UITableView indexPath.row issue - ios

Question

I am using a tableView which loads a custom UITableViewCell with a "Tap" button inside it. A method is called when user clicks the button.
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{...
[btnRowTap addTarget:self action:#selector(didButtonTouchUpInside:) forControlEvents:UIControlEventTouchDown];
...
return cell;
}
In the didButtonTouchUpInside method, Im trying to retrieve the value of row selected in the following way:
-(IBAction)didButtonTouchUpInside:(id)sender{
UIButton *btn = (UIButton *) sender;
UITableViewCell *cell = (UITableViewCell *)btn.superview;
NSIndexPath *indexPath = [matchingCustTable indexPathForCell:cell];
NSLog(#"%d",indexPath.row);
}
The problem is that on clicking button at any row, I am getting the same value of 0 every time.
Where am I going wrong?

Answer 1

You must NOT rely on the view hierarchy of a UITableViewCell. This approach will fail in iOS7, because iOS7 changes the view hierarchy of the cell. There will be an additional view between your button and the UITableViewCell.
There are better ways to handle this.
Convert the button frame so it is relative to the tableview
ask the tableView for the indexPath at the origin of the new frame
.
-(IBAction)didButtonTouchUpInside:(id)sender{
UIButton *btn = (UIButton *) sender;
CGRect buttonFrameInTableView = [btn convertRect:btn.bounds toView:matchingCustTable];
NSIndexPath *indexPath = [matchingCustTable indexPathForRowAtPoint:buttonFrameInTableView.origin];
NSLog(#"%d",indexPath.row);
}

Answer 2

set Button tag in to cellForRowAtIndexPath method Befor setting Method like
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{...
btnRowTap.tag=indexPath.row
[btnRowTap addTarget:self action:#selector(didButtonTouchUpInside:) forControlEvents:UIControlEventTouchDown];
...
return cell;
}
and your tapped cell getting like this:-
-(IBAction)didButtonTouchUpInside:(id)sender{
{
UIButton *button = (UIButton*)sender;
NSIndexPath *indPath = [NSIndexPath indexPathForRow:button.tag inSection:0];
//Type cast it to CustomCell
UITableViewCell *cell = (UITableViewCell*)[tblView1 cellForRowAtIndexPath:indPath];
NSLog(#"%d",indPath.row);
}

Answer 3

try like this,if you are adding button to cell content view then use below code.
UITableViewCell *buttonCell = (UITableViewCell *)sender.superview.superview;
UITableView* table1 = (UITableView *)[buttonCell superview];
NSIndexPath* pathOfTheCell = [table1 indexPathForCell:buttonCell];
int rowOfTheCell = [pathOfTheCell row];
int sectionOfTheCell = [pathOfTheCell section];

Answer 4

btn.superview is contentView of UITableviewCell. Use btn.superview.superview instead.

Answer 5

if you already knew the value inside the cell, then
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewCell *currentCell = [self tableView:tableView cellForRowAtIndexPath:indexPath];
if ([currentCell.textLabel.text isEqualToString:#"Your Cell Text value" ]){
//Do theStuff here
}
}

Answer 6

here is the code for your ibAction.you dont need to set any tag or anything else
-(IBAction)didButtonTouchUpInside:(id)sender{
NSIndexPath *indexPath =
[tbl
indexPathForCell:(UITableViewCell *)[[sender superview] superview]];
}
