I have found another related issue with posting an achievement. When you post an achievement on iOS7 the "Achievement completed" message is also shown when the percentage is not 100%. My app currently shows an endless loop of completed messages, when in reality the achievement is not completed yet.
I suggest to only show this message when the given percentage is 100.
Thank you Lee for the quick fix of #25.
