Facebook iOS SDK. Native Auth after user taps "Don't Allow"

Question

When using Native Auth, how can the app ask for auth permission again if the user has already pressed "Don't Allow"?

I made a simple app that connects to Facebook using the Native auth dialog box. When testing, I pressed "Don't Allow". Now, everytime I press the Login button I created, it throws an error, saying that auth was cancelled. In Settings.app, my app is turned off under Facebook. Reinstalling the app doens't help. How can I make the app ask for auth permission again, when the user taps "Login"?

Thanks in advance.

Unfortunately, you can't. This is IMO a bad design by Apple. Feel free to file a radar about it. In the meantime you'll have to tell your users how to go to the settings app and turn on your app. Each app has a toggle to turn off or on access to that Facebook account.
