UITextView打开链接

Question

我使用此代码：

var textView = UITextView(x: 10, y: 10, width: CardWidth - 20, height: placeholderHeight) //This is my custom initializer
textView.text = "dsfadsaf www.google.com"
textView.selectable = true
textView.dataDetectorTypes = UIDataDetectorTypes.Link
textView.delegate = self
addSubview(textView)

问题是链接需要长按手势才能打开。我希望它只需点击一下即可打开，就像在Facebook应用程序中一样。

Answer 1

以下示例仅适用于iOS 8 +

点按识别器：

lwpd.xsp.extsn.jar

回调：

let tapRecognizer = UITapGestureRecognizer(target: self, action: Selector("tappedTextView:"))
myTextView.addGestureRecognizer(tapRecognizer)
myTextView.selectable = true

Swift 3并且没有力量展开：

func tappedTextView(tapGesture: UIGestureRecognizer) {

    let textView = tapGesture.view as! UITextView
    let tapLocation = tapGesture.locationInView(textView)
    let textPosition = textView.closestPositionToPoint(tapLocation)
    let attr: NSDictionary = textView.textStylingAtPosition(textPosition, inDirection: UITextStorageDirection.Forward)

    if let url: NSURL = attr[NSLinkAttributeName] as? NSURL {
        UIApplication.sharedApplication().openURL(url)
    }

}
