This class provides the feature to draw a rectangle over an image by dragging a finger over it, move it, and extract the covered region into a UIImage.
A simple image cropper.
MMSCropImageView requires iOS 9.0 or later.
In your storyboard select the custom class MMSCropImageView for the Image View widget.
Import the class header.
#import <MMSCropImageView.h>Add an event handler to initiate the crop action and call the crop method on the image view.
- (IBAction)crop:(UIButton *)sender {
UIImage* croppedImage; // = self.imageView.image;
croppedImage = [self.imageView crop];
self.croppedView.image = croppedImage;
}Build and run the CropDemo project in Xcode to see MMSCropImageView in action.
