ios - UIImage 和 prepareforSegue 无法传递图像

这是我的代码:

@property (weak, nonatomic) IBOutlet UIImageView *chosedImage;

    - (IBAction)cropImageTapid)sender {

        [self dismissViewControllerAnimated:YES completion:^{
             UIImage * pickedImage = self->_chosedImage;
            //[UIImage imageNamed"helloWorld.jpg"];

            [self performSegueWithIdentifier"gotomainimage" sender:pickedImage];

        }];
    }

我的表演继续如下:

 - (void)prepareForSegueUIStoryboardSegue *)segue senderid)sender
    {


        PostVC *vc = (PostVC*)segue.destinationViewController;
        UIImage *img = (UIImage*)sender;

        if (img.images == nil) {
            NSLog(@"null img");
             vc.Sourcemage = img;
        }
        else {

             NSLog(@"not null img");
             vc.Sourcemage = img;
        }

    }

我只得到空图像。我的图像没有出现。我在这里做什么问题？

请帮帮我

更新:

我更新后的代码，工作方式类似 - 给我控制台消息:

它的空数据a - post vc 它不是空图像 - prepareForSegue 方法

无法找出为什么会发生。

     - (IBAction)cropImageTapid)sender {


        UIImageView * pickedImage = _chosedImage;
        [self dismissViewControllerAnimated:YES completion:^{
            [self performSegueWithIdentifier"gotomainimage" sender:pickedImage.image];
        }];
    }

    - (void)prepareForSegueUIStoryboardSegue *)segue senderid)sender
    {

        PostVC *vc = (PostVC*)segue.destinationViewController;
        UIImage *img = (UIImage*)sender;

        if (img != nil) {
             NSLog(@"its not an null image");
            vc.Sourcemage = img;

        } else {
             NSLog(@"its an null image");
        }
    }

in my postvc :

    @property(nonatomic) UIImage *Sourcemage;
    - (void)viewWillAppearBOOL)animated {
        [super viewWillAppear:animated];



        if (self.Sourcemage != nil){
            NSLog(@"not null dataa");

            _PostImageView.image = _Sourcemage;

        } else {
    NSLog(@"not null dataa");
           _PostImageView.image = [UIImage imageNamed"Travel.png"];
        }


    }

Best Answer-推荐答案

你的目标 View Controller (PostVC)中的变量 Sourcemage 是 UIImage 吗？

请检查该属性是否为UIImage。
