iphone - 从 UIImagePickerController 相机 View 推送一个 viewController

Question

我正在开发一款消息传递应用程序(类似于 WhatsApp)，用户可以相互发送文本和图像消息。

当用户想要发送图片时，他可以从相机胶卷中选择一张，也可以用相机拍摄一张。

这就是我为这两种情况呈现 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/拍摄照片后，我将推送一个全屏显示图像的 SendImageViewController 并有一个实际发送图像的按钮。

这就是我插入它的方式:

- (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];
}  

当我从相机胶卷中推送 SendImageViewController 时，一切正常。问题是当从相机拍摄图像时，我无法推送我的 SendImageViewController，因为相机没有导航栏(我试图推送它，但我的 SendImageViewController View 呈现不佳)

我该如何处理？

* 我不想关闭选取器然后推送 SendImageViewController，我希望将 SendImageViewController 推送到顶部相机/相机胶卷 View ，所以当我点击后退按钮时，我将返回到相机/相机胶卷 View 。

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];
