CocoaPods

pod "GPassword"

or you can drag Source folder into your project.

First custom UI style, here is what you need:

GPassword.config { (options) in
    options.connectLineStart = .border
    options.normalstyle = .innerFill
    options.isDrawTriangle = true
    options.matrixNum = 3
}

then you can use Box.swift or add it to a UIViewController

fileprivate lazy var passwordBox: Box = {
    let box = Box(frame: CGRect(x: 50, y: 200, width: GWidth - 2 * 50, height: 400))
    box.delegate = self
    return box
}()

then you need to achieve two delegate methods, you should write business logics in them, sendTouchPoint can send out complete password and touchesEnded can deal business logics according to type(setting/verify/modify)

extension PasswordViewController: EventDelegate {
    func sendTouchPoint(with tag: String) {
        password += tag
        // get complete password
    }
    
    func touchesEnded() {
        // write business logics according to type
    }
}

more informations you can see PasswordViewController.swift in demo project, I write an example.
