What is it?

Gatti is a library for moving cursor between text fields in an elegant style. It is especially well suited for better user interactions such as on the auth screens.

Here is a quick example of how you can transform your screens!

Appearence

The library has a default appearance. So, when you don't specify the speed or color properties, Gatti uses the default values.

Default values:

• speed: TimeInterval
  • default: 0.55
• color: UIColor?
  • default: .none (textField.tintColor by default)

How to use

 override func viewDidLoad() {
     super.viewDidLoad()
    
     // Attach cursor to the UIViewController
     Gatti.attach(to: self)
     
     // Attach cursor with delegate
     Gatti.attach(to: self, delegate: self)
     
     // Attach cursor only for some fields
     Gatti.attach(to: self, textFields: [UITextField])
     
     // Update cursor moving speed and set defaule color for all the text fields
     Gatti.update(to: self, speed: 0.8, color: .red)
     
     ...
     
     // Detach cursor from the screen
     Gatti.detach(from: self)
 }

Delegate

extension ViewController: UITextFieldDelegate, UITextFieldCaretDelegate {
    
    func caretWillAttach(to textField: UITextField) {
        // Will attach to the UITextField
    }
    
    func caretDidDetach(from textField: UITextField) {
        // Did detach from the UITextField
    }
   
    func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
        // Handle UITextField delegate methods
        return true
    }
}
