iOS Facebook使用SDK 4.12登录

Question

I am banging my head against getting Facebook Login to work wen upgrading to SDK 4.12. It was working fine in our (very) old 3.x implementation.

I have followed every bit of documentation I can find, and have re-checked my code over and over. Hopefully someone can provide some insight!

My issue is, it simply does not allow for a 1 click single sign on. When the FBSDKLoginButton is clicked, it always brings up the Facebook web dialog to enter credentials. This is being run on an actual device, with the Facebook app installed and logged in.

Why can I not get it to simply allow access without signing in to Facebook?

Simple code is as follows:

FBSDKLoginButton *loginButton = [[FBSDKLoginButton alloc] init];
loginButton.readPermissions =
@[@"public_profile", @"email", @"user_friends"];
loginButton.delegate = self;

Delegate callbacks all working fine.. the only issue having to enter user/password on the Facebook pop up.

(My device IS logged into Facebook in it's settings as well.)

Thank You!

Solution to this for those who like the old way.. use SDK 4.5.1. It has the Facebook login flow as it was intended. You may lose a few of the newest features available in 4.6, but it has solved all of our issues.
