DZImageEditing

DZImageEditing is lightweight replacement for UIImagePickerController editing mode (support overlay, custom crop etc.)

Original UIImagePickerController editing mode have a lot of limitations:

• you can't add custom min/max zoomScale
• you can't add overlay for better positioning
• you can't give user opportunity to move image borders to the center of the screen
• you need to do all cropping work by yourself

With DZImageEditingController you can:

• setup minimum, maximum and default zoomScale value
• add custom overlay view
• select crop rect, so you'll get only area that you need
• move/scale your image in a way you need it without limitations

Using

Import 'DZImageEditingController.h'

#import "DZImageEditingController.h"

Init DZImageEditingController with 'alloc' 'init', and set parameters:

DZImageEditingController *editingViewController = [DZImageEditingController new];
//required
editingViewController.image = image;
//optional
editingViewController.overlayView = overlayImageView;
editingViewController.cropRect = CGRectMake(100.0f, 100.0f, 200.0f, 200.0f);
editingViewController.delegate = self;
editingViewController.minimumScale = 1.0f;
editingViewController.maximumScale = 2.0f;
editingViewController.defaultScale = 1.5f;

The only required parameter is 'image', all others are optional, and will be set automatically to default values.

DZImageEditingControllerDelegate got two optional methods:

For cropped image

- (void)imageEditingController:(DZImageEditingController *)editingController
     didFinishEditingWithImage:(UIImage *)editedImage;

If user canceled editing

- (void)imageEditingControllerDidCancel:(DZImageEditingController *)editingController;

Requirements

• iOS >= 7.0 (may work on iOS6, but will need light design changes)
• ARC
