To run the example project, clone the repo, and run pod install from the Example directory first.



RichLabel is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'RichLabel'


import RichLabel

let label = RichLabel()
label.numberOfLines = 0
label.enabledTypes = [.mention, .hashtag, .url, .email]
label.text = "This is a post with #hashtags and a @userhandle."
label.textColor = .black
label.handleHashtagTap { hashtag in
    print("Success. You just tapped the \(hashtag) hashtag")

Custom types

let customType = RichType.custom(pattern: "\\swith\\b") //Regex that looks for "with"
label.enabledTypes = [.mention, .hashtag, .url, .email, customType]
label.text = "This is a post with #hashtags and a @userhandle."
label.customColor[customType] = UIColor.purple
label.customSelectedColor[customType] =
label.handleCustomTap(for: customType) { element in
    print("Custom type tapped: \(element)")

Enable/disable highlighting

By default, an RichLabel instance has the following configuration

label.enabledTypes = [.mention, .hashtag, .url, .email]

But feel free to enable/disable to fit your requirements

Batched customization

When using RichLabel, it is recommended to use the customize(block:) method to customize it. The reason is that RichLabel is reacting to each property that you set. So if you set 3 properties, the textContainer is refreshed 3 times.

When using customize(block:), you can group all the customizations on the label, that way RichLabel is only going to refresh the textContainer once.


label.customize { label in
    label.text = "This is a post with #multiple #hashtags and a @userhandle."
    label.textColor = UIColor(red: 102.0/255, green: 117.0/255, blue: 127.0/255, alpha: 1)
    label.hashtagColor = UIColor(red: 85.0/255, green: 172.0/255, blue: 238.0/255, alpha: 1)
    label.mentionColor = UIColor(red: 238.0/255, green: 85.0/255, blue: 96.0/255, alpha: 1)
    label.URLColor = UIColor(red: 85.0/255, green: 238.0/255, blue: 151.0/255, alpha: 1)
    label.handleMentionTap { self.alert("Mention", message: $0) }
    label.handleHashtagTap { self.alert("Hashtag", message: $0) }
    label.handleURLTap { self.alert("URL", message: $0.absoluteString) }

Trim long urls

You have the possiblity to set the maximum lenght a url can have;

label.urlMaximumLength = 30

From now on, a url that’s bigger than that, will be trimmed. ->


mentionColor: UIColor = .blueColor()
mentionSelectedColor: UIColor?
hashtagColor: UIColor = .blueColor()
hashtagSelectedColor: UIColor?
URLColor: UIColor = .blueColor()
URLSelectedColor: UIColor?
customColor: [RichType : UIColor]
customSelectedColor: [RichType : UIColor]
lineSpacing: Float?
handleMentionTap: (String) -> ()
label.handleMentionTap { userHandle in print("\(userHandle) tapped") }
handleHashtagTap: (String) -> ()
label.handleHashtagTap { hashtag in print("\(hashtag) tapped") }
handleURLTap: (NSURL) -> ()
label.handleURLTap { url in UIApplication.shared.openURL(url) }
handleEmailTap: (String) -> ()
label.handleEmailTap { email in print("\(email) tapped") }
handleCustomTap(for type: RichType, handler: (String) -> ())
label.handleCustomTap(for: customType) { element in print("\(element) tapped") }
handleOutsideTap: () -> ()
label.handleOutsideTap { print("OutsideTap tapped") }
filterHashtag: (String) -> Bool
label.filterHashtag { hashtag in validHashtags.contains(hashtag) }
filterMention: (String) -> Bool
label.filterMention { mention in validMentions.contains(mention) }
