在 iOS 上使用 FB SDK 将视频上传到 Facebook 会消除方向。我该如何修复它？

我可以使用 facebook iOS SDK 上传到 facebook。然而，在应用程序（我们自己的应用程序）中以纵向拍摄的视频最终会在 Facebook 上以横向方式拍摄。

ALAssetRepresentation *rep = [asset defaultRepresentation];      
Byte *buffer = (Byte*)malloc(rep.size);      
NSUInteger buffered = [rep getBytes:buffer fromOffset:0.0 length:rep.size error:nil]; 
NSData *data = [NSData dataWithBytesNoCopy:buffer length:buffered freeWhenDone:YES];

以上是将视频文件转换为 NSData 文件的代码，该文件包含在 FB 上传请求中。我想这就是我失去方向的地方，但我找不到解决方案。有什么帮助吗？

谢谢，

克里斯

原文

I can upload to facebook just fine using the facebook iOS SDK. However, a video shot in the app (our own app) in portrait orientation ends up in landscape on facebook.

ALAssetRepresentation *rep = [asset defaultRepresentation];      
Byte *buffer = (Byte*)malloc(rep.size);      
NSUInteger buffered = [rep getBytes:buffer fromOffset:0.0 length:rep.size error:nil]; 
NSData *data = [NSData dataWithBytesNoCopy:buffer length:buffered freeWhenDone:YES];

Above is the code that converts the video file to a NSData file that is included in the FB upload request. I imagine that's where i'm losing the orientation, but i can't find a solution. Any help out there?

Thanks,

Chris
