How to Set the Selected Item in a UITabBar From within the Code?

Question

I'm implementing UITabBar in my app. I managed making it work by implementing UITabBarDelegate in my header file and using

- (void)tabBar:(UITabBar *)tabBar didSelectItem:(UITabBarItem *)item

in my .m file (as explained in this tutorial).

Now, there are 3 scenarios in my app where I wish to set the selected UITabBarItem manually from within the code (and not based on user action):

• Upon viewDidLoad
• After didReceiveMemoryWarning
• In a certain case when the user is entering another view controller - when they get back, they should get back to a different tab than the one they clicked on.

Can anyone direct me to how this should be done?

Answer 1

The UITabBarController class has two properties for managing the selected tab, namely, selectedViewController and selectedIndex. Look into those in the reference.
