Question

我做的就像从画廊中获取图像一样。将其显示在另一个视图中。我可以裁剪该图像，但我无法保存。请有人帮我怎么做。

 - (IBAction)cropClicked:(id)sender
   {
   [self.cropImgView crop];

   }
   - (void)JBCroppableImageView:(JBCroppableImageView *)controller didFinishCroppingImage:(UIImage *)croppedImage{
   imag = croppedImage;
   secondViewController *second=[[secondViewController alloc]initWithNibName:@"secondViewController" bundle:nil];
   second.cutimage.image=croppedImage;

   //   [[self navigationController] pushViewController:second animated:YES];

   //  [self presentViewController:second animated:YES completion:nil];

   [self dismissViewControllerAnimated:YES completion:nil];

   }

    To Save Crop image:
    First of all add property cutimage in FirstViewController.h file

        @interface FirstViewController
        @property (nonatomic , strong) UIImageView *cutimage;
        @end

        also initialize it in viewdidload of FirstViewcontoller 
        cutimage = [[UIImageView alloc] init]




    FirstViewController *objFirstViewController = [[FirstViewController alloc] init];
    objFirstViewController.objFirstVC = self;
    [self.navigationController pushViewController:objFirstViewController animated:NO] ;


     1. Create a property in .h file within 

        @interface SecondViewController  

        @property (nonatomic, strong) FirstViewController *objFirstViewController

        @end

     2. now within JBCroppableImageView method

        objFirstViewController.cutimage.image=croppedImage

    now within FirstViewcontroller "cutimage" object could be accessed to show CroppedImage.

如果您需要将图像保存到用户的相册，可以使用UIKit功能

void UIImageWriteToSavedPhotosAlbum ( UIImage *image, id completionTarget, SEL completionSelector, void *contextInfo );
