Answer 1

Use this i liked it so much since creates link with blue color to particular text only not on whole label text: FRHyperLabel

To do:

1. Download from above link and copy FRHyperLabel.h, FRHyperLabel.m to your project.

2. Drag drop UILabel in your Storyboard and define custom class name to FRHyperLabel in identify inspector as shown in image.

3. Connect your UILabel from storyboard to your viewController.h file

@property (weak, nonatomic) IBOutlet FRHyperLabel *label;

4. Now in your viewController.m file add following code.

`NSString *string = @"By uploading I agree to the Terms of Use"; NSDictionary *attributes = @{NSFontAttributeName: [UIFont preferredFontForTextStyle:UIFontTextStyleHeadline]};

_label.attributedText = [[NSAttributedString alloc]initWithString:string attributes:attributes];
[_label setFont:[_label.font fontWithSize:13.0]];

[_label setLinkForSubstring:@"Terms of Use" withLinkHandler:^(FRHyperLabel *label, NSString *substring){
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://www.google.com"]];
}];`

5. And run it.

Use UITextView instead of UILabel and it has a property to convert your text to hyperlink

Swift code:

yourTextView.editable = false
yourTextView.dataDetectorTypes = UIDataDetectorTypes.All
//or
yourTextView.dataDetectorTypes = UIDataDetectorTypes.PhoneNumber
//or
yourTextView.dataDetectorTypes = UIDataDetectorTypes.Link

Swift 4.2, Xcode 9.3 version

class LinkedLabel: UILabel {

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


    override init(frame aRect:CGRect){
        super.init(frame: aRect)
        self.initialize()
    }

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

    func initialize(){

        let tap = UITapGestureRecognizer(target: self, action: #selector(self.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;
            }

        }
    }

    @objc 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(NSAttributedStringKey.link, in: NSMakeRange(0, (self.attributedText?.length)!), options: NSAttributedString.EnumerationOptions(rawValue: UInt(0)), using:{
            (attrs: Any?, range: NSRange, stop: UnsafeMutablePointer<ObjCBool>) in

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

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

    }}

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:

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