title: UIButton function with target nil doens´t get called?
body: <p>i´ve made lots of my own "CustomUIButton" in a for-loop in my viewcontroller. 
  In this "CustomUIButton"-class i´ve implemented an UIGestureRecognizer like this:</p>
  
  <pre><code>    (id)initWithFrame:(CGRect)frame 
      {
          self = [super initWithFrame:frame];
          if (self) {
  
      // custom things.
  
       UILongPressGestureRecognizer* longPress = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(handleLongPress:)];
              longPress.minimumPressDuration = 1.0;
              [self addGestureRecognizer:longPress];
              [longPress release];
      }
  }
  
      - (void) handleLongPress:(UILongPressGestureRecognizer*) recognizer{
  
          if (recognizer.state == UIGestureRecognizerStateEnded) {
              NSLog(@"Long press Ended");
          }
          else {
  
              NSLog(@"Long press detected.");
               // Do something
          }
      }
  </code></pre>
  
  <p>If i init the target with "self", my "handleLongPress"-function in this class will be called. It´s cool. If i init the target with "nil", it should check the parent viewcontroller, right? </p>
  
  <p>Any ideas why an additional function with the same name in my viewcontroller won´t be called? (For this test i´ve commented the "longpress"-function of the button-class out.)</p>
