Cannot hide MBProgressHUD in iOS

Question

I tried this code to show MBProgressHUD but when I click on another tab and back to this tab, MBProgressHUD cannot hide. I tried this for 2 functions:

For updatearray()

 MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES]; hud.mode = MBProgressHUDModeIndeterminate; hud.labelText = @"Loading.."; dispatch_queue_t dispatchQueue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0); dispatch_async(dispatchQueue, ^(void) { [self updatearray]; dispatch_sync(dispatch_get_main_queue(), ^{ [hud hide:YES]; }); });

for getVideolist()

 MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES]; hud.mode = MBProgressHUDModeIndeterminate; hud.labelText = @"Loading.."; dispatch_queue_t dispatchQueue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0); dispatch_async(dispatchQueue, ^(void) { [self getVideolist]; dispatch_sync(dispatch_get_main_queue(), ^{ [hud hide:YES]; }); });

In first time, it runs ok. But after click on another tab and back, it cannot hide.

@ShivanRaptor: Yes, it finish loading. I've been updated my question. Pls check out. thanks — Joson Daniel

Try making your MBProgressHUD a private property (strong, nonatomic). Then you can reference the same instance of your progress hud in other methods or threads and update or hide it.
