I'm attempting to integrate Game Center achievements into my game. I'm able to report GKAchievements at desired trigger points (i.e. various scores achieved). The problem I have is that reporting takes place as part of the Update function and continues to report the achievement and as a result the completion banner continues to display on repeat forever. I'm assuming I just need to check against if the achievement is completed or not and if it is completed I can break the loop. However, using achievement.isCompleted doesn't seem to work to do this. Any help, examples, ideas, would be awesome! Thanks
