Use the appID to create the facebook object

_facebook = [[Facebook alloc] initWithAppId:kAppId];

decide what permissions you want to get

_permissions = [[NSArray arrayWithObjects: @"read_stream", @"offline_access",nil] retain];

and then login using

[_facebook authorize:_permissions delegate:self];

also dont forget to add the URL fb[appID] to the URL Types key in the info.plist file.
