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.
CocoaPods is the recommended method of installing RSKImageCropper. Simply add the following line to your Podfile:
pod 'RSKImageCropper'
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]; }
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]; }
- 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^_^!
