GAME CENTER

Same problem here...

I got the same problem, but it is fixed after I restore the firmware.

It is still working after restoring all backup data, so the cause is still a mystery.

I have the same problem. Please advice how to solve this issue

Exactly the same problem

I kinda have the same problem... except that I can log in, it just won't load. It says "loading..." but does not do so. I do a reset and it would work fine for a bit. But having to do that EVERY time I want to use Game Center is too much. Is there anything that can be done, or is this just something apple doesn't care to fix like the "Storage Almost Full You can manage your storage in Settings" spam that pops up frequently even though my storage is not almost full?

I had this problem before the latest update

I found by logging one if my devices out of Game Center (iPhone/iPad)

generally it was resolved

although the occasional reboot was req'd

However, now it logs in automatically

even without credential

or deliberately false credentials...

maybe this might help

best if luck!

Close all open apps by double-tapping the home button, then swiping up and off the screen with the app window (not the smaller icon).

Reset your device: hold down the home button along with the sleep/wake button until the screen goes black and you see the Apple, then let go. (No data loss)

Thank you! I've been scouring the internet desperately trying to find a solution to my Game Center login problem, and I'm so grateful I was able to come across your suggestion. So many other proposed solutions just didn't work. And here you gave this solution to someone a year and a half ago. I will do my best to pass it on to anyone else whom I see having this problem. God bless you!

我找到了最终的解决方案。

我看到有人通过修改系统语言解决了这个问题，因此我意识到原因可能和语言有关。

后来我发现在/var/mobile/Library/GameKit/Data里的文件夹是以语言分类的。

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。

我认为导致问题的原因是无效的缓存数据。cocoa无法解析必要的缓存数据而抛出异常信息。

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!
