Do you use an UIAlertView as your popup?

If yes, your view controller has to be conform to the UIAlertViewDelegate protocol and you can implement the alertView:clickedButtonAtIndex: method in order to react to the button you clicked in the popup. Then you can push your view to the other.

in your View1... before you change your view from view1 to view2 put this line

[self performSelector:@selector(Method1) withObject:nil afterDelay:60]; 

it will call this method after 60 second in view2 keep one boolean variable... BoolAlert and set it in Method1 function write something like

-(void) Method1
{
View2viewController *view2 = [[ View2viewController alloc] initWithNibName:@"View2viewController" bundle:nil];
view2.BoolAlert = TRUE;
[self.navigationController pushViewController:view2 animated:YES];
        [view2 release];


}

in view2's viewDidLoad method write

- (void)viewDidLoad {
    [super viewDidLoad];
if(BoolAlert)
{
//show alert here 
}
}
