将UITapGestureRecognizer添加到UITextView而不阻止textView触摸

我如何添加一个UITapGestureRecognizer到一个UITextView，但仍然有触及通过UITextView 正常 ？

目前只要我添加一个自定义的手势到我的textView它会阻止UITextView的默认动作，如定位光标。

 var tapTerm:UITapGestureRecognizer = UITapGestureRecognizer() override func viewDidLoad() { tapTerm = UITapGestureRecognizer(target: self, action: "tapTextView:") textView.addGestureRecognizer(tapTerm) } func tapTextView(sender:UITapGestureRecognizer) { println("tapped term – but blocking the tap for textView :-/") … } 

我怎样才能处理水龙头，但像光标定位保持任何textView行为？

Answer 1

要做到这一点，使您的视图控制器采用UIGestureRecognizerDelegate和覆盖应该同时识别手势识别方法，如：

 override func viewDidLoad() { tapTerm = UITapGestureRecognizer(target: self, action: "tapTextView:") tapTerm.delegate = self textView.addGestureRecognizer(tapTerm) } func gestureRecognizer(gestureRecognizer: UIGestureRecognizer, shouldRecognizeSimultaneouslyWithGestureRecognizer otherGestureRecognizer: UIGestureRecognizer) -> Bool { return true }

如果有人来到这里寻找@Zell B.在Objective C中的答案，这里是代码：

 - (void)viewDidLoad { [super viewDidLoad]; UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(textViewTapped:)]; tap.delegate = self; tap.numberOfTapsRequired = 1; [self.textView addGestureRecognizer:tap]; } - (void)textViewTapped:(UITapGestureRecognizer *)tap { //DO SOMTHING } #pragma mark - Gesture recognizer delegate - (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer { return YES; } 

PS：不要忘记<UIGestureRecognizerDelegate>
