How can I programmatically set selected tab of UITabBarController while also triggering shouldSelectViewController in UITabBarControllerDelegate

cocoa-touch, ios, uitabbarcontroller

Solution

If you have implemented `- (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController` in your tabBarController's delegate than you can call it manually.

[self.tabBarController.delegate tabBarController:self.tabBarController shouldSelectViewController:[[tabBar viewControllers] objectAtIndex:2]];
[self.tabBarController setSelectedIndex:2];

Hope this helps.

Problem

I'm trying to animate the transitions between tabs in my UITabBarController, which is working fine when I push on the tab buttons. However, when I switch tabs programmatically by calling ``` [self.tabBarController setSelectedIndex:2]; ``` in a swipe gesture recognizer, the shouldSelectViewController function is NOT being called in my UITabBarControllerDelegate delegate, and therefore my animation isn't being triggered. Is there a way to accomplish what I want? Can I programmatically trigger the tab switch differently perhaps so that the shouldSelectViewController function gets called?
