@interface SuprisedViewController : UIViewController {

    IBOutlet UIButton *marsStoryButton;
    IBOutlet UIButton *marsStoryHome;

    @property (nonatomic, retain) IBOutlet UIButton *marsStoryHome;
    @property (nonatomic, retain) IBOutlet UIButton *marsStoryButton;
    -(void)marsStoryButtonPressed;

@implementation SuprisedViewController

    @synthesize bolloLogo, scaryAlien, exorcist, image1, image2, marsMan, marsStoryButton, marsStoryHome;



    -(void)marsStoryButtonPressed {

      marsMan.hidden = NO;
marsStoryHome.hidden = NO;

CFBundleRef mainBundle = CFBundleGetMainBundle();
CFURLRef soundFileURLRef;
soundFileURLRef = CFBundleCopyResourceURL(mainBundle, (CFStringRef) @"longManScream", CFSTR ("wav"), NULL);

soundFileURLRef = CFBundleCopyResourceURL(mainBundle, (CFStringRef) @"spressedScream", CFSTR ("wav"), NULL);

soundFileURLRef = CFBundleCopyResourceURL(mainBundle, (CFStringRef) @"torturedGirlScream", CFSTR ("wav"), NULL);


UInt32 soundID;
AudioServicesCreateSystemSoundID(soundFileURLRef, &soundID);
AudioServicesPlaySystemSound(soundID);

AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);
}
