Answer 1

Try this one..

You change the code in Appdelegate.m didFinishLaunchingWithOptions method like this

self.viewController = [[ViewController alloc] initWithNibName:@"ViewController" bundle:nil];
UINavigationController *nav=[[UINavigationController alloc]initWithRootViewController:self.viewController];
self.window.rootViewController = nav;

And in your ViewDidLoad method like this..

welcomePage *temp = [[welcomePage alloc]initWithNibName:@"welcomePage" bundle:nil];       
[self.navigationController presentViewController:temp animated:YES completion:nil];

For dismissing viewcontroller you can write following code in welcomepage button action

-(IBAction)dismiss:(id)sender{
[self dismissViewControllerAnimated:YES completion:nil];
}
