要制作哪种类型的ViewController？

Question

I have a button that when pressed, brings up a modal view.

Lets call this modal view "AboutViewController".

My question is, what type of viewController should this be. I set up the rest of my app a while ago and don't remember exactly how I got it setup.

I already have a TabBar that is present so Ill just make it viewable at the bottom, that shouldn't be an issue.

But I want it to be a navController but I want it to be separate from the nav stack of the rest of my app, I will then add a UITable, etc in IB.

Answer 1

Just do:

UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:AboutViewController];
[self presentModalViewController:nav animated:YES]; 

Answer 2

I assume you have a class for the Modal View? Say you called it AboutViewController.

You would just need to do:

    AboutViewController *viewController = [[AboutViewController alloc] init];
    UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:viewController];
    [viewController release];

    [self presentModalViewController:navController animated:YES];
    [navController release];

The nav stack for the Modal View will be separate from your other nav stack and your Modal View Controller will handle it.

Answer 3

You can add that view as a PresentModalViewController. You have to add that view as same as we are adding the other view in our project.

And then after when button is pressed you have to write below code to show that view.

AboutViewController *aboutViewController = [[AboutViewController alloc] initWithNibName:@"AboutViewController" bundle:nil];
[self presentModalViewController:aboutViewController animated:YES];
[aboutViewController release];
