ios - 有什么方法可以在 iOS 7 中为 UIImagePickerController、源类型 UIImagePickerControllerSourceTypeCamera 显示导航栏？

Question

在 iOS 6 中，我使用以下代码推送源类型为 UIImagePickerControllerSourceTypeCamera 的 UIImagePickerController，并显示其导航栏。我想显示导航栏，因为在拍摄图像后，我正在推送另一个允许用户在数据库中设置一些属性的 VC。

if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
    cameraController = [[UIImagePickerController alloc] init];

    cameraController.delegate = self;
    cameraController.sourceType = UIImagePickerControllerSourceTypeCamera;

    [self presentViewController:cameraController animated:YES completion:NULL];

    [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleDefault animated:YES];
    [[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationSlide];
    cameraController.topViewController.title = @"Add";
    cameraController.navigationBar.translucent = NO;
    cameraController.navigationBar.barStyle = UIBarStyleDefault;

    [cameraController setNavigationBarHidden:NO animated:NO];
}

在 iOS 7 中，这段代码不再显示导航栏。有谁知道是否有办法为源类型为 UIImagePickerControllerSourceTypeCamera 的 UIImagePickerController 取回导航栏？

你猜怎么着？当 imagePicker 呈现时，它会自动设置为隐藏....
您需要做的就是在下一个运行循环中设置隐藏:否。喜欢:

[self presentModalViewController:imagePicker animated:YES];
[self performSelector:@selector(showNavigationBar:) withObject:imagePicker afterDelay:0];

- (void)showNavigationBar:(UIImagePickerController*)imagePicker {
    [imagePicker setNavigationBarHidden:NO];
}
