Question

I have view controller with UIImageView . In view did load i want to set image on image view for particular time interval.After that image view should be cleared and application should switch to next screen. I have tried following code which is not working:

 welcomeImage.image=[UIImage imageNamed:@"abc.png"];
sleep(5);
homeScreenController *controller=[[homeScreenController alloc]initWithNibName:@"homeScreenController" bundle:nil];
controller.modalTransitionStyle=UIModalTransitionStyleCrossDissolve;
[self presentModalViewController:controller animated:YES];

In this case it is sleeping before view did load and it is not going to the next screen also. So what is wrong with the code?

Answer 1

Use the below code/..

- (void)viewDidLoad 
{
    [super viewDidLoad];
    [self performSelector:@selector(goToNextView) withObject:nil afterDelay:5.0];
}



- (void)goToNextView
{
        homeScreenController *controller=[[homeScreenController alloc]initWithNibName:@"homeScreenController" bundle:nil];
        controller.modalTransitionStyle=UIModalTransitionStyleCrossDissolve;
        [self presentModalViewController:controller animated:YES];


}
