}

To label the MainViewController as implementing the FBSessionDelegate protocol, you need to add the name of the protocol to the inside of a pair of angle brackets right before the curly braces:

#import <UIKit/UIKit.h>

#import “FBConnect/FBConnect.h”

@interface MainViewController : UIViewController <FBSessionDelegate> {

}

Also notice how you will need to add a new import statement to the MainViewController.h file. This instructs the compiler where to search to learn what makes the FBSessionDelegate work.

By adding the FBSessionDelegate to your MainViewController.h file, you are promising the compiler that it will be able to find any methods required by the FBSessionDelegate in your MainViewController.m file. That means at a minimum you will need to implement the didLogin method of the FBSessionDelegate in your MainViewController.m file.
