向NSAttributedString添加常规操作？

问题描述

我只是想在我的UILabel中使用NSAttributedString添加一个objetive-c动作来调用某个范围。

I simply want to add an objetive-c action to be called upon a tap on a certain range in my UILabel using NSAttributedString.

但我不知道怎么做。我不想打开网址，我只想打电话给方法。

But I don't know how to do it. I don't want to open a URL, I just wanna to call a method.

谢谢

推荐答案

您可以使用NSLinkAttributeName本身来实现此目的。使用如下所示的属性字符串并将其设置为UITextView的文本。

You can use NSLinkAttributeName itself to achieve this. Use an attributed string as shown below and set it as the text of a UITextView.

 NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc]initWithString:termsString];
        [attributedString addAttribute:NSLinkAttributeName value:url range:range];
[myTextView setAttributedText:attributedString];

然后覆盖UITextView委托方法：

And then override the UITextView delegate method:

-(BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange{

// Call your method here.
return YES;
}

别忘了设置textView的委托！

Dont forget to set the delegate of your textView!
