[login log:@"AccessToken" handler:^(id<FaceBook> object, bool trueOrFalse, NSError *error){
    // ... do whatever you'd like to do here.
}];

or...

void ^(handlerBlock)(id<FaceBook>, bool, NSError *) = ^(id<FaceBook> object, bool trueOrFalse, NSError *error) {
    // ... do whatever you'd like to do here
};

[login log:@"AccessToken" handler:handlerBlock];

or...

[login log:@"AccessToken" handler:nil];
