How to solve this challenge?

How do I solve this challenge? I tried the code below, but without success

UITapGestureRecognizer* tripleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(test)]; tripleTap.numberOfTapsRequired = 3; [self addGestureRecognizer:tripleTap];

your code is technically correct. However all the challenge asks you to do is alloc and init it and set the number of taps. It does not ask you to alloc and initWithTarget: action:, then set the taps, then add the gesture recognizer to the view Controller.

so call alloc and init on your variable (just use [[UITapGestureRecognizer alloc] init];) , and then set the number of taps. Thats it.
