我已经创建了一个录制视频并将其存储在服务器上的应用程序，现在我想在我的应用程序中添加 HUD，这个 HUD 将一直显示，直到我的数据存储在服务器上。

我正在使用 MKNetworkKit 将数据发布到服务器。

我试过这个：

- (void) imagePickerController: (UIImagePickerController *) picker
 didFinishPickingMediaWithInfo: (NSDictionary *) info {

    NSString *mediaType = [info objectForKey: UIImagePickerControllerMediaType];

    //NSLog(@"medea type is: %@ ",mediaType);

    if ([mediaType isEqualToString:@"public.movie"]){
      //  NSLog(@"got a movie");
        NSURL *videoURL = [info objectForKey:UIImagePickerControllerMediaURL];
        webData = [NSData dataWithContentsOfURL:videoURL];

    }

    [self dismissModalViewControllerAnimated:NO];

    // Handle a movie capture
    if (CFStringCompare ((__bridge_retained CFStringRef) mediaType, kUTTypeMovie, 0)
        == kCFCompareEqualTo) {

        NSString *moviePath = [[info objectForKey:
                                UIImagePickerControllerMediaURL] path];
        if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum (moviePath)) {
            UISaveVideoAtPathToSavedPhotosAlbum (moviePath,self, @selector(video:didFinishSavingWithError:contextInfo:), nil);
        } 
    }

    self.flUploadEngine = [[fileUploadEngine alloc] initWithHostName:@"reneveledat.net" customHeaderFields:nil];

    NSMutableDictionary *postParams = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                       @"testApp", @"appID",
                                       nil];      
    self.flOperation = [self.flUploadEngine postDataToServer:postParams path:@"/dilipvideotest/savefile.php"];
    [self.flOperation addData:webData forKey:@"uploadfile" mimeType:@"video/mov" fileName:@"upload.mov"];

    [self.flOperation onCompletion:^(MKNetworkOperation *operation) {

        NSLog(@"response string is : %@", [operation responseString]);

        response = [operation responseString] ;
[HUD removeFromSuperview];
        /*   
         This is where you handle a successful 200 response
         */
    }     
                           onError:^(NSError *error) {
                               NSLog(@"error : %@", error);
                               UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error"
                                                                               message:[error localizedDescription]
                                                                              delegate:nil
                                                                     cancelButtonTitle:@"Dismiss"
                                                                     otherButtonTitles:nil];
                               [alert show];        
                           }];



    [self.flUploadEngine enqueueOperation:self.flOperation ];

    // for HUD

    HUD = [[MBProgressHUD alloc] initWithView:self.view];
    HUD.labelText = @"Doing funky stuff...";
    HUD.detailsLabelText = @"Just relax";
    HUD.mode = MBProgressHUDModeAnnularDeterminate;
    [self.view addSubview:HUD];

    [HUD showWhileExecuting:@selector(doSomeFunkyStuff) onTarget:self withObject:nil animated:YES];


   }

- (void)doSomeFunkyStuff {
    float progress = 0.0;

    while (progress < 1.0) {
        progress += 0.01;
        HUD.progress = progress;
        usleep(50000);
    }
}

编辑

现在完成了

我刚刚添加了这段代码

[HUD removeFromSuperview];

在

[self.flOperation onCompletion:^(MKNetworkOperation *operation) {

            NSLog(@"response string is : %@", [operation responseString]);

            response = [operation responseString] ;
    [HUD removeFromSuperview];
            /*   
             This is where you handle a successful 200 response
             */
        }

您正在视图中添加 MBProgressHUD。

数据上传到服务器后，您需要将其删除。

所以你需要在完成块和错误块内编写删除代码。

像：

[self.flOperation onCompletion:^(MKNetworkOperation *operation)
{
    [MBProgressHUD hideHUDForView:self.view animated:YES];
    NSLog(@"response string is : %@", [operation responseString]);
    response = [operation responseString] ;
}     
onError:^(NSError *error)
{
   [MBProgressHUD hideHUDForView:self.view animated:YES];
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:[error localizedDescription] delegate:nil cancelButtonTitle:@"Dismiss" otherButtonTitles:nil];
    [alert show];        
}];
