I implemented facebook sdk in my project and everything is set up exactly as shown in the https://developers.facebook.com/docs/facebook-login/ios/v2.0 manual , including the info.plist file.
FacebookAppID, FacebookDisplayName and URL types set (see image)
Everything works when I use the login application to enter facebook or enter the browser, but when I add an account, you should be present in the iOS login dialog box, nothing happens, the log displays User cancelledevery time I press the Facebook login button into the system.
I have done several projects before using the facebook login function and I have not experienced this error. I think something is missing from me, but for some reason I cannot understand. The appId and item 0 applications with the prefix have the same number, and the display name is exactly copied from the FB developer.
The strange problem that I noticed here is that when I first install the application on the device with the FB account settings in the settings, I can click it once ... nothing happens, and after the second press the application automatically shuts down in the settings > Facebook.
UPDATE. Facebook SDK ( SDK , ... , SDK public_profile basic_profile, SDK), FB SDK, mistery:)
