Question

I am doing a modal view controller (changeviewcontroller) that will be appeared just 5 seconds , so how to do that ? what are the important codes i need to write?

Answer 1

Try this:
create a method in you modalview controller class to dismiss modal view controllr.

-(void)dismissModal{
   [self dissmissModalViewController];
}

Call this method with a delay of 5 seconds, from your viewdidLoad method.

-(void)viewDidLoad{
  [self performSelector @selector(dismissModal) afterDelay:5.0 ];

}

check the syntax, i am not using xcode .
