presentmodalviewcontroller navigationcontroller

I am creating a Navigation based iPhone applicat开发者_运维技巧ion.

In that I have called a UiViewController using presentModalViewController. After that, the ViewController becomes visible. From that ViewController I need to call another ViewController using the sample presentModalViewController. Is this possible or not?

What do you mean by "call another uiviewcontroller"? (It really helps if you can be more detailed in your question.) If you mean, "slide in another view controller", then:

MyNewViewController *myNewViewController = [[MyNewViewController alloc] initWithNibName:@"MyNewViewController" bundle:nil];
[navigationController pushViewController:myNewViewController animated:YES];
[myNewViewController release];

...where:

• MyNewViewController is the new view controller class that you want to slide in (the above code assumes you have an XIB file for the view controller class).
• navigationController points to the current navigation controller. You'll have to replace it with something like [self navigationController], depending where you are in the view hierarchy.

U might be using following line to present a view controller.

//assume name of viewController which u want to present is "myViewController"
    [self.navigationController presentModalViewController:myViewController animated:YES]

If you want to push an other ViewController or present an other ViewController then u will need to replace above line with following lines.

//[self.navigationController presentModalViewController:myViewController animated:YES];

UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:myViewController];
navigationController.navigationBarHidden = YES; //if u want to show navigation bar then remove this line
[self presentModalViewController:navigationController animated:YES];

After using above code you can present or push other view controllers within presented view controller.

Hope it will solve your problem :)
