FBTweakBind(sharedInstance, jpgQuality,

FBTweakBind(self, isHinet, @"System", @"Params", @"isHinet", YES);

NSOperationQueue *serviceQueue = [NSOperationQueue new];
FBTweakBind(serviceQueue, maxConcurrentOperationCount,
                    @"NSOperationQueue", @"Web Service Queue", @"Concurrent", 1);
