Question

我正在使用库GKClass，它基本上是一个自定义的imagePickerController类。我无法传递数据 - 图像到下一个控件视图，而它正在使用简单的imagePickerController它现在不能正常工作，ViewController无法获取数据。

-(void)imagePicker:(GKImagePicker *)imagePicker pickedImage:(UIImage *)image
{
    VCImageEditingViewController *ieVC = [[VCImageEditingViewController alloc]init];
    ieVC.selectedIMG = image;
    [self.imagePicker.imagePickerController dismissViewControllerAnimated:NO completion:nil];
    [self performSegueWithIdentifier:@"imgrdy" sender:self];
}

和VCImageEditingViewController.m：

- (void)viewDidLoad
{
    [super viewDidLoad];
    if (self.selectedIMG == nil) {
        NSLog(@"no img set");
    }
    self.imageDisplayed.image = self.selectedIMG;
}

我也在viewDidAppear中尝试了它，但仍然没有，“选择器”在iv尝试后正在运行：

-(void)imagePicker:(GKImagePicker *)imagePicker pickedImage:(UIImage *)image
{
    [self.imagePicker.imagePickerController dismissViewControllerAnimated:NO completion:nil];
    self.lastImageView.image = image;
}

它显示当前视图控制器中的图像。

我的猜测是在修改图像之前显示目标viewController。

想要一些帮助。谢谢。

试试这个

 -(void)imagePicker:(GKImagePicker *)imagePicker pickedImage:(UIImage *)image
 {

 [self.imagePicker.imagePickerController dismissViewControllerAnimated:NO completion:nil];

  //pass image with peroformsegue
  [self performSegueWithIdentifier:@"imgrdy" sender: image];
 }

 // In prepare segue method assign image to destination view controller

 - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
 {
 if ([[segue identifier] isEqualToString:@"imgrdy"])
 {
       VCImageEditingViewController *ieVC=segue.destinationViewController;
        ieVC.selectedIMG =(UIImage *) sender;
 } 
 }

不会将图像传递到目标ViewController
