UILabel drop-in replacement supporting Hashtags (#), Mentions (@), URLs (http://) and custom regex patterns, written in Swift
UILabel
drop-in replacementrt ActiveLabel
label = ActiveLabel()
l.numberOfLines = 0
l.enabledTypes = [.mention, .hashtag, .url]
l.text = "This is a post with #hashtags and a @userhandle."
l.textColor = .black
l.handleHashtagTap { hashtag in
int("Success. You just tapped the \(hashtag) hashtag")
let customType = ActiveType.custom(pattern: "\\swith\\b") //Regex that looks for "with"
label.enabledTypes = [.mention, .hashtag, .url, customType]
label.customColor[customType] = UIColor.purple
label.customSelectedColor[customType] = UIColor.green
label.handleCustomTap(for: customType) { element in
print("Custom type tapped: \(element)")
}
By default, an ActiveLabel instance has the following configuration
label.enabledTypes = [.mention, .hashtag, .url]
But feel free to enable/disable to fit your requirements
When using ActiveLabel, it is recommended to use the customize(block:)
method to customize it. The reason is that ActiveLabel 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 ActiveLabel is only going to refresh the textContainer once.
Example:
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) }
}
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.

Before writing ActiveLabel
we've tried a lot of the following alternatives but weren't quite satisfied with the quality level or ease of usage, so we decided to contribute our own solution.
