Question

I have tab bar and in view “A” and in “A” I have navigation controller. SO inside my navigation controller in “A” i called

[self presentModalViewController:modalView animated:YES]

But modalView shows under tab bar. How to show it above tab bar?

Answer 1

The cause of this is that the ancestor viewController is not correctly set.
for instance imagine:

UIViewController * myController = ... // a view controller without a proper ancestor

now:

myController.tabBarController == nil

Therefore:

[myController presentModalViewController:otherController];

Will fail (by showing up under the tab bar). The fix is to add myController to its ancestor via

[parentController addChildViewController:myController];

Now, parentController must be added to another controller in the same way and so forth until the root one is your tabController. This is only available in iOS 5+. If build for iOS 4 or earlier, you will have to work around this by making sure all of your controllers are directly added to either a UINav or UITab controller. If this is not possible, you will have to access the UITabBarController via a global variable.
