Question

这是一个iPhone应用程序，我有一个助手视图，它总是在窗口顶部（可以扩展和最小化）。视图内部有几个按钮，允许我在捕获图像，捕获视频和录制音频之间切换。在app delegate中，它看起来像：

[self.window addSubview:assistantFloatingViewController.view];
[self.window makeKeyAndVisible];
self.window.frame = [UIScreen mainScreen].bounds;

然后在助理视图中单击捕获图像按钮时添加UIImagePickerController：

- (void)presentImagePicker{
    UIImagePickerController *imagePickerController =    [[UIImagePickerController alloc] init];
    imagePickerController.delegate = self;
    imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
    imagePickerController.mediaTypes = @[(__bridge NSString *) kUTTypeImage];

    [self moveFromViewController:self.currentContentViewController ToViewController:imagePickerController];
    self.currentContentViewController = imagePickerController;
}

- (void)moveFromViewController:(UIViewController *)fromVC ToViewController:(UIViewController *)toVC {
   [fromVC willMoveToParentViewController:nil];

   [self addChildViewController:toVC];

   [fromVC.view removeFromSuperview];
   [fromVC removeFromParentViewController];

   [self.view addSubview:toVC.view];

   [toVC.view alignToView:self.containerView];

   [toVC didMoveToParentViewController:self];

   self.currentContentViewController = toVC;
}

问题出在我拍摄图像后，无法点按“重拍”和“用户照片”按钮（无响应）。

我在这里做错了什么？任何帮助将不胜感激！

Answer 1

替换代码的最后两行

[self moveFromViewController:self.currentContentViewController ToViewController:imagePickerController];
self.currentContentViewController = imagePickerController;

有了这个，

[self presentViewController:imgPicker animated:YES completion:^{

     // Your code
}];

iOS嵌入UIImagePickerController'使用照片按钮拍照后无效
