ios - UIImagePickerController 黑色不透明底栏

Question

我需要我的 View 在拍照时有一个黑色不透明的底部和顶部栏。我希望它看起来完全像这样:

这实际上是我在运行 iOS 7 的 iPhone 5 上运行我的代码。但是当我在 iPhone 4S(也是 iOS 7)上编译我的代码时，底部栏变得透明 - View 变成了从上到下的相机底部，就像现在的相机应用程序一样。甚至“拍照”按钮也变得透明，就像 SnapChat 一样。我讨厌这个。我需要更改什么设置才能使底部栏在我的 iPhone 4S 上变得不透明？我正在使用自动布局。

这是在我的 viewDidAppear 中:

if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
    {
        self.anImagePickerController = [UIImagePickerController new];
        self.anImagePickerController.delegate = self;
        self.anImagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
        self.anImagePickerController.showsCameraControls = YES;

        [self presentViewController:self.anImagePickerController animated:NO completion:Nil];
    }

下面的代码将完全按照您的要求执行。我自己发现了这一点，因为我想做和你完全一样的事情，并且觉得完全没有必要滚动你自己的相机 Controller 。

UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.allowsEditing = YES;
imagePicker.cameraFlashMode = UIImagePickerControllerCameraFlashModeAuto;
imagePicker.delegate = self;

 [self presentViewController:imagePicker animated:YES completion:^()
 {   
     for (UIView *subview in imagePicker.view.subviews)
     {
        if([NSStringFromClass([subview class]) isEqualToString:@"UINavigationTransitionView"])
        {
            UIView *theView = (UIView *)subview;

            for (UIView *subview in theView.subviews)
            {
               if([NSStringFromClass([subview class]) isEqualToString:@"UIViewControllerWrapperView"])
               {
                   UIView *theView = (UIView *)subview;

                    for (UIView *subview in theView.subviews)
                    {
                         if([NSStringFromClass([subview class]) isEqualToString:@"PLCameraView"])
                         {
                             UIView *theView = (UIView *)subview;

                             for (UIView *subview in theView.subviews)
                             {
                                 if([NSStringFromClass([subview class]) isEqualToString:@"CAMTopBar"])
                                 {
                                      subview.backgroundColor = [UIColor blackColor];
                                 }
                                 if([NSStringFromClass([subview class]) isEqualToString:@"CAMBottomBar"])
                                 {
                                      subview.backgroundColor = [UIColor blackColor];
                                 }
                                 if([NSStringFromClass([subview class]) isEqualToString:@"PLCropOverlay"])
                                 {
                                     UIView *theView = (UIView *)subview;

                                     for (UIView *subview in theView.subviews)
                                     {
                                         if([NSStringFromClass([subview class]) isEqualToString:@"PLCropOverlayBottomBar"])
                                         {
                                              UIView *theView = (UIView *)subview;

                                              for (UIView *subview in theView.subviews)
                                              {
                                                  if([NSStringFromClass([subview class]) isEqualToString:@"PLCropOverlayPreviewBottomBar"])
                                                  {
                                                      subview.backgroundColor = [UIColor blackColor];
                                                  }
                                              }
                                          }
                                      }
                                  }
                              }
                          }
                      }
                 }
             }
         }
     }
}];
