    As bizarre as this sounds, I read that someone with the same problem changed the language (in settings under international) and it worked .... I tried it and it worked too! I just changed language from English to Australian English.  Bizarre, right!

    其中只有我曾经尝试设置过的语言,所以我猜测它们是在第一次登陆Game Center时自动下载用于缓存数据的。



    只需将/var/mobile/Library/GameKit/Data重命名为/var/mobile/Library/GameKit/Data1或者直接删除该文 件夹。

    然后你就可以成功登录Game Center了!


    Firstly, I wanna say that I'm Chinese. I'm not very good at English.

    I have found the solution finally.

    I saw someone solve the problem by changing the language so I realized that the cause may be related with the language.

    And then I found the folders in /var/mobile/Library/GameKit/Data are catagrated by language.

    They are only the languages I have tried to set so I guess they may be downloaded automatically to cache data from the Game Center server at the first time when we logged in the Game Center. I thought the cause leading to the problem was the invalid cache data. The cocoa threw the exception information because it cannot parse the cache data required.


    Just RENAME /var/mobile/Library/GameKit/Data to /var/mobile/Library/GameKit/Data1 or DELETE it directly.

    And then you will log in the Game Center successfully!


    If someone can get what I meant, please help me to rewrite the solution in native English in order to help more people. Thank you!
