從UIImagePickerController攝像頭視圖中推送viewController

Question

我正在開發一個消息傳遞應用程序（類似於WhatsApp），用戶可以相互發送文本和圖像消息。

當用戶想要發送圖像時，他可以從相機膠卷中選擇一個，或者他可以用相機拍攝一個。

這就是我為兩種情況呈現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];
}

在用戶選擇/拍照后，我正在推送一個SendImageViewController ，它以全屏顯示圖像，並有一個實際發送圖像的按鈕。

這是我推動它的方式：

- (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];
}  

當我從相機膠卷推送SendImageViewController ，一切都很好。 問題是，當從相機拍攝圖像時，我無法推送我的SendImageViewController ，因為相機沒有導航欄（我試圖推動它但我的SendImageViewController視圖沒有很好地呈現）

我怎么處理這個？

*我不想解雇拾取器，然后推送SendImageViewController ，我希望SendImageViewController將被推到相機/相機膠卷的頂部，所以當我點擊后退按鈕時我會回到相機/相機膠卷視圖。

嘗試顯示導航欄，如下所示：

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

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