In order to utilize UILongPressGestureRecognizer you must set the minimumPressDuration property. This specifies how long to wait until your gesture recognizer is fired. For example

UILongPressGestureRecognizer *longPress = [[[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPress:)] autorelease];
longPress.minimumPressDuration = 2.0f;
[self.button addGestureRecognizer:longPress];

- (void)longPress:(UILongPressGestureRecognizer*)gesture {
    if ( gesture.state == UIGestureRecognizerStateEnded ) {
         NSLog(@"Long Press");
    }
}
