fontWithName:#"Helvetica-Bold" size:25];
// txtView1.text= textviewstring;
// txtView1.text = #"Personal";
if([fetchFormArray222 count]<1){
lbl.text=#"";
}
else{
lbl.text = [fetchFormArray222 objectAtIndex:0];
}
// [txtView1 setDelegate:self];
lbl.textColor = [UIColor blackColor];
lbl.textAlignment = UITextAlignmentLeft;
[[cell contentView] addSubview:lbl];
}
else {
}
Check the apple documentation of UITableView.
Have you tried to use the button in the other class to perform a new fetch in the class you're focusing on that loads fetctFormArray222 and then reload the UITableView?

For those that are familiar with FPPopOver: https://github.com/50pixels/FPPopover
Can the cells display subtitle? I had to attach my UITableViewController to a nib.
In the Storyboard I have the cell set up to show subtitle, however, when the popOver appears on the iPhone, only cell.textLabel.text is visible - cell.detailTextLabel.text is not appearing.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
if (cell==nil)

cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
NSString *entityName= [[managedObject entity]name];
cell.textLabel.text = [NSString stringWithFormat:#"%# %i", entityName, [indexPath row]];
cell.detailTextLabel.text = #"Subtitle";
}
Here is the image:
Update
After using Labels to display the subtitle, after scrolling the cell back into the view, the following happens:
if it's not working at all then alternative of that is you can use lable and set frame of lable as detail text has and add that lable as cell.contentview addsubview so this way you'll get your detail text on your tableview cell.

I have a UItableView where every UITableViewCell is containing a UISwitch .Now my question is when i will click in one switch then how can i OFF other switches of the UITableViewCell
In my code i have already made the view and i can ON/OFF the switches.But i want to OFF all other switches except my selected switch.
Please some help me by giving an example or source code example.
With Best Regards
Edit
My 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] autorelease];
switchview = [[UISwitch alloc] initWithFrame:CGRectZero];
cell.accessoryView = switchview;
switchCondition = NO;
[switchview setOn:NO animated:YES];
[switchview addTarget:self action:#selector(updateSwitchAtIndexPath:) forControlEvents:UIControlEventValueChanged];
[switchview release];
}
if(switchCondition == YES){
[switchview setOn:YES animated:YES];
}
cell.selectionStyle = UITableViewCellSelectionStyleNone;
cell.contentView.backgroundColor = [UIColor clearColor];
cell.textLabel.text = [NSString stringWithFormat:#"%#",[cellValueArray objectAtIndex:indexPath.row]];
return cell;
}
- (void)updateSwitchAtIndexPath:(UISwitch*)sender {
if(sender.on){
switchCondition = YES;
[table reloadData];
}
}
Update your data model used by the table's data source, then reload the table (or at least the visible rows). This will cause each row to reload and each switch will get updated with the latest data.
Edit: Here's an updated version of your code:
You need an instance variable to track the state of each switch. Create an array to hold the YES and NO values. In the code below I will assume there is an instance variable named switchConditions of type NSMutableArray that has been setup with NSNumber objects representing the YES and NO values for each row. This is similar to your cellValueArray. You should also get rid of your switchView and switchCondition instance variables.
- (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.selectionStyle = UITableViewCellSelectionStyleNone;
UISwitchView *switch = [[UISwitch alloc] initWithFrame:CGRectZero];
cell.accessoryView = switch;
[switchview addTarget:self action:#selector(updateSwitchAtIndexPath:) forControlEvents:UIControlEventValueChanged];
[switch release];
}
UISwitchView *switch = (UISwitchView *)cell.accessoryView;
switch.tag = indexPath.row; // This only works if you can't insert or delete rows without a call to reloadData
BOOL switchState = [switchConditions[indexPath.row] boolValue];
switch.on = switchState; // this shouldn't be animated
cell.contentView.backgroundColor = [UIColor clearColor];
cell.textLabel.text = cellValueArray[indexPath.row];
return cell;
}
- (void)updateSwitchAtIndexPath:(UISwitch*)switch {
NSInteger row = switch.tag;
if (switch.on){
// This switch is on, turn all of the rest off
for (NSUInteger i = 0; i < switchConditions.count; i++) {
switchConditions[i] = #NO;
}
switchConditions[row] = #YES;
[self.tableView reloadData];
} else {
switchConditions[row] = #YES;
}

I have uitableview created with IB. And I designed my own uitableviewcell (it is subclass of uiatbleviewcell and has its own xib file). How to add it to my uitableview??
I tried
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath
*)indexPath {
static NSString *CellIdentifier = #"myCell";
myCell *cell = (myCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
NSArray *xib = [[NSBundle mainBundle] loadNibNamed:#"myCell" owner:self options:nil];
cell = [xib objectAtIndex:0];
}
// Configure the cell...
cell.title.text = #"tableCell";
cell.preview.text = #"preview";
cell.postedTime.text = #"right now";
return cell;
}
It works incorrect. I can't include images here, because my rep is 10 (need min. 11 to upload images). So here's link to show my bad results. This is what i want: http://img708.imageshack.us/img708/5082/20120903153930.png

u need to change the default height of each cell using method
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 62.0f; // enter value if u know or test
}
hope it helps. happy coding :)
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if(btnTag == 1)
return [array1 count];
if(btnTag == 2)
return [array2 count];
return YES;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 62;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
CustomCell *cell = [[CustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
if(btnTag == 1)
{
cell.teamLabel.text = #"i am 'A'cell";
}
if(btnTag == 2)
{
cell.teamLabel.text = #"i am 'B'cell";
}
return cell;
}
You dont have to add it like this on your xib file. Acc to what you have done you have added a UITableViewCell on another UITableView. Do you really want to create a custom cell ?? You can simply add any data into the UITableView in the
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
Then add the cell's accordingly like UILabels , UIImageViews etc .
cell = [tableView dequeueReusableCellWithIdentifier:nil];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:nil ];
}
UIButton *Imagebutton = [[UIButton alloc]initWithFrame:CGRectMake(10, 5, 30, 30)];
UIImage *img = [UIImage imageNamed:#"Lock Unlock.png"];
[Imagebutton setImage:img forState:UIControlStateNormal];
[Imagebutton addTarget:self action:#selector(aMethod1:) forControlEvents:UIControlEventTouchDown];
[cell.contentView addSubview:Imagebutton];
UILabel *MealsforLabel = [[UILabel alloc]initWithFrame:CGRectMake(50, 10, 140, 30)];
MealsforLabel.backgroundColor = [UIColor clearColor];
[cell.contentView addSubview:MealsforLabel];
cell.textLabel.textColor = [UIColor blackColor];
cell.textLabel.textColor=[UIColor whiteColor];
cell.selectionStyle = UITableViewCellSelectionStyleGray;
return cell;
Something like the above.
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.
i am displaying array of data in a table view.
my code for that is like this.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
}
// Set up the cell
CGRect labelFrame = CGRectMake(0,0 , 100, 25);
itemNameLabel = [[[UILabel alloc] initWithFrame:labelFrame] autorelease];
itemNameLabel.textAlignment = UITextAlignmentLeft;
itemNameLabel.backgroundColor = [UIColor clearColor];
itemNameLabel.text = [tableData objectAtIndex:indexPath.row];
CGRect anotherLabelFrame = CGRectMake(120, 0, 100, 25);
quantityLabel = [[[UILabel alloc] initWithFrame:anotherLabelFrame] autorelease];
quantityLabel.textAlignment = UITextAlignmentLeft;
quantityLabel.backgroundColor = [UIColor clearColor];
MyGroceryListAppDelegate *appDelegate = (MyGroceryListAppDelegate *)[[UIApplication sharedApplication] delegate];
Category *obj = (Category *)[appDelegate.itemsList objectAtIndex:indexPath.row];
quantityLabel.text = [NSString stringWithFormat:#"%d",obj.quantity];
[cell.contentView addSubview:itemNameLabel];
[cell.contentView addSubview:quantityLabel];
return cell;
}
how can i resolve this.
can any one please help me.
Thank u in advance.
i am giving text for itemNameLabel is using array and for quantityLabel using class object.
so,when i scrolling table view the array names are override on other label,but quantity label is not overriding because it is from class.
i need to display itemNameLabel from array since it changes it value.
when i scroll table view my tableview is looking like this.
Ideally you should alloc all lable in this section
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
}
and in the else part you should just Tag those labels and reuse after it but there is another short and sweet way
if Application is not much resource consuming
change
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
to
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:nil];
Try setting Height for each row using the function
- (CGFloat)tableView:(UITableView *)tv heightForRowAtIndexPath:(NSIndexPath *)indexPath {
return 100.0f;
}
