How to Use

CustomMask takes a string and returns it with the matching pattern. Usualy, it is used inside the shouldChangeCharactersInRange method

Step 1 - Import

import TLCustomMask

Step 2 - Instantiate

var customMask = TLCustomMask()

Step 3 - Give it a pattern

customMask.formattingPattern = "$$.$$/$$-$"

Step 4 - Present

If you just want to format a string and present it to the user, do:

yourTextField.text = customMask.formatString(string: "1234567")

If you want real time formatting, do:

extension YourViewController: UITextFieldDelegate{
    func textField(_ textField: UITextField,
                   shouldChangeCharactersIn range: NSRange,
                   replacementString string: String) -> Bool {

        yourTextField.text = customMask.formatStringWithRange(range: range, string: string)

        return false
    }
}

Step 5 - Profit

Now you are ready to go!

Alternatively, you can instantiate it with a pattern already:

var customMask = TLCustomMask(formattingPattern: "$$$-$$")

Use $ for digits
Use * for characters [a-zA-Z]
