A HUD that mimics the native one used in iOS (when you press volume up or down on the iPhone for instance) and also provides some more features (some more animations + activity indicator support included.)
#import "LGViewHUD.h"
..
#in a UIViewController ....
LGViewHUD* hud = [LGViewHUD defaultHUD];
hud.image=[UIImage imageNamed:@"rounded-checkmark.png"];
hud.topText=@"LGViewHUD";
hud.bottomText=@"you did it !";
# show it in current view (it will disappear 2 sec later)
[hud showInView:self.view]
#with an activity indicator
hud.activityIndicatorOn=YES;
