Use of MBProgressHUD Globally + make it singleton

Question

In my Project, each of the user interaction events make a network call (Which is TCP, not HTTP). I need Activity Indicator to be global to show from a rando

Answer 1

This answer is what I've been using for 5-6 Apps now because it works perfectly inside blocks too. However I found a problem with it. I can make it shown, but can't make it disappear if a UIAlertView is also present. If you look at the implementation you can see why. Simply change it to this:

static UIWindow *window;

+ (MBProgressHUD *)showGlobalProgressHUDWithTitle:(NSString *)title {

    window = [[[UIApplication sharedApplication] windows] lastObject];
    MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:window animated:YES];
    hud.labelText = title;

    return hud;
}

+ (void)dismissGlobalHUD {

    [MBProgressHUD hideHUDForView:window animated:YES];
}

This will make sure you're removing the HUD from the same windows as it was shown on.
