Implementing a UI for cropping image could be a headache in iOS. Well, you might find a library which could work but it sometimes introduces tons of unnecessary features, for example, image filter, or, it might have a lot of unnecessary UI that makes it impossible to customize. However, EasyCrop is just a very very simple library. It only provides a subclass of UIView which helps you crop an image. It's just that simple.
To run the example project, clone the repo, and run pod install from the Example directory first.
EasyCrop is available through CocoaPods. To install it, simply add the following line to your Podfile:
pod 'EasyCrop'nilinyi, nilinyi@gmail.com
