         #import <UIKit/UIKit.h>
        
         #import "MBProgressHUD.h"
        
         @interfaceHudDemoViewController : UIViewController <MBProgressHUDDelegate> {
        
             MBProgressHUD *HUD;
        
         }
        
         - (IBAction) showWithLabel:(id)sender;
        
         - (void) myTask;
        
         @end

@implementation HudDemoViewController

- (IBAction) showWithLabel:(id)sender {

	// Should be initialized with the windows frame so the HUD disables all user input by covering the entire screen
	HUD = [[MBProgressHUD alloc] initWithWindow:[UIApplication sharedApplication].keyWindow];

	// Add HUD to screen
	[self.view.window addSubview:HUD];
	[HUD release];

// Regisete for HUD callbacks so we can remove it from the window at the right time HUD.delegate = self;HUD.labelText = @"Loading";// Show the HUD while the provided method executes in a new thread[HUD showWhileExecuting:@selector(myTask) onTarget:self withObject:nil animated:YES];}- (void) myTask { // Do something usefull in here instead of sleeping ...sleep(3);}- (void)hudWasHidden:(MBProgressHUD *)HUD {// Remove HUD from screen when the HUD was hidded[HUD removeFromSuperview];}@end
