With CocoaPods

CocoaPods is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries in your projects. To install with cocoaPods, follow the "Get Started" section on CocoaPods.

Podfile

platform :ios, '6.0'
pod 'LGFilterView', '~> 1.0.0'

With Carthage

Carthage is a lightweight dependency manager for Swift and Objective-C. It leverages CocoaTouch modules and is less invasive than CocoaPods. To install with carthage, follow the instruction on Carthage.

Cartfile
