I know that this is a very commonly asked question, but all of the answers on every website don't work! If you still don't know what I mean, then maybe this line of code will help you understand.

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    UITouch *touch = [[event allTouches] anyObject];
    CGPoint location = [touch locationInView:self.view];
    if (touch.view == nextbutton)
        [self performSelector:@selector(next)];
    if (touch.view == prevbutton)
        [self performSelector:@selector(previous)];
    if (touch.view == moreoptionsbutton)
        [self performSelector:@selector(moresettings)];
}

It doesn't do anything when you touch nextbutton, prevbutton, and more optionsbutton, which are UIImageViews by the way. I have also tried using isEqual: instead of ==, but that hasn't worked out either. Any suggestions?
