Question

I don’t know why this is happening, but I get this error:

-[__NSArrayM section]: unrecognized selector sent to instance 0x7e53b70 2012-01-07 15:35:44.108 Timely1[51661:15203] * Terminating
app due to uncaught exception ‘NSInvalidArgumentException’, reason:
‘-[__NSArrayM section]: unrecognized selector sent to instance
0x7e53b70’

when handleTouch is activated. Here is my code for adding the image and tap gesture.

[cell.imageView setUserInteractionEnabled:YES];
[cell.imageView setImage:[UIImage imageNamed:@"checkbox.PNG"]];

UITapGestureRecognizer *tapped = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTouch:)];
tapped.numberOfTapsRequired = 1;
[cell.imageView addGestureRecognizer:tapped];   
[tapped release];

and then my code for handling the touch:

-(void)handleTouch:(UITapGestureRecognizer *)gesture
{
    NSIndexPath *indexPath = [NSIndexPath indexPathForRow:[array count] inSection:1];
    UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];

    [cell.imageView setImage:[UIImage imageNamed:@"checkbox_checked.PNG"]];
    [self.tableView reloadRowsAtIndexPaths:[NSArray arrayWithObject:array] withRowAnimation:UITableViewRowAnimationFade];
}

UPDATE: How about if I wanted to uncheck it (like toggling it) does anybody know how to do that?

Answer 1

In your handleTouch method i think you could use:

UIImageView *cellImageView=(UIImageView *)gesture.view;
