Question

When I select buttons within these UITableViewCells, the button sometimes passes data from the wrong row. In this table view, there are 10 sections, each with a section header and with only 1 row. The row height takes up most of the screen, as there are 6 buttons within it. Each UIButton, when selected, opens a new viewcontroller with an enlarged view of the button’s image (removed this code to make it more readable here).

Here is the problem: each button successfully pushes a modal viewcontroller; however, as I scroll down, sometimes the buttons pass the data from the same button from the section below it (e.g. button1 in section 4 when clicked may pass the data for button1 in section 5). Similarly, as I scroll back up, sometimes the buttons pass the data from the same button from the section above it (e.g. button5 in section 7 when clicked may pass the data for button5 in section 6).

I think this problem occurs because the iPhone is pulling the most recently loaded cell (when cellForRowAtIndexPath is called), but I would like it to pass the data for the row in which the button is located.

Thoughts? Thanks in advance for any help you can provide.

Edit: Added data code as requested

- (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];
}

// dataDict pulled from plist    
NSDictionary *button1Dict = [dataDict objectForKey:@"button1"];
NSDictionary *button2Dict = [dataDict objectForKey:@"button2"];
NSDictionary *button3Dict = [dataDict objectForKey:@"button3"];
NSDictionary *button4Dict = [dataDict objectForKey:@"button4"];
NSDictionary *button5Dict = [dataDict objectForKey:@"button5"];
NSDictionary *button6Dict = [dataDict objectForKey:@"button6"];

// selectedCatTag and selectedItemTag for each button are alloc and init in viewDidLoad
button1SelectedCatTag = (NSUInteger *)[[button1Dict objectForKey:@"selectedCatTag"] integerValue];
button2SelectedCatTag = (NSUInteger *)[[button2Dict objectForKey:@"selectedCatTag"] integerValue];
button3SelectedCatTag = (NSUInteger *)[[button3Dict objectForKey:@"selectedCatTag"] integerValue];

UIButton *button1 = (UIButton *)[cell viewWithTag:1];
UIButton *button2 = (UIButton *)[cell viewWithTag:2];
UIButton *button3 = (UIButton *)[cell viewWithTag:3];
UIButton *button4 = (UIButton *)[cell viewWithTag:4];
UIButton *button5 = (UIButton *)[cell viewWithTag:5];

CGFloat kImageSquareSideLength = 100.0;

    [button6 addTarget:self action:@selector(button6Pressed:) forControlEvents:UIControlEventTouchUpInside];
} 

return cell;

}

//all other button actions are identical to button1Pressed
- (IBAction)button1Pressed:(id)sender
{
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
SelectedItemViewController *destVC = [storyboard instantiateViewControllerWithIdentifier:@"SelectedItemViewController"];

destVC.selectedOutfitDict = @"DiscoverOutfits";
destVC.selectedCatTag = (int *)button1SelectedCatTag;
destVC.selectedItemTag = (int *)button1SelectedItemTag;

[self presentViewController:destVC animated:NO completion:nil];
}

Answer 1

yes you can get particular cell from which button is taped. write in your IBAction method and you will get particular cell taped button in indexPath object

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

hope this will help
