ios - 图像未显示在另一个屏幕上

Question

在我选择照片库中的图像后，它不会显示在另一个屏幕的 View 中。有任何想法吗？？这是prepareforsegue。不知道是不是这部分有问题还是可能。

   - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
     {
    if ([segue.identifier isEqualToString:@"InfoSegue"]) {
    UITabBarController* tabBar = segue.destinationViewController;

    InstructionsViewController* instructions = [tabBar.viewControllers[0]      
    viewControllers][0];
    instructions.delegate = self;

    SettingsViewController* settings = [tabBar.viewControllers[1] viewControllers][0];
    settings.delegate = self;

    MoreViewController* more = [tabBar.viewControllers[2] viewControllers][0];
    more.delegate = self;
    UINavigationController* navSubscription = [[UIStoryboard storyboardWithName:STORYBOARD_FILE_NAME bundle:nil] instantiateViewControllerWithIdentifier:@"SubscriptionStoryboardID"];
    SubscriptionViewController* subscription = navSubscription.viewControllers[0];
    subscription.delegate = self;

    NSMutableArray* viewControllers = [tabBar.viewControllers mutableCopy];
    [viewControllers insertObject:navSubscription atIndex:viewControllers.count - 1];
    tabBar.viewControllers = viewControllers;

} else if ([segue.identifier isEqualToString:@"EditorScreenSegue"]) {
    [DesignController startDesign:_selectedDesign];

    EditorViewController* editor = segue.destinationViewController;
    editor.delegate = self;
}
else if ([segue.identifier isEqualToString:@"MyDesignsSegue"]) {
    MyDesignsViewController* designs = segue.destinationViewController;
    designs.delegate = self;
}
}

Answer 1

 else if ([segue.identifier isEqualToString:@"EditorScreenSegue"]) {
    [DesignController startDesign:_selectedDesign];

    EditorViewController* editor = segue.destinationViewController;
    editor.delegate = self;

  // Use this code
  editor.selectedImage = currentImage;
  // selectedImage = its a UIImage property in EditorViewController.h
  // currentImage = its a UIImage reference for current view controller selected image object
}

在 else if block 中找到添加的行。您没有传递 UIImage 对象，那么它将如何显示。如代码所示，在下一个 View 中，您应该在代码中使用 selectedImage 引用。

希望这会给你一个提示，你错​​过了什么。
