Question

我创建了一个记录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将显示，直到我的数据存储在服务器上。

我正在使用MKNetworkKit fot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);
    }
}

修改

现在已经完成了

我刚刚添加了此代码

[HUD removeFromSuperview];

目前

[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。

您需要在将数据上传到服务器后将其删除。

因此，您需要在完成块和错误块中编写删除代码。

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];        
}];
