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^_^!
