Question

I am implementing a protocol that has a method called fbDidExtendToken:.
For some reason, I get the warning that I am not implementing this method.
Why is this?

In my .h:

@interface AppDelegate : UIResponder <UIApplicationDelegate, FBSessionDelegate>
//...

in my .mm

@implementation AppDelegate
//...
-(void)fbDidExtendToken:(NSString*)accessToken
{

}

Error message is:

/Volumes/mchinen/scm/FindYourself/FindYourself/AppDelegate.mm:13:1:
warning: method in protocol not implemented [-Wprotocol,3]
/Volumes/mchinen/scm/FindYourself/src/Facebook.h:123:1: note: method
declared here [3]
– (void)fbDidExtendToken:(NSString*)accessToken

Answer 1

Looking in the protocol header file, it seems the entire method is

- (void)fbDidExtendToken:(NSString*)accessToken expiresAt:(NSDate*)expiresAt;

and the xcode warning only gave me the method name up to the first parameter, which I copied and pasted to implement, causing the warning.
