如何在应用程序

当我登录并使用申请时，我必须找到恒定的带宽，直到我没有退出...

我试过这段代码，但它只给出了一个时间速度，我想要对带宽进行恒速跟踪..

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];

operation.downloadSpeedMeasure.active = YES;
[operation setUploadProgressBlock:^(NSUInteger bytesRead, long long totalBytesRead, long long totalBytesExpectedToRead)
 {

 }];
// to avoid a retain cycle one has to pass a weak reference to operation into the progress block.
[operation setDownloadProgressBlock:^(NSUInteger bytesRead, long long totalBytesRead, long long totalBytesExpectedToRead) {
     float progress = ((float)totalBytesRead) / totalBytesExpectedToRead;
    NSLog(@"%f",progress);
    double speedInBytesPerSecond = operation.downloadSpeedMeasure.speed;
    NSString *humanReadableSpeed = operation.downloadSpeedMeasure.humanReadableSpeed;
    double humanReadableSpeed1 = operation.downloadSpeedMeasure.speed;


   // NSTimeInterval remainingTimeInSeconds = [operation.downloadSpeedMeasure remainingTimeOfTotalSize:totalBytesExpectedToRead numberOfCompletedBytes:totalBytesRead];
   // NSString *humanReadableRemaingTime = [operation.downloadSpeedMeasure humanReadableRemainingTimeOfTotalSize:totalBytesExpectedToRead numberOfCompletedBytes:totalBytesRead];
    NSLog(@"humanReadableSpeed : %@",humanReadableSpeed);
    NSLog(@"humanReadableSpeed : %f",humanReadableSpeed1);

    //NSLog(@"speedInBytesPerSecond : %f",speedInBytesPerSecond);

}];
[operation start];

任何人都可以帮我找到如何使用任何第三方库，功能，演示获得恒定带宽????
