Usage

To start using TTTAttributedLabel, follow these steps:

    2. let label = TTTAttributedLabel(frame: CGRect(x: 0, y: 0, width: 200, height: 50))
  2. Set the attributed text for the label:
    3. label.attributedText = NSAttributedString(string: "Hello, World!")

  • enabledTextCheckingTypes: Specify the types of data to detect (e.g., phone numbers, addresses, etc.).

Examples

Here are a few examples to showcase the capabilities of TTTAttributedLabel:

let label = TTTAttributedLabel(frame: CGRect(x: 0, y: 0, width: 200, height: 50))
let text = "This is a sample text with a link. Visit our website at www.example.com."
let attributedText = NSMutableAttributedString(string: text)
let linkRange = (text as NSString).range(of: "www.example.com")
let linkAttributes: [NSAttributedString.Key: Any] = [
    .foregroundColor: UIColor.blue,
    .underlineStyle: NSUnderlineStyle.single.rawValue
]
attributedText.addAttributes(linkAttributes, range: linkRange)
label.attributedText = attributedText
label.addLink(to: URL(string: "http://www.example.com"), with: linkRange)

This code snippet creates a label with a sample text containing a link. The link is customized with blue color and underlined. Tapping the link will open the specified website.
