Hi, i'm implementing a custom URL scheme, what i would like to know is in the AppDelegate i use the handleOpenURL

NSURL *)url function
In this function i check the url host, if this is correct i would like to change to a particular view but i'm not sure how to do it from the AppDelegate.
elsewhere in the app i would use the following to move to another view
Code:
self.viewOne = [[ViewOneViewController_iPhone alloc]initWithNibName:@"ViewOneViewController_iPhone" bundle:nil];
[self.navigationController pushViewController:self.viewOne animated:YES];
[self.viewOne release], self.viewOne = nil;
How do i change view from the AppDelegate
Thanks
Mick
