Code Change Needed in iOS 6

Some tips on your iOS code change needed for supporting iOS 6.

presentModalViewController

Starting from iOS 6, UIViewController deprecated this:

- (void)presentModalViewController:(UIViewController *)modalViewController animated:(BOOL)animated

Starting from iOS 5, the replacement is:

- (void)presentViewController:(UIViewController *)viewControllerToPresent animated: (BOOL)flag completion:(void (^)(void))completion

If you really need to support the older iOS 4 and below, and mix in the new replacement, you would need to check using respondsToSelector.

if ([self respondsToSelector:@selector(presentViewController:animated:completion:)])
    [self presentViewController:navController animated:YES completion:nil];
else
    [self presentModalViewController:navController animated:YES];

For older xib

Tab Bar not working

If after adding support for iOS6 and your UITabBar is not working anymore eg. does not respond to taps, it could be due to the xib from an older project.

You need to set the window object of your main xib to Full Size at Launch.

Error: UIViewControllerHierarchyInconsistency

This is again due to an older project.

You need to do this:

  1. Move main View out of View Controller:

  2. Delete View Controller from the XIB (it is not necessary since File’s Owner should be of its Class already)
