RSKImageCropper

https://github.com/ruslanskorb/RSKImageCropper

An image cropper for iOS like in the Contacts app with support for landscape orientation.

一个iOS图片裁剪器,支持横竖屏切换.

Installation - 安装

CocoaPods is the recommended method of installing RSKImageCropper. Simply add the following line to your Podfile:

Podfile

pod 'RSKImageCropper'

Basic Usage - 基本用法

Import the class header.

包含头文件.

#import "RSKImageCropViewController.h"

Just create a view controller for image cropping and set the delegate.

创建一个图片的控制器,并在代理方法中执行裁剪操作.

- (IBAction)onButtonTouch:(UIButton *)sender
{
    UIImage *image = [UIImage imageNamed:@"image"];
    RSKImageCropViewController *imageCropVC = [[RSKImageCropViewController alloc] initWithImage:image];
    imageCropVC.delegate = self;
    [self.navigationController pushViewController:imageCropVC animated:YES];
}

Delegate - 代理

RSKImageCropViewControllerDelegate provides two delegate methods. To use them, implement the delegate in your view controller.

RSKImageCropViewControllerDelegate提供了两个代理方法.你需要在你的控制器中实现代理方法.

@interface ViewController () <RSKImageCropViewControllerDelegate>

Then implement the delegate functions.

然后,实现代理方法.

// Crop image has been canceled.
- (void)imageCropViewControllerDidCancelCrop:(RSKImageCropViewController *)controller
{
    [self.navigationController popViewControllerAnimated:YES];
}

// The original image has been cropped.
- (void)imageCropViewController:(RSKImageCropViewController *)controller didCropImage:(UIImage *)croppedImage
{
    self.imageView.image = croppedImage;
    [self.navigationController popViewControllerAnimated:YES];
}

Coming Soon - 将要实现的功能

• Add more cropping guides. 支持更多的裁剪类型
• If you would like to request a new feature, feel free to raise as an issue. 如果你有着奇葩的想法,你可以提出来哦,亲^_^!

Demo - 应用示例

Build and run the RSKImageCropperExample project in Xcode to see RSKImageCropper in action. Have fun. Fork and send pull requests. Figure out hooks for customization.

编译以及运行RSKImageCropperExample工程,并做交互操作即可.
