Use <code>UITextView</code> instead of <code>UILabel</code> and it has a property to convert your text to hyperlink.

<h3>Objective-C:</h3>

<pre><code>yourTextView.editable = NO;
yourTextView.dataDetectorTypes = UIDataDetectorTypeAll;
</code></pre>

<h3>Swift:</h3>

<pre><code>yourTextView.editable = false; 
yourTextView.dataDetectorTypes = UIDataDetectorTypes.All;
</code></pre>

This will detect links automatically.

See <a href="https://developer.apple.com/documentation/uikit/uidatadetectortypes" rel="noreferrer">the documentation</a> for details.

That's definitely what you need. You can also apply attributes for your label, like underline, and apply different colors to it. Just check the instructions for clickable urls.

Mainly, you do something like the following:

<pre><code>NSRange range = [label.text rangeOfString:@"me"];
[label addLinkToURL:[NSURL URLWithString:@"http://github.com/mattt/"] withRange:range]; // Embedding a custom link in a substring

If you want this to be handled by UILabel and not UITextView, you can make UILabel subclass, like this one:

<pre><code>class LinkedLabel: UILabel {

fileprivate let textContainer = NSTextContainer(size: CGSize.zero)
fileprivate var textStorage: NSTextStorage?


override init(frame aRect:CGRect){

 self.initialize()
}

required init?(coder aDecoder: NSCoder) {
 super.init(coder: aDecoder)
 self.initialize()
}

func initialize(){

 let tap = UITapGestureRecognizer(target: self, action: #selector(LinkedLabel.handleTapOnLabel))
 self.isUserInteractionEnabled = true
 self.addGestureRecognizer(tap)
}

override var attributedText: NSAttributedString?{
 didSet{
 if let _attributedText = attributedText{
 self.textStorage = NSTextStorage(attributedString: _attributedText)

 self.layoutManager.addTextContainer(self.textContainer)
 self.textStorage?.addLayoutManager(self.layoutManager)

 self.textContainer.lineFragmentPadding = 0.0;
 self.textContainer.lineBreakMode = self.lineBreakMode;
 self.textContainer.maximumNumberOfLines = self.numberOfLines;
 }

 }
}

func handleTapOnLabel(tapGesture:UITapGestureRecognizer){

 let locationOfTouchInLabel = tapGesture.location(in: tapGesture.view)
 let labelSize = tapGesture.view?.bounds.size
 let textBoundingBox = self.layoutManager.usedRect(for: self.textContainer)
 let textContainerOffset = CGPoint(x: ((labelSize?.width)! - textBoundingBox.size.width) * 0.5 - textBoundingBox.origin.x, y: ((labelSize?.height)! - textBoundingBox.size.height) * 0.5 - textBoundingBox.origin.y)

 let locationOfTouchInTextContainer = CGPoint(x: locationOfTouchInLabel.x - textContainerOffset.x, y: locationOfTouchInLabel.y - textContainerOffset.y)
 let indexOfCharacter = self.layoutManager.characterIndex(for: locationOfTouchInTextContainer, in: self.textContainer, fractionOfDistanceBetweenInsertionPoints: nil)


 self.attributedText?.enumerateAttribute(NSLinkAttributeName, in: NSMakeRange(0, (self.attributedText?.length)!), options: NSAttributedString.EnumerationOptions(rawValue: UInt(0)), using:{
 (attrs: Any?, range: NSRange, stop: UnsafeMutablePointer&lt;ObjCBool&gt;) in

 if NSLocationInRange(indexOfCharacter, range){
 if let _attrs = attrs{

 UIApplication.shared.openURL(URL(string: _attrs as! String)!)

}}
