iPhone:从相机捕获视频后打开新的 View Controller

Question

我想在按下停止视频捕获按钮后打开新的 View Controller 。 我正在使用这段代码，但我无法做到这一点。

-(void)shootvideo
    {


    UIImagePickerController *imagePicker =
    [[UIImagePickerController alloc] init];
    imagePicker.delegate = self;


        imagePicker.sourceType =  UIImagePickerControllerSourceTypeCamera;



        imagePicker.mediaTypes = [[NSArray alloc] initWithObjects:(NSString *)kUTTypeMovie, nil];

    [self presentModalViewController:imagePicker animated:YES];


    }




    -(void) imagePickerController: (UIImagePickerController *) picker
    didFinishPickingMediaWithInfo: (NSDictionary *) info 
    {

    NSString *mediaType = [info objectForKey: UIImagePickerControllerMediaType];

         if (CFStringCompare ((__bridge CFStringRef) mediaType, kUTTypeMovie, 0)
         == kCFCompareEqualTo) 
         {

         NSString *moviePath = [[info objectForKey:UIImagePickerControllerMediaURL] path];

           NSURL *videoUrl=(NSURL*)[info objectForKey:UIImagePickerControllerMediaURL];


         if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum (moviePath)) {
         UISaveVideoAtPathToSavedPhotosAlbum (moviePath, nil, nil, nil);
         }
         }


         [self dismissModalViewControllerAnimated:YES];

         // nextviewcontroller *test=[[nextviewcontroller alloc]init];

     //[self.navigationController pushViewController:test animated:YES];




         }

    }

按下停止捕获视频按钮后，我想导航到另一个 View 。

您已经通过 presentModalViewcontroller 呈现了图像选择器，因此您无法在图像选择器上调用 [self.navigationController PushViewController:testanimated:YES]; 。您有两种选择，一种是简单的

1) 无需在图像选择器上调用 [selfmissModalViewControllerAnimated:YES];，只需调用

   nextviewcontroller *test=[[nextviewcontroller alloc]init];
   [self presentModalViewController:nextviewcontroller animated:YES];

2) 使用委托(delegate)调用新的 View Controller 。
