这是一个古老的问题，但是最新的Facebook iOS SDK v3.9可以实现您想做的事情. (2013年10月27日)

This is an old question but what you're trying to do is possible with latest Facebook iOS SDK v3.9. (27 Oct 2013)

本质上，FBRequestConnection公开了一个urlRequest(NSMutableURLRequest)属性，您可以使用该属性向其他任何第三方联网框架甚至Apple提供的框架发送数据.

Essentially, FBRequestConnection exposes a property urlRequest (NSMutableURLRequest) that you can use to send out the data any other third party networking frameworks or even the ones Apple provided.

这是一个示例，说明如何使用AFNetworking 1.x获取进度回调.

Here's an example how I get progress callbacks using AFNetworking 1.x.

NSDictionary *parameters = @{ @"video.mov": videoData,
                              @"title": @"Upload Title",
                              @"description": @"Upload Description" };

创建FBRequest

FBRequest *request = [FBRequest requestWithGraphPath:@"me/videos" 
                                          parameters:parameters
                                          HTTPMethod:@"POST"];

生成FBRequestConnection(取消并提取URLRequest)

FBRequestConnection *requestConnection = [request startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
}];
[requestConnection cancel];

NSMutableURLRequest *urlRequest = requestConnection.urlRequest;

使用AFNetworking HTTPRequestOperation

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:urlRequest];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
  // Do your success callback.
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
  // Do your failure callback.
}];

设置进度回调

[operation setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) {
  NSLog(@"Sent %lld of %lld bytes", totalBytesWritten, totalBytesExpectedToWrite);
}];

开始操作

[[APIClient sharedInstance] enqueueHTTPRequestOperation:operation];
// APIClient is a singleton class for AFHTTPClient subclass
