我试图在可点击链接的UITextview中显示一个归因的字符串.我创建了一个简单的测试项目,看看我在哪里错了,仍然无法弄清楚.我尝试启用用户交互并设置了shouldInteractWithURLs委托方法,但仍然无法使用.这是我的代码(对于只包含textview的视图控制器)
@IBOutlet weak var textView: UITextView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view,typically from a nib.
let string = "Google"
let linkString = NSMutableAttributedString(string: string)
linkString.addAttribute(NSLinkAttributeName,value: NSURL(string: "https://www.google.com")!,range: NSMakeRange(0,string.characters.count))
linkString.addAttribute(NSFontAttributeName,value: UIFont(name: "HelveticaNeue",size: 25.0)!,string.characters.count))
textView.attributedText = linkString
textView.delegate = self
textView.selectable = true
textView.userInteractionEnabled = true
}
这里是我实现的委托方法：
func textViewShouldBeginEditing(textView: UITextView) -> Bool {
return false
}
func textView(textView: UITextView,shouldInteractWithURL URL: NSURL,inRange characterRange: NSRange) -> Bool {
return true
}
这还不行.我搜索了这个话题,没有任何帮助.非常感谢提前.
