从 UIImagePickerController 相机视图推送一个 viewController

Question

我正在开发一种消息应用程序（类似于 WhatsApp），用户可以相互发送文本和图像消息。

当用户想要发送图像时，他可以从相机胶卷中选择一张，也可以用相机拍摄一张。

这就是我在这两种情况下呈现UIImagePickerController 的方式：

- (void)handleTakePhoto
{
    UIImagePickerController *ipc = [[UIImagePickerController alloc] init];

    ipc.delegate = self;
    ipc.sourceType = UIImagePickerControllerSourceTypeCamera;

    [self presentModalViewController:ipc animated:YES];
    [ipc release];
}

- (void)handleChooseFromLibrary
{
    UIImagePickerController *ipc = [[UIImagePickerController alloc] init];
    ipc.delegate = self;
    ipc.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;

    NSString *desired = (NSString *)kUTTypeImage;
    if ([[UIImagePickerController availableMediaTypesForSourceType:UIImagePickerControllerSourceTypePhotoLibrary] containsObject:desired]) {
        ipc.mediaTypes = [NSArray arrayWithObject:desired];
    }

    [self presentModalViewController:ipc animated:YES];
    [ipc release];
}

在用户选择/拍照后，我正在推送一个SendImageViewController，它会全屏显示图像并有一个按钮来实际发送图像。

我是这样推的：

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];


    SendImageViewController *sivc = [[SendImageViewController alloc] initWithImage:image
                                                                          delegate:self];
    [picker pushViewController:sivc animated:YES];
    [sivc release];
}  

当我从相机胶卷中按下SendImageViewController 时，一切正常。 问题是从相机拍摄图像时我无法推送我的SendImageViewController，因为相机没有导航栏（我尝试推送它，但我的SendImageViewController 视图呈现不佳）

我该如何处理？

* 我不想关闭选择器然后推送SendImageViewController，我希望SendImageViewController 会被推送到相机/相机胶卷的顶部，所以当我点击返回按钮，我将返回相机/相机胶卷视图。

尝试像这样显示导航栏：

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackTranslucent animated:YES];
[[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationSlide];

[picker setNavigationBarHidden:NO animated:YES];
[picker pushViewController:vc animated:YES];
