Question

I am an ios development newbie. I get an error when I try to do

tabBarController.delegate = self;

The error is “Assigning to ‘id UITabBarControllerDelegate ‘ from incompatible type “MyAppDelegate *””

What am I doing wrong?

Answer 1

You need to make your MyAppDelegate implement the UITabBarControllerDelegate protocol.

In the interface for MyAppDelegate mark it with @interface MyAppDelegate : NSObject <UIApplicationDelegate, UITabBarControllerDelegate>

The <UITabBarControllerDelegate> shows that you implement the UITabBarControllerDelegate protocol which is what is expected for the tabBarController.delegate
