使用PresentModalViewController時，來切換下一個 ViewController， 如何還可以使用 navigationController

NextViewController *nextViewController=[[NextViewController alloc]initWithNibName:@"NextViewController" bundle:nil]; UINavigationController *navBar=[[UINavigationController alloc]initWithRootViewController:nextViewController]; [self.navigationController presentModalViewController:navBar animated:YES]; [navBar release]; [nextViewController release]; 參考來源：http://stackoverflow.com/questions/6056726/presentmodalviewcontroller-not-showing-navigation-bar-on-next-view
