IPhone - detect UITableViewCell subheading touches

I am filling a UITableView with cells containing a subview UIImageView. I would like to detect strokes in the image, so I add a gesture recognizer to it as well. However, it causes nothing. Here is my code:

UIImageView *delete = [[UIImageView alloc] initWithFrame:CGRectMake(1.0, 8.0, 33.0, 33.0)];
delete.image = [UIImage imageNamed:@"Delete.png"];
delete.userInteractionEnabled = YES;
delete.contentMode = UIViewContentModeCenter;

UIGestureRecognizer *gesture = [[UIGestureRecognizer alloc] initWithTarget:self action:@selector(deleteTapped)];
gesture.delegate = self;

[delete addGestureRecognizer:gesture];
[self.cellView addSubview:delete];


Note. I technically add the image view to the container, which is then added to the cell itself hence [self.cellView addSubview:delete]

. But I had the exact same results adding the image to the cell directly.

According to this answer to a similar post, this is a known bug in iOS 5.0; the solution is to override the delegate method to force the gesture recognizer to start:

The fix is ​​to override -gestureRecognizerShouldBegin: in the gesture recognizer delegate and return YES. This bug should be fixed in a future iOS 5.x release. This is safe as long as you don't use the new copy / paste API for the UITableViewCell.

I tried this, but the delegate method was never called. I set a property delegate

(see above) and implemented <UIGestureRecognizerDelegate>

like this:

- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer
    NSLog(@"gesture delegate method called");
    return YES;


Does anyone have any ideas why this won't work anyway? Or is it possible that this status of this bug is in iOS 5.1?

try returning YES for this delegate method - (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer;

and if you want to detect tap action use UITapGestureRecognizer
