An image cropper for iOS like in the Contacts app with support for landscape orientation.
CocoaPods is the recommended method of installing RSKImageCropper. Simply add the following line to your Podfile:
pod 'RSKImageCropper'Import the class header.
#import "RSKImageCropViewController.h"Just create a view controller for image cropping and set the delegate.
- (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.
@interface ViewController () <RSKImageCropViewControllerDelegate>Then implement the delegate functions.
// 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.
