Im kind of new to this and would really like to implement this in my project, but Im missing something. If I have in the CustomCell class two buttons how does the action gets connected to the TableViewController? and how would I know which of both buttons was pressed?

I am new to iphone and I am trying to add the button in uitable with the following code but when I press the button I get GDB:Program received signal:”SIGBART”

***************************************
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
//more stuf here
UIButton *myButton = [UIButton buttonWithType:UIButtonTypeContactAdd];
[myButton setBackgroundColor:[UIColor greenColor]];
myButton.titleLabel.text = @”Add”;
[myButton addTarget:self action:@selector(butonMethod:)
forControlEvents:UIControlEventTouchUpInside];
[cell.contentView addSubview:myButton];
}
*****************************************
this is the method
- (void)buttonMethod:(UIButton *)sender {

// method for finding what button was pressed

NSIndexPath *indexPath = [theTableView indexPathForCell:(UITableViewCell *)[[sender superview] superview]];

NSInteger section = indexPath.section;
NSInteger row = indexPath.row;

NSLog(@”Button is in section %d and row %d”, section, row);

}
in my .h files

UIButton *buttonMethod;
- (void)buttonMethod:(UIButton *)sender;

please could some one tell me what is wrong thanks in advance

Hi,

I’ve adjusted the code to work out the UITableView as well, useful for multiple table views.

UITableViewCell *currentCell = (UITableViewCell *)[[sender superview] superview];
UITableView *currentTable = (UITableView *)[currentCell superview];
NSIndexPath *indexPath = [currentTable indexPathForCell:currentCell];

Exactly what I needed. Thanks!!

You rock man… super simple and easy to implement!

@Rob above, make sure it is within a uitableviewcontroller and you have setup the dataSource and delegate. The code should be something like this within the parent view controller for that table:

- (void)buttonMethod:(UIButton *)sender {

// method for finding what button was pressed

NSIndexPath *indexPath = [self.tableView indexPathForCell:(UITableViewCell *)[[sender superview] superview]];

NSInteger section = indexPath.section;
NSInteger row = indexPath.row;

NSLog(@”Button is in section %d and row %d”, section, row);

}

and then put this in the .h file

UIButton *buttonMethod;

and

- (void)buttonMethod:(UIButton *)sender;

Hi Mike,
Thanks for the awesome tip!
I’m trying to do the same thing, but I’m getting an error in my TableViewCell subclass for the “NSIndexPath *indexPath = [self.tableView indexPathForCell:(UITableViewCell *)[[sender superview] superview]];” saying that the “Request for member ‘tableView’ in something that is not a structure or union”.
Do I need to pass that down somehow?
Thanks again for getting me one step closer!!
