cannot find protocol declaration for UITabBarControllerDelegate

Question

I'm trying to implement a TabBarDelegate but I'm getting this error:

cannot find protocol declaration for UITabBarControllerDelegate

I add an NSObject class:

@interface tabBarDelegate : NSObject <UITabBarControllerDelegate>

any of you knows why I'm getting this error? or how resolve this error?

I'll really appreciate your help.

Did you remember to @import UIKit;?

The error is telling you that a declaration couldn't be found for the protocol UITabBarControllerDelegate.

So solve this, you need to be sure to import UIKit (the framework in which the protocol is declared).

@import UIKit;

Or, if all you need to access from UIKit in this file is the UITabBarControllerDelegate, you have the option of only importing UITabBarController's declarations.

@import UIKit.UITabBarController;
