IOS -TextView 委托(delegate)未在页面容器 View 中调用

Question

我在 PageController 的页面容器 View 中使用了一个 textView。这是我的代码-

class pageContentView: UIViewController,UITextViewDelegate {

@IBOutlet weak var lblDetailTextt: UILabel!
@IBOutlet weak var lblDetailHeading: UILabel!
@IBOutlet weak var txtvieww: UITextView!

var strHeadingText = String()
var strText = String()
 var itemIndex: Int = 0

override func viewWillAppear(_ animated: Bool) {
    txtvieww.delegate = self
}
override func viewDidLoad() {
    super.viewDidLoad()
    //lblDetailTextt.text = strText

    lblDetailHeading.text = strHeadingText
     //self.lblDetailTextt.attributedText = self.stringFromHtml(string: strText)
    txtvieww.attributedText = self.stringFromHtml(string: strText)


    // Do any additional setup after loading the view.
}

func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange, interaction: UITextItemInteraction) -> Bool {
    print("enabledd")
    return true
}

但是Delegate方法没有调用。有谁知道如何调用它吗？

检查您的 TextView 并确保其属性设置正确

"Links in text views are interactive only if the text view is selectable but noneditable. That is, if the value of the UITextViewselectable property is YES and the editable property is NO."

试试这个:

txtvieww.isEditable = false
txtvieww.isSelectable = true
