An iOS pattern lock like Android authentication written in Swift.

OXPatternLock requires Swift 3.0 and Xcode 8

CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:

$ gem install cocoapods

To integrate OXPatternLock into your Xcode project using CocoaPods, specify it in your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '9.0'
use_frameworks!

target '<Your Target Name>' do
	# for stable release
    pod 'OXPatternLock'

    # for latest release
    pod 'OXPatternLock', :git => 'https://github.com/oxozle/OXPatternLock.git', :branch => 'master'
end

Then, run the following command:

$ pod install

Add OXPatternLock.swift to your project in Xcode

1. Create an implementation of the OXPatternLockDelegate protocol.

2. Add OXPatternLock to your Storyboard/xib file or create it manually.

3. For security reasons all processing you have to do manually. Receive callback from delegate with patternLock instance and track array. For example: if grid size equals 3 there are 9 track poins. So result track array will be array of integers from 0 to 8 like indexes in dots array.

func didPatternInput(patterLock: OXPatternLock, track: [Int]) {
  //store, check and update patter with track array
}

There is support for Interface Builder. All properties configurable from Interface Builder.

The locker can be customized by setting any of the following public properties before displaying the OXPatternLock. The defaults are shown below.
