How to make two or more strings in UILabel text point to different links

Question

I have a UILabel which shows the String. I need to change the color of the particular texts in the UILabel and when clicking on those texts it should open two different links in a webview. How to achieve this: The following code i have written:

  - (void)viewDidLoad {
  [super viewDidLoad];
  // Do any additional setup after loading the view, typically from a nib.
  NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:@"This is Yahoo and Google" attributes:nil];
  [attributedString addAttribute: NSForegroundColorAttributeName
                    value: [UIColor redColor]
                    range: NSMakeRange(8,5)];


  [attributedString addAttribute: NSFontAttributeName
                    value:  [UIFont fontWithName:@"Helvetica" size:15]
                    range: NSMakeRange(8,5)];

  [attributedString addAttribute: NSFontAttributeName
                    value:  [UIFont fontWithName:@"Didot" size:24]
                    range: NSMakeRange(18,6)];

  self.linkLabel.attributedText  = attributedString;

}

Now i want when the user clicks on google it should open google.com and when the user taps Yahoo it should open yahoo.com. how is ti possible?

try to change to UITextView and it should use the following

    let verbiage = links.text! // UITextView text
    let attributes = NSMutableAttributedString(string: verbiage)

    let googleRange = (verbiage as NSString).range(of: "Google")
    let yahooRange = (verbiage as NSString).range(of: "Yahoo")

    attributes.addAttribute(NSLinkAttributeName, value: "https://www.google.com", range: googleRange)
    attributes.addAttribute(NSLinkAttributeName, value: "https://www.yahoo.com", range: yahooRange)

    let linkAttributes: [String : Any] = [
        NSForegroundColorAttributeName: UIColor.red,
        NSUnderlineColorAttributeName: UIColor.clear,
        NSUnderlineStyleAttributeName: NSUnderlineStyle.styleNone.rawValue]

    links.linkTextAttributes = linkAttributes
    links.attributedText = attributes

Do not forget set Scrolling Enabled to false and Editable to false in order to get UITextView similar to UILabel

Use below line to add link to your text before assigning attributedString

 [attributedString addAttribute:NSLinkAttributeName value:[NSUrl urlwithString@"https://www.google.com"] range:NSMakeRange(18,6)];

Similarly you can do for other strings as well.
