问题描述
如何将 UITapGestureRecognizer 添加到UITextView，但仍然可以触及到 UITextView normal ？
How can I add a UITapGestureRecognizer to a UITextView but still have the touches getting through to the UITextView as normal?
目前，只要我向textView添加自定义手势，它就会阻止点击UITextView默认操作，例如定位光标。
Currently as soon as I add a custom gesture to my textView it blocks the tap for UITextView default actions like positioning the cursor.
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 :-/")
…
}
我如何处理点击但保持像光标定位一样的textView行为？
How can I process taps but keep any textView behaviour like cursor positioning as is?
推荐答案
要做到这一点，视图控制器采用UIGestureRecognizerDelegate并覆盖shoul d同时识别手势识别器方法，如：
To do that make your view controller adopt to UIGestureRecognizerDelegate and override should recognize simultaneously with gesture recognizer method like:
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
}
