ios - 通过video-graph.facebook iOS将视频上传到Facebook

Question

我正在尝试上传视频。我已将视频文件保存为MP4文件，如下所示:

NSString *fileName = [NSString stringWithFormat:@"chatVideo-%d.mp4",arc4random()%1000];
NSString *myPathDocs = [documentsDirectory stringByAppendingPathComponent:fileName];
NSURL *videoURL = [NSURL fileURLWithPath:myPathDocs];
AVAssetExportSession *exportSession = [AVAssetExportSession exportSessionWithAsset:asset2 presetName:AVAssetExportPresetHighestQuality];
exportSession.outputURL = videoURL;
exportSession.outputFileType = AVFileTypeMPEG4;
NSData *videodata =[NSData dataWithContentsOfURL:videoURL];

我调用了图谱API以上传到Facebook:

[parameters setValue:videoData forKey:@"source"];

    [parameters setValue:thumbData forKey:@"thumb"];

    [[[FBSDKGraphRequest alloc] initWithGraphPath:@"me/videos"
                                       parameters:parameters
                                       HTTPMethod:@"POST"]
     startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
         if ([error.userInfo[FBSDKGraphRequestErrorGraphErrorCode] isEqual:@200]) {
             NSLog(@"permission error");
         }
     }];

但我收到此错误:

抱歉，您选择的视频文件格式不支持。

Answer 1

是的，经过很长一段时间，我才找到答案:

[parameters setValue:videoData forKey:@"source"];

肯定是:

[parameters setValue:videoData forKey:@"video.mp4"];

我讨厌Facebook文档==!。
