IOS – How to revoke 3rd-party apps Twitter integration on iOS 11

Developers access your Twitter accounts through the Accounts framework.

When an app requests access to your accounts, it uses the requestAccessToAccountsWithType:withCompletionHandler: method. (The only supported account type is currently ACAccountTypeIdentifierTwitter.) This grants access to all accounts of that type.

Therefore, unfortunately, apps can't request access to only a single account — you have to give access to all of your Twitter accounts.

If you are using iOS 6 (which I am, I can't get iOS 7 on an iPod 4) and the power is on, no matter what you're doing, the easiest way I found was to press the sleep button to put it on standby, press it again to turn it on, find the little camera icon that's next to the "slide to unlock" bar, drag it up to open the camera, and capture your moment.

Of course, this answer is very conditional: it only works if you have iOS 6, the device is either on or on standby, and you do not have a passcode (if you have a passcode, it makes you type it in before you can use the camera). But it works for me all the time, and I think this would work pretty well for others, too.
