I've used it as below..Hope it helps you..

in appDelegate.m

-(void)showIndicator:(NSString *)withTitleString currentView:(UIView *)currentView
{ 
if (!isIndicatorStarted) {

    // The hud will dispable all input on the view
    self.progressHUD = [[[MBProgressHUD alloc] initWithView:currentView] autorelease]; 
    // Add HUD to screen 
    [currentView addSubview:self.progressHUD]; 
    self.progressHUD.labelText = withTitleString;
    [window setUserInteractionEnabled:FALSE];
    [self.progressHUD show:YES];

    isIndicatorStarted = TRUE;
}   
 } 

-(void)hideIndicator 
{ 

    [self.progressHUD show:NO]; 
    [self.progressHUD removeFromSuperview]; 
    self.progressHUD = nil;
    [window setUserInteractionEnabled:TRUE];
    isIndicatorStarted = FALSE;
}

From Random Views:-

[appDel showIndicator:@"Loading.." currentView:presentView.view];
