Question

I just copied/pasted this code from the apple dev libary into xcode, and xcode gives me a lot of basic syntax errors..

- (void) authenticateLocalPlayer
{
    GKLocalPlayer *localPlayer = [GKLocalPlayer localPlayer];
    localPlayer.authenticateHandler = ^(UIViewController *viewController, NSError *error){
         if (viewController != nil)
         {
             [self showAuthenticationDialogWhenReasonable: viewController
         }
         else if (localPlayer.isAuthenticated)
         {
             [self authenticatedPlayer: localPlayer];
         }
         else
         {
             [self disableGameCenter];
         }
     }];
}

Am I doing something wrong?

Answer 1

I suspect that you need to be targeting iOS6 and are not. My compiler also generates errors if I target iOS 5.x. Docs state that availability of the @property authenticateHandler is iOS6 only.

Also, syntax error missing closing bracket and semicolon after viewController in the first if clause of the block.
