video - 保存 UIImagePicker 视频

Question

我搜索了又搜索，但找不到基本的 UIImagepicker 视频保存代码。 我已设置好所有内容，只是一片空白。

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

我知道这与字典有关，但在那之后我迷路了，有什么帮助吗？

尝试使用此代码将视频保存到相册。

    - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
    {
        [self dismissModalViewControllerAnimated:YES];

        //get the videoURL 
        NSString *tempFilePath = [[info objectForKey:UIImagePickerControllerMediaURL] path];

        if ( UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(tempFilePath))
        {
                // Copy it to the camera roll.
                UISaveVideoAtPathToSavedPhotosAlbum(tempFilePath, self, @selector(video:didFinishSavingWithError:contextInfo:), tempFilePath);
            } 
    }

    - (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
        [self dismissModalViewControllerAnimated:YES];
    }

    - (void) video: (NSString *) videoPath
    didFinishSavingWithError: (NSError *) error
       contextInfo: (void *) contextInfo {
        NSLog(@"Finished saving video with error: %@", error);
    }
