Manual Installation

All of the necessary source and resource files for FasterVerificationCode are in FasterVerificationCode/Classes.

Examples

Using FasterVerificationCode is very easy and straightforward. Create a new UIView into your ViewController and insert into the Custom class field VerificationCodeView.

You can customize the appearance through the inspector tab and add your constraints.

Don't forget to:

• add a width constraint;
• declare it as placeholder (the view will resize at runtime following labels dimensions).

For a complete working example, check out the repo and run pod install into the project root.

Basic Implementation

@IBOutlet weak var verificationCodeView: VerificationCodeView!

override func viewDidLoad() {
    super.viewDidLoad()
    verificationCodeView.setLabelNumber(6)
    verificationCodeView.delegate = self
}

extension YourViewController: VerificationCodeViewDelegate {

    func verificationCodeInserted(_ text: String, isComplete: Bool) { 
    ...
    }
}

VerificationCodeViewDelegate

This delegate handle the insertion of the verification code with this two method:

verificationCodeInserted

func verificationCodeInserted(_ text: String, isComplete: Bool)

This method is mandatory and is called every time the textFieldShouldEndEditing method of the textfield is called. It gives you the current text and if the text was inserted totally.

You can check the correctness of the inserted code and show a visual feedback to the user

    if text == "123456" {
        .....
    } else {
        // The inserted code is wrong
        verificationCodeView.showError = true
    }

verificationCodeChanged (optional)

@objc optional func verificationCodeChanged()

This method is optional and is called only when the user is deleting a character. It should be implemented only if you are interested in error handling and you want to reset the border color to the default color you inserted.

    func verificationCodeChanged() {
        verificationCodeView.showError = false
    }
