keyboard - How to check the "Allow Full Access" is enabled in iOS 8?

Question

In iOS 8, when develop a custom keyboard and set RequestsOpenAccess property to YES in info.plist, there is a toggle button at Settings-> Add New Keyboard named "Allow Full Access". How does the custom keyboard code know that the user enabled or disabled this toggle?

Answer 1

UPDATE 08/23/2017 for iOS 10 compatibility:

func isOpenAccessGranted() -> Bool{
    UIPasteboard.general.string = "CHECK"
    return UIPasteboard.general.hasStrings
}

iOS 8:

-(BOOL)isOpenAccessGranted{
   return [UIPasteboard generalPasteboard];
}

Please note that the simulator will always tell you that you have Full Access so for this to work properly you need to run it from a device.
