ios - Apple 的控制器在 iOS7 中无法正确显示

Question

在我的 iOS 应用程序中，我提供了标准控制器 MFMessageComposeViewController 和 UIImagePickerController。

但他们都呈现出奇怪的导航栏。

我该如何解决这个问题？

用于呈现控制器的UPD代码

UIImagePicker控制器：

UIImagePickerController *cameraUI = [[UIImagePickerController alloc] init];
    cameraUI.sourceType = sourceType;
    cameraUI.allowsEditing = YES;
    cameraUI.delegate = self;
    [self presentViewController:cameraUI animated:YES completion:nil];

MFMessageComposeViewController：

MFMessageComposeViewController *messageViewController = [[MFMessageComposeViewController alloc] init];
    if([MFMessageComposeViewController canSendText]) {
        messageViewController.view.backgroundColor = [UIColor whiteColor];
        messageViewController.messageComposeDelegate = self;
        recipient= [NSStringMask maskString:recipient withPattern:@"\\+(\\d{1}) \\((\\d{3})\\) (\\d{3})-(\\d{2})-(\\d{2})"];
        messageViewController.recipients = @[recipient];
        messageViewController.body = body;
        [self presentViewController:messageViewController animated:YES completion:nil];
    }

In iOS 7, the status bar and the navigation is translucent by default. To make the view act 'normal' like in iOS 6. you need to add this to the controller you are presenting.

if ([self respondsToSelector:@selector(edgesForExtendedLayout)])
        self.edgesForExtendedLayout = UIRectEdgeNone;

看到这个问题。我使用了第二个答案，尽管我怀疑第一个答案也对我有用。
