A view controller for iOS that allows users to crop portions of UIImage objects
What is TOCropViewController?
TOCropViewController is an open-source UIViewController subclass to crop out sections of UIImage objects, as well as perform basic rotations. It is excellent for things like editing profile pictures, or sharing parts of a photo online. It has been designed with the iOS Photos app editor in mind, and as such, behaves in a way that should already feel familiar to users of iOS.
For Swift developers, CropViewController is a Swift wrapper that completely encapsulates TOCropViewController and provides a much more native, Swiftier interface.
- Crop images by dragging the edges of a grid overlay.
- Optionally, crop circular copies of images.
- Rotate images in 90-degree segments.
- Clamp the crop box to a specific aspect ratio.
- A reset button to completely undo all changes.
- iOS 7/8 translucency to make it easier to view the cropped region.
- The choice of having the controller return the cropped image to a delegate, or immediately pass it to a UIActivityViewController.
- A custom animation and layout when the device is rotated to landscape mode.
- Custom ‘opening’ and ‘dismissal’ animations.
