Columbina’s MaskedUITextField

A UITextField with fully customizable formatter.

Quick start

1. Import the module

import MaskedUITextField

2. Define a MaskedFormatter

Use the MaskedFormatter framework in order to create a mask:

let mask = "##/$-@@"

let rules = [
    MaskedFormatter.Rule(maskCharacter: "#", validation: { $0.isNumber }),
    MaskedFormatter.Rule(maskCharacter: "$", validation: { $0.isLetter }),
    MaskedFormatter.Rule(maskCharacter: "@", validation: { (Int(String($0)) ?? 0) >= 5 })
]

let maskedFormatter = MaskedFormatter(mask: mask, rules: rules)

3. Instantiate a MaskedUITextField

let textField = MaskedUITextField(formatter: maskedFormatter)

Alternatively:

let textField = MaskedUITextField()
textField.formatter = maskedFormatter
