PEPhotoCropEditor

PEPhotoCropEditor is an iOS image-cropping library modeled after the editing interface of Apple's Photos app. It provides both a complete crop view controller and a reusable crop view for embedding inside custom interfaces. Users can reposition and resize the crop area while using pinch gestures to zoom the image. Rotation gestures allow photos to be adjusted before the final crop is produced. The library works on both iPhone and iPad and supports changing device orientations. Developers can specify crop rectangles programmatically, preserve a fixed aspect ratio, or reset the editor to the original image state. Cropped UIImage results can be retrieved through a delegate or directly from the crop view.
