How to make URL/Phone-clickable UILabel?

Question

You can use a UITextView and select Detection for Links, Phone Numbers and other things in the inspector.

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

Objective-C:

yourTextView.editable = NO;
yourTextView.dataDetectorTypes = UIDataDetectorTypeAll;

Swift:

yourTextView.editable = false; 
yourTextView.dataDetectorTypes = UIDataDetectorTypes.All;

This will detect links automatically.

See the documentation for details.

https://github.com/mattt/TTTAttributedLabel

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

You can make a custom UIButton and setText what ever you want and add a method with that.

UIButton *sampleButton = [UIButton buttonWithType:UIButtonTypeCustom];
[sampleButton setFrame:CGRectMake(kLeftMargin, 10, self.view.bounds.size.width - kLeftMargin - kRightMargin, 52)];
[sampleButton setTitle:@"URL Text" forState:UIControlStateNormal];
[sampleButton setFont:[UIFont boldSystemFontOfSize:20]];


[sampleButton addTarget:self action:@selector(buttonPressed) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:sampleButton];


-(void)buttonPressed:(id)sender{
  // open url
}

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

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(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<ObjCBool>) in

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

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

}}

This class was made by reusing code from this answer. In order to make attributed strings check out this answer. And here you can find how to make phone urls.

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.
