1) In the Game Center app on the device, a game I purchased from the app store (i.e. Temple Run) appeared in the sandbox along with the game I was trying to debug. So what? Got there? I have a few other app store games, the game center function is not displayed, so not all the content on my device is displayed.
2) The game I am developing has achievements and leaderboards. The code submitted for both seems to work, but only my achievements appear in the Game Center app. It says “No leaderboard” instead of showing my leaderboard. However, if I run the code that retrieves the leaderboard information, It will work as expected and I will get my score.
3) The Game Center app in the emulator does not say “No leaderboard”. It has a leaderboard for my game, but it says “No score”. On the leaderboard details screen, it shows that my ranking is 1st among 1 friend and 2nd among 2 players, and in the detailed information it shows my test game Actual score.
4) The game center application of the emulator says that I have no achievements, even though the game center application of the device displays the achievements correctly. Does the Game Center application of the emulator simulate Game Center Server and does not match Real Game Center server communication?
5) Am I counted as one of my “friends” even if I have not done anything to become a friend (explain #3 above)?
6) The leaderboard screen on the device seems to be working at first glance, but I just realized that the score it shows is numerically wrong! what is that? Maybe they are left over from yesterday or other time?
2) I have similar problems, and I think some problems are related to the sandBox account. For example, when I download from When one device sends scores, I can’t see any uploaded leaderboard scores, as long as the second device submits scores, they will all appear in the leaderboard.

I use very simple code, modeled after the code in Strougo& Wendridge, but what I want to figure out is that weird things are happening. Several of them :

1) Game Center accounts sometimes fall into sandbox mode. One solution is to log out from the Game Center application and log in from the game (in this case
