Features 

-------------------------------------------------

* Add an NSArray of specific CGPoints to a UIImageView. * Add a specific number of points. * Drag&Drop of the points. * Crops the UIImage in a UIImageView. * Respects aspect ratio. * ARC(Automatic Reference Counting) support.

Installation

-------------------------------------------------

 * Drag the *JBCroppableImageView*/*JBCroppableLayer* files into your project. * Add the CoreGraphics framework to your project.

Usage (see example Xcode project in /TestCroping)

-------------------------------------------------

to set up, initialize how you would a reular UIImageView:

-JBCroppableImageView *cropView = [[JBCroppableImageView alloc]

initWithImage:[UIImage imageNamed:”demo”]];

it will be initialized with four crop points. To add or subtract the number of

points:

[cropView addPoint];

[cropView removePoint];

to crop the imageView to the requested shape or to revert back to uncropped

state:

[cropView crop];

[cropView reverseCrop];
