陶手势法没有触发

Question

我正在尝试以编程方式添加手势，但messagesBucketTap方法不会打印日志

// 
control=[self.storyboard instantiateViewControllerWithIdentifier:@"ControlScene"];
control.view.frame = CGRectMake(0, 0,control.view.frame.size.width,60);
[self.view addSubview:control.view];
//
UITapGestureRecognizer *messagesTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(messagesBucketTap:)];
[messagesTap setDelegate:self];
[messagesTap setNumberOfTapsRequired:1];
[messagesTap setNumberOfTouchesRequired:2];
[control.view addGestureRecognizer:messagesTap];

- (void)messagesBucketTap:(UITapGestureRecognizer *)gestureRecognizer{
NSLog(@"ramy'");}
