How to load view controller without button in storyboard?

问题

I want to load view controller without button. I set the identifier to 10 and tried to use

if(...){ 
    //load ViewController2
    [[self storyboard] instantiateViewControllerWithIdentifier:@"10"];
}

but nothing happens.

with this function its doesnt work too

 UIViewController *vc = [[self storyboard] instantiateViewControllerWithIdentifier:@"10"];

[self.navigationController pushViewController:vc];

here is my progect http://www.sendspace.com/file/kfjhd5

whats a problem?

回答1:

Calling instantiateViewControllerWithIdentifier: will instantiate a view controller, as it says. Nothing more. If you want to actually show it you have to use a variable and push it to your view controller stack.

UIViewController *vc = [[self storyboard] instantiateViewControllerWithIdentifier:@"10"];
[self.navigationController pushViewController:vc];

Of course you have to be using a UINavigationController to do this.
