执行此操作时,它直接显示secondviewcontroller,我想要的是viewcontroller首先显示,40或50秒后显示secondviewcontroller,等等。延迟显示子视图
- (void)displayviewsAction:(id)sender
{
PageOneViewController *viewController = [[PageOneViewController alloc] init];
viewController.view.frame = CGRectMake(0, 0, 320, 480);
SecondViewController *secondController = [[SecondViewController alloc] init];
secondController.view.frame = CGRectMake(0, 0, 320, 480);
[self.view addSubview:viewController.view];
[self.view addSubview:secondController.view];
[self.view bringSubviewToFront:viewController.view];
[self.view addSubview:toolbar];
[self.view sendSubviewToBack:viewController.view];
[self.view addSubview:toolbar];
}
任何人有任何想法,我可以做到这一点。
