MBProgressHUD to Singleton

Question

I want to set method for showing and dismissing HUD in Singleton. I write this method in singleton:

- (void)showHUD
{
    activityHud = [[MBProgressHUD alloc] init];
    activityHud.delegate = self;
}

but nothing happened. For dismissing, I have no idea how to write... Any answer will be very helpful. Thanks!

Answer 1

Why not use static methods? I use this and put it in my util class.

static UIWindow *window;  
+ (MBProgressHUD *)showGlobalProgressHUDWithTitle:(NSString *)title {
window = [[[UIApplication sharedApplication] windows] lastObject];
MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:window animated:YES];
hud.labelText = title;

return hud;

}

and hide it with this :

+ (void)dismissGlobalHUD {

[MBProgressHUD hideHUDForView:window animated:YES]; 
}
