Latch

Hackathon: Producthunt Hackathon

Date: November 25, 2014

Placed: N/A

Coding Time: 12 hours

Team Members: 2

Description: Easily use Passcode and Touch ID authentication!

Install

1) Copy Framework folder into your project

2) Change Latch.LTPasscode.xib to <module>.LTPasscode.xib

Configure (Example)

1) Create Latch in View Controller

self.latch = Latch()
self.latch.delegate = self // Make sure to add LatchDelegate to Class
self.latch.parentController = self

2) Add Delegate Methods

func latchGranted() {
    println("access granged")
}

func latchSet() {
    println("passcode set")
}

func latchDenied(reason: LatchError) {
    println(reason.hashValue)
}

3) Customize Messages (Optional)

self.latch.touchReason = "We need to make sure it's you!"
self.latch.passcodeInstruction = "Enter Passcode"

4) Customize Theme (Optional)

self.latch.passcodeTheme.logo = UIImage(named: "Logo")!
self.latch.passcodeTheme.logoTint = nil
self.latch.passcodeTheme.instructions = UIColor(red:0.96, green:0.33, blue:0.24, alpha:1)

//Passcode theme options
struct LTPasscodeTheme {
    var logo: UIImage = UIImage(named: "Latch")!
    var logoTint: UIColor! = UIColor(red:0.12, green:0.67, blue:0.95, alpha:1)
    var logoErrorTint: UIColor = UIColor.redColor()

    var instructions: UIColor = UIColor(red:0.01, green:0.66, blue:0.96, alpha:1)
    var instructionsError: UIColor = UIColor.redColor()

    var background: UIColor = UIColor.whiteColor()
    var statusBar: LTPasscodeStatusBar = .Light

    var keyPadBackground: UIColor = UIColor.whiteColor()
    var keyPadBorder: UIColor = UIColor(red:0.01, green:0.66, blue:0.96, alpha:1)

    var keyPadTouchBackground: UIColor = UIColor(red:0.01, green:0.66, blue:0.96, alpha:1)
    var keyPadTouchBorder: UIColor = UIColor.whiteColor()

    var bubbleBackground: UIColor = UIColor.whiteColor()
    var bubbleColor: UIColor = UIColor(red:0.01, green:0.66, blue:0.96, alpha:1)

    var bubbleActiveBackground: UIColor = UIColor(red:0.01, green:0.66, blue:0.96, alpha:1)
    var bubbleActiveColor: UIColor = UIColor(red:0.01, green:0.66, blue:0.96, alpha:1)

    var bubbleErrorBackground: UIColor = UIColor.redColor()
    var bubbleErrorColor: UIColor = UIColor.redColor()
}

5) Turn On/Off Touch ID & Passcode (Optional)

self.latch.enableTouch = true // True by default 
self.latch.enablePasscode = true // True by default 

Usage

Set Passcode: self.latch.updatePasscode()

Remove Passcode: self.latch.removePasscode()

Authorize User: self.latch.authorize()

Thanks for looking at our small docs. Please use carefully, this was built in less than 12 hours and is no where near perfect. Thanks:)
