I created a custom UItableviewcell
added a button into its initWithStyle area:
favoriteButton = [[UIButton buttonWithType:UIButtonTypeRoundedRect] retain];
favoriteButton.backgroundColor = [UIColor clearColor];
[favoriteButton setTitle:@"Play" forState:UIControlStateNormal];
[favoriteButton addTarget:self action:@selector(favoriteClick:) forControlEvents:UIControlEventTouchUpInside];
favoriteButton.center = self.center;
set its frame and layout in:
- (void)layoutSubviews {
[super layoutSubviews];
CGRect contentRect = self.contentView.bounds;
CGFloat boundsX = contentRect.origin.x;
CGRect frame;
frame = CGRectMake(boundsX+200, 44, 40, 40);
favoriteButton.frame = frame;
}
and then in my tableviewcontroller.m file I use that tableviewcell and have the user click tap to go to the action within that tableviewcontroller.m code
-(void)favoriteClick:(id)sender// forEvent:(UIEvent*)event
{
NSLog(@"click");
}
however when i tap the button I get an unhandled exception:

terminate called after throwing an instance of 'NSException'
I dont see what Im doing wrong here...
Try returning IBAction
instead of void
on your selector, and put the selector in the ProgramGuideCell
instead of tableviewcontroller.
-(IBAction)favoriteClick:(id)sender// forEvent:(UIEvent*)event
{
NSLog(@"click");
}
