Sign out of GC.
You will be prompted to login to GC. Select cancel.
Exit and restart game, and when GC prompt appears again, select cancel.
Do this again one more time.
After the third time, GC will prompt you if you want to disable it. Select yes.
GC will no longer prompt you when you start your game. This always works. I've confirmed it, as have others.
But there is one problem. If you sign into the App Store or iTunes, that will automatically sign you into GC. For example, if you go to the App Store and install a new app, the App Store will prompt you for your login ID and password. Entering that information will also automatically log you back into GC. Yes, it's brain dead, but this illogical and unwanted behaviour doesn't surprise me given how anal Apple is.
Game center also does not remain disabled. I've found that with Angry Birds seasons at least, every time the game reboots, you are again prompted to sign into Game Center. Cancel three times to disable it and it does disable, until the game restarts again. Then you have to go through it all over again.
I have also removed that game from the game center account, but it continually reassociates itself. Basically it refuses to take no for an answer.
I think my biggest concern is what else is Rovio accessing(the makers of Angry Birds)? They get my password to my Apple ID no matter what I do, which means they theoretically have access to my iTunes account and any payment associated with that. They've apparently found a way out of the sandbox and what else can they access?
BeJeweled seems to remain disabled. Another game that I have that's a game center game is geared towards kids so I think they have or maintain a higher privacy standard. It too remains disassociated and signed out. Only Angry Birds seasons continues to force itself upon me.
The only thing that's kept me from deleting angry birds is if they ever fix it I would lose two years of progress. Although due to this, I'm barely playing it so it's getting to the 'no big loss' point.
I don't want to social game. I especially don't want to let my 6 year old niece social game. This just seems like a major privacy issue and the only comments I get back from Apple or Rovio are silence or canned responses.
This was posted in another thread, and it works.
Log out of GC.
Create a bogus GC account - one you don't care about, and one that isn't the same as you use for your Apple ID for the App Store or Itunes Store.
Log into bogus account
Log out of bogus account. GC will think this is the account you use for GC.
Start up your game and when asked to login to GC, press cancel. Do this sequence three times.
After third time, GC will ask if you want to disable it. Select yes.
Voila. As long as you don't log into the bogus account, GC will remain disabled. You can login to App Store or Itunes store with your regular account and download/install apps and songs and no longer have issues with GC. GC will ignore this account and will always associate the bogus account (which you will never use) with it.
Everytime I think I've disabled Game Center it pops back on if I make a music or app purchase. This is a serious flaw in the OS. Apple should be ashamed. Absolutely invasive and more than annoying. I DO NOT WANT TO USE GAME CENTER. This issue, unfortunately will be ignored by Apple. Are you listening Apple? No? Thought not. ********.
Look up a couple posts. I explained exactly how to get around this. It works for mutiple people, and has been working for me for a couple months now.
Don't expect Apple to make a change. They have a very closed business model and providing options for users (aka Windows/Linux) doesn't fit into that model.
That solution above does work. I've done it. No, you can't turn GC off, but you do anonymize it. So if the reason it won't turn off is data mining (likely in hte hope of spamming you with game recommendations) then at least it's mining false data.
I just won't spread it around or promote it because I fear, if the data mining is deliberate, the hole will be plugged. That code will be incorproated into the system to defeat this. (I guess if that happens it can confirm the suspicion that GC is nothing more than a data mining tool)
I've also noticed that it's not all games. Some respect your privacy (especially ones geared towards kids), while others are almost belligerant in forcing GC on you.
Apple is not here on this forum. If you want to let them know what you think about game center, use the contact us link below and send them some feedback. I've also let game developers know just how much i 'adore' their practices.
No, the solution does not work - iPad and iPhone - both running iOS6.x
What worked for me on the iPhone is to clear the email address in the gamecenter box, and put in a made up ID. Then click submit, then cancel. Disappeared for now. The 'three times' thing does not work. When using SongPop - gamecenter pops up every single time. So, adding the made up ID worked for me.
Better remove this in iOS7, Apple.
