UIAlertView button to display viewController

Question

I've been looking all over the internet for a solution to this problem, yet to find one that I can understand. So here it goes. I have my iOS application, on which on the first launch of the application, will display a UIAlertView. I want one of the buttons to send the user to a new viewController to view some essential information.

I have gotten my UIAlertView configured properly, here's the code for the actionSheet:

- (void)alertView:(UIAlertView *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
if (buttonIndex == 0)
{

//Code to open a new viewController???


}

if (buttonIndex == 1)
{

//User can exit the application if they do not wish to continue

exit(0);    }

}
}

I have a viewController created named webViewViewController, that's what I want users to reach when they tap the first button. Any ideas on how to do this? I have ARC disabled, other 'solutions' i've come across keep giving me errors.

Thanks all, would appreciate some guidance here.

First of all, `exit(0)`: never! Tip: http://stackoverflow.com/questions/14335848/exit-application-when-click-button-ios Then, to instance a new UIViewController, Apple Doc should be useful. — Larme, Jan 21 '13 at 11:51

what i have understand is you have screen A and B . You have alert view on screen view .And if you click one of the button then it should go in B .Right ? — V-Xtreme, Jan 21 '13 at 11:58

If your current viewcontroller is in a Navigation Controller:

UIViewController *myViewController = [[UIViewController alloc] init];
myViewController.title = @"My First View";
//to push the UIView.
[self.navigationController pushViewController:myViewController animated:YES];

And never use exit(0)!

Would it be possible to make it a modal view controller? – iPwnTech Jan 21 '13 at 12:02

- (void)alertView:(UIAlertView *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
if (buttonIndex == 0)
{

 NewViewController *controller=[[NewViewController alloc]initWithNibName:@"NewViewController" bundle:nil];
            self.modalTransitionStyle=UIModalTransitionStyleCrossDissolve;
            [self presentViewController:controller animated:YES completion:nil];



}

drasick has given sufficient answer but if you need to use model view controller refer above.

Receiving 'unknown receiver' and 'unknown type name', my view controller name is webviewviewcontroller, any ideas? – iPwnTech Jan 21 '13 at 12:17
forward declare class @class className instead on #import in the .h file and do #import in .m to avoid circular dependancies – V-Xtreme Jan 21 '13 at 12:36

Use:

UIViewController *yourViewController = [[UIViewController alloc] init];
[self.navigationController presentModalViewController:myViewController animated:YES];

to push a modalViewController.(This is depriciated in iOS 6, but will work)
