I want to use attributed strings with NSLinkAttributeName
to create clickable links inside a UILabel
instance within my iOS 7 project, which is now finally possible without using external libraries.
NSURL *url = [NSURL URLWithString:@"http://www.google.com"];
NSDictionary *attr = [NSDictionary dictionaryWithObjectsAndKeys:
url, NSLinkAttributeName, nil];
Applying the attribute on a string displays the text as blue & underlined, but nothing happens on click/tap. User interaction is enabled for the label. Does anybody know how to do this? Thanks!
I can answer my own question now:
I am using UITextView
instead of UILabel
now. I have formatted the UITextView
to look and behave like my labels and added:
UITextView *textView = [[UITextView alloc] init];
textView.scrollEnabled = NO;
textView.editable = NO;
textView.textContainer.lineFragmentPadding = 0;
textView.textContainerInset = UIEdgeInsetsMake(0, 0, 0, 0);
textView.delegate = self;
Don't forget to set the delegate, you have to implement UITextViewDelegate
! Now we implement the delegate method:
- (BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)url inRange:(NSRange)characterRange
{
return YES;
}
This automatically opens the provided the NSURL
-instance from the attributed string in my question on click/tap.
Remember: This works on iOS 7 only, for legacy support you need external libraries
UPDATE:
Making the UITextView
s behave just like labels was a total mess in the end and i stumbled upon some hideous iOS-behaviours. I ended up using the TTTAttributedLabel library which is simply great and allowed me to use labels instead of UITextView
s.
