MBProgessHUD show on method execution

Question

I am writing app that will Sync with address book and keep itself updated to addressbook.

When i am calling the syncing method or when its first launch and the app is copying all addressbook contact to the app data file, i want to show MBProgressHUD to the user.

I don't understand this well, i want the MBProgressHUD to show up on the call of this method, and to hide when its done.

- (void)syncingAddressbookWithCoreDataFile

Can you guide me how to use it in the way that i want?

I am confused with all the dispatch and the queues stuff because i am quite novice in all these things.

UPDATED

How can i make the progress of the indicator fill in as the task gets executed, i know there is a progress property in HUD (i am using MBProgressHUDModeDeterminate), but when i increase its value while my method is executing it doesn't change.. do i need to call something like redisplay?

When you are calling the Sync method you should call [MBProgressHUD showHUDAddedTo:view animated:YES] and then when syncing is finished you should call [MBProgressHUD hideAllHUDsForView:keyWindow animated:animated]. Is that what you wanted to do? — Szu, Jul 22 '14 at 12:28

With this code, you have the simpliest way to do what you want. It's not blocking the UI.

MBProgressHUD *hud = [[MBProgressHUD alloc] initWithView: self.view];
[self.view addSubview: hud];
hud.labelText = @"Please wait...";

[hud showAnimated:YES whileExecutingBlock:^{
    [self syncingAddressbookWithCoreDataFile];
} completionBlock:^{
    // Put here code like reload table, refresh UI (...)
}];

But warning, as whileExecutingBlock using thread you have to make all UI change on main thread.

Works like a charm, thank you. If i want to display completed indicator just after completion, do i create another HUD? or that would be a normal view? What if i want to make loading indicator (circle filling) while syncing, is that too much advanced? – Moody Jul 22 '14 at 13:37

- (void)syncingAddressbookWithCoreDataFile { 

      [MBProgressHUD showHUDAddedTo:self.view animated:YES];

      //Your code goes here


      [MBProgressHUD hideHUDForView:self.view animated:YES];

}

Add this code where you want to show progress :

  [MBProgressHUD showHUDAddedTo:self.view animated:YES];

Now Add this code where you want to hide progress

    [MBProgressHUD hideHUDForView:self.view animated:YES];

Set your view where you want to display progress in : showHUDAddedTo && hideHUDForView

I called `[MBProgressHUD showHUDAddedTo:self.view animated:YES];` before just before i call my sync method and hide after it.. It doesn't work. – Moody Jul 22 '14 at 13:20
