iOS FacebookSDK图像共享

Question

我正在使用以下代码将图像从iOS上传到Facebook。

NSMutableDictionary* params = [[NSMutableDictionary alloc] init]; 
[params setObject:@"MY TEST MSG..." forKey:@"message"]; 
[params setObject:UIImagePNGRepresentation(self.editImageView.image) forKey:@"picture"]; 


[[FBSDKGraphRequest alloc] initWithGraphPath:@"me/photos" parameters:params HTTPMethod:@"POST"] startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) { 
     if (!error) { 
      NSLog(@"uploaded"); 
     } else { 
      NSLog(@"Graph API Error: %@", [error description]); 
     } 
}]; 

我的应用程序被卡住了几分钟，并显示错误消息。 任何人都可以帮我吗？

NSMutableDictionary *variables = [NSMutableDictionary dictionaryWithCapacity:3]; 
UIImage *picture = FilterImage; 
FbGraphFile *graph_file = [[FbGraphFile alloc] initWithImage:picture]; 
[variables setObject:graph_file forKey:@"file"]; 
[variables setObject:[NSString stringWithFormat:@"Hello testin"] forKey:@"message"]; 
[fbGraph doGraphPost:@"me/photos" withPostVars:variables]; 
NSLog(@"Now log into Facebook and look at your profile & photo albums...");
