ios - 苹果的 Controller 无法在iOS7中正确显示

在我的iOS应用中，我展示了标准控制器MFMessageComposeViewController和UIImagePickerController。

但是它们都带有奇怪的导航栏。







我该如何解决这个问题？

用于呈现控制器的UPD代码

UIImagePickerController：

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];
    }

最佳答案

请参见this question。我使用了第二个答案，尽管我怀疑第一个答案也会对我有用。
