将UITapGestureRecognizer添加到UITextView而不阻止textView触摸

Question

如何将a添加UITapGestureRecognizer到UITextView，但仍然UITextView像 往常 一样通过触摸？

当前，一旦我将自定义手势添加到textView中，它就会阻止对UITextView默认操作（如定位光标）的点击。

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 :-/")
…
}

我该如何处理点击，但保持所有textView行为（如光标定位）不变？

Answer 1

为此，使您的视图控制器采用UIGestureRecognizerDelegate，并且重写应与手势识别器方法同时识别，例如：

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
}
