Swift
Updated for Swift 3
Use with a textView.linkTextAttributes = [NSForegroundColorAttributeName: UIColor.green]
And in context:
let attributedString = NSMutableAttributedString(string: "This is an example by @marcelofabri_")
let linkRange = (attributedString.string as NSString).range(of: "@marcelofabri_")
attributedString.addAttribute(NSLinkAttributeName, value: "username://marcelofabri_", range: linkRange)
let linkAttributes: [String : Any] = [
NSForegroundColorAttributeName: UIColor.green,
NSUnderlineColorAttributeName: UIColor.lightGray,
NSUnderlineStyleAttributeName: NSUnderlineStyle.styleSingle.rawValue]
// textView is a UITextView
textView.linkTextAttributes = linkAttributes
textView.attributedText = attributedString
textView.delegate = self
Swift 4:
let linkAttributes: [String : Any] = [
NSAttributedStringKey.foregroundColor.rawValue: UIColor.green,
NSAttributedStringKey.underlineColor.rawValue: UIColor.lightGray,
NSAttributedStringKey.underlineStyle.rawValue: NSUnderlineStyle.styleSingle.rawValue]
Objective-C
Use with a textView.linkTextAttributes = @{NSForegroundColorAttributeName:[UIColor greenColor]};

And from this post:
NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:@"This is an example by @marcelofabri_"];
[attributedString addAttribute:NSLinkAttributeName
value:@"username://marcelofabri_"
range:[[attributedString string] rangeOfString:@"@marcelofabri_"]];
NSDictionary *linkAttributes = @{NSForegroundColorAttributeName: [UIColor greenColor],
NSUnderlineColorAttributeName: [UIColor lightGrayColor],
NSUnderlineStyleAttributeName: @(NSUnderlineStyleSingle)};
// assume that textView is a UITextView previously created (either by code or Interface Builder)
textView.linkTextAttributes = linkAttributes; // customizes the appearance of links
textView.attributedText = attributedString;
textView.delegate = self;
