ios - 弹出 UIImagePickerController 后 UINavigationBar 消失

Question

我有一个嵌入在 UITabBarController 中的 UIViewController。在我的 PhotoViewController 上，用户可以选择添加照片并调用 UIImagePickerController。用户选择照片并弹出 View 后，导航栏消失。

显示导航栏。

这是 UIImagePickerController View ，看起来好像取消按钮在 NavigationBar 下。 (在这张图片中很难看到。)

UIImagePickerController 弹出并重新加载 View 后，NavigationBar 消失了。

下面是我如何调用 UIImagePickerController。我继承自 UIImagePickerControllerDelegate

 UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
    imagePickerController.modalPresentationStyle = UIModalPresentationCurrentContext;
    imagePickerController.sourceType = sourceType;
    imagePickerController.delegate = self;

    if (sourceType == UIImagePickerControllerSourceTypeCamera) {
        imagePickerController.showsCameraControls = YES;
    }

    self.imagePickerController = imagePickerController;
    [self presentViewController:self.imagePickerController animated:YES completion:nil];

尽管代表说它不兼容。

如何纠正问题？

Answer 1

我加了

imagePickerController.modalPresentationStyle = UIModalPresentationFullScreen;
imagePickerController.modalTransitionStyle   = UIModalTransitionStyleCoverVertical;

这似乎将 imagePickerController 置于当前 View 之上。
