Which Scheme URLs need to be added to the .plist of an iOS 9 app in order to authorize using the OK app?

Question

iOS

I found ok:// okauth:// ok310272:// maybe some more needed?

Answer 1

ok310272:// is a possible address for a reverse redirect from authorization if the application id is 310272. No more should be registered. See examples from https://github.com/apiok/ok-ios-sdk
By registering ok:// or okauth://, authorization will simply not work for you.
