title: Why is my UIGestureRecognizer code not working?
body: <p>Why is the following code not working?</p>
  
  <pre><code>- (void)viewDidLoad
  {    
  
  UISwipeGestureRecognizer *oneFingerSwipeLeft = 
  [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(oneFingerSwipeLeft:)];
  [oneFingerSwipeLeft setDirection:UISwipeGestureRecognizerDirectionLeft];
  [[self view] addGestureRecognizer:oneFingerSwipeLeft];
  
  UISwipeGestureRecognizer *oneFingerSwipeRight = 
  [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(oneFingerSwipeRight:)];
  [oneFingerSwipeRight setDirection:UISwipeGestureRecognizerDirectionRight];
  [[self view] addGestureRecognizer:oneFingerSwipeRight];
  
  }
  
  - (void)oneFingerSwipeLeft:(UISwipeGestureRecognizer *)recognizer 
  { 
  CGPoint point = [recognizer locationInView:[self view]];
  NSLog(@"Swipe up - start location: %f,%f", point.x, point.y);
  }
  
  - (void)oneFingerSwipeRight:(UISwipeGestureRecognizer *)recognizer 
  { 
  CGPoint point = [recognizer locationInView:[self view]];
  NSLog(@"Swipe down - start location: %f,%f", point.x, point.y);
  }
  </code></pre>
  
  <p>Bear in mind that I have lots of layers (e.g. images, buttons and labels) in front of the bare view. Would this make a difference? How can I make the gestures be recognised on top of all these layers?</p>
  
  <p>Thanks!</p>
