Add a regular action to an NSAttributedString?

问题

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

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

Thanks

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];

And then override the UITextView delegate method:

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

// Call your method here.
return YES;
}

Dont forget to set the delegate of your textView!

Also, you can just make a simple transparent UITouch like control on top it. It means that you need to fake it.
