VFImageCropViewController

• Interactive resizable crop frame
• Fixed or not fixed aspect rario
• Standard aspect ratios: choose from the list

VFImageCropViewController *cropVC = [[VFImageCropViewController alloc]
                                      initWithImage:image aspectRatio:aspectRatio];
    
cropVC.cropImageActionHandler = ^(VFImageCropViewController *sender, UIImage *image, CGRect rect) {
    myImageView.image = image;
    [sender dismissViewControllerAnimated:YES completion:nil];
};
    
cropVC.cancelActionHandler = ^(VFImageCropViewController *sender) {
    [sender dismissViewControllerAnimated:YES completion:nil];
};
    
UINavigationController *navigationVC = [VFImageCropConfiguration imageCropViewControllerModalConfiguration:cropVC];
[myViewController presentViewController:navigationVC animated:YES completion:nil];

Note VFImageCropConfiguration in the example above. VFImageCropViewController is not aware about its presentation context (whether it is presented with UINavigationController, etc). Presentation details must be configured explicitly by its client.
