I have the following code snippets

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {

    UITouch *touch = [touches anyObject];
    NSUInteger numberTaps = [touch tapCount];

    // Tapping
    if (numberTaps > 0) {
       // do something
    }

...

The above code basically detects a single tap on a small image (width = 18 and height = 36). It works 90% of the time detecting a single tap.

But it sometime misses it (randomly). I have to tap several times before it picks up the single tap.

What did I do wrong or miss so I could consistently detect the single tap 100%?

Thanks in advance for your help.
