我有这个使用“ShouldInteractWith”方法的自定义 UITextView：
class StudyText: UITextView, UITextViewDelegate {
func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange, interaction: UITextItemInteraction) -> Bool {
print(URL)
return false
}
}
struct ClickableText: UIViewRepresentable {
@Binding var text: NSMutableAttributedString
func makeUIView(context: Context) -> StudyText {
let view = StudyText()
view.dataDetectorTypes = .all
view.isEditable = false
view.isSelectable = true
view.delegate = view
view.isUserInteractionEnabled = true
return view
}
func updateUIView(_ uiView: StudyText, context: Context) {
uiView.attributedText = text
}
}
我有这个扩展来设置属性文本的链接：
extension NSMutableAttributedString {
func apply(link: String, subString: String) {
if let range = self.string.range(of: subString) {
self.apply(link: link, onRange: NSRange(range, in: self.string))
}
}
private func apply(link: String, onRange: NSRange) {
self.addAttributes([NSAttributedString.Key.link: link], range: onRange)
}
}
我创建了这个布局：
struct contentView: View {
@State text: NSMutableAttributedString = NSMutableAttributedString(string: "")
var body: some View {
VStack {
ClickableText(text: self.$text)
}
.onAppear{
let myText = "Click Me!"
let attributedString = NSMutableAttributedString(string: myText)
attributedString.apply(link: "Soeme random link", subString: myText)
self.text = attributedString
}
}
}
当我单击文本视图时，它不会向控制台打印任何内容，有时它会崩溃。我怎样才能解决这个问题？
