SPPatternLock is a powerful tool used for implementing the iOS Pattern lock UI. This tool is an open-source library that provides developers with the ability to integrate the pattern lock feature into their iOS applications. The pattern lock feature is popular in securing devices, applications and sensitive data by connecting dots in a specific pattern centrally controlled by the user. This page can guide users on how to accomplish the installation, configuration, usage, and customization of the tool.
Installation
You can install SPPatternLock through CocoaPods, an application level dependency manager for Swift and Objective-C Cocoa projects. To achieve that, follow these steps:
- Open terminal and navigate to your project directory.
- Type
pod init
in the terminal to create a Podfile. - Open the Podfile via terminal using the command
open -a Xcode Podfile
. - Under the
# Pods for <Your_Project_Name>
, addpod 'SPPatternLock'
. - Save and close the file.
- Install the pod via terminal with the command
pod install
. - Open the newly created .xcworkspace file, which should now include SPPatternLock.
Configuration
After the installation, you need to import the module on the ViewController where you want to use it. You can do this by adding import SPPatternLock
at the beginning of the file. The next step is to configure the pattern lock view according to your requirements. This can include setting the grid size, pattern tintColor, error tintColor, inner circle color, etc.
Usage
To use the Pattern Lock, your ViewController should conform with the SPPatternLock delegate. Within the delegate methods, you can handle different actions. For example, patternDidSet and patternDidComplete. In patternDidSet, you can store the initial pattern set by the user. While in patternDidComplete, you can compare the completed pattern with the set pattern to authenticate the user or show error message accordingly.
Customization
SPPatternLock provides great customization options to blend smoothly with your app design. You can adjust the UI attributes like node size, node distance, line width, error animation duration, etc. All these settings can be easily configured with the available methods and properties.
