Question

I have 2 ViewControllers and I create one UIImageView to show like Splash Screen on IPhone. I write it in TestAppDelegate.m :

====================

splashScreen = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];

splashScreen.image = [UIImage imageNamed:@"Default.png"];

[self.window addSubview:splashScreen];

 sleep(6);

[splashScreen removeFromSuperview];

====================

My question is,

if I touch on this imageview I will go to 2nd ViewController.

else after time sleep, automatically to 1st ViewController.

So, it’s possible to do that ?

Do this:

Add UIGestureRecognizerDelegate in appDelegate.h file.

@interface AppDelegate : UIResponder <UIApplicationDelegate,UIGestureRecognizerDelegate>

Now

splashScreen = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
splashScreen.userInteractionEnabled = YES;
splashScreen.image = [UIImage imageNamed:@"Default.png"];
UITapGestureRecognizer* tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap:)];
tapRecognizer.numberOfTapsRequired = 1;
tapRecognizer.numberOfTouchesRequired = 1;
tapRecognizer.delegate = self;
[splashScreen addGestureRecognizer:tapRecognizer];
[tapRecognizer release];

[self.window addSubview:splashScreen];

sleep(6);
[splashScreen removeFromSuperview];
//add ViewController1 here
ViewController1 *objViewController1 = [[ViewController1 alloc]initWithNibName:@"ViewController1" bundle:nil];
[self.window addSubview:objViewController1.view];

Now handler will be called when tapped on splash screen

- (void)handleTap:(UITapGestureRecognizer*)recognizer
{
   // Do Your thing. 
   if (recognizer.state == UIGestureRecognizerStateEnded)
   {
     [splashScreen removeFromSuperview]; //edited here
     ViewController2 *objViewController2 = [[ViewController2 alloc]initWithNibName:@"ViewController2" bundle:nil];
    [self.window addSubview:objViewController2.view];
   }
}
