ios - Facebook best auth flow with Accounts.framework -

-

I have read a lot of information about ACAccounts.framework and successfully in my application Have integrated.

Honestly all tutorials do not have good error flows and what to do next.

My following Athens works fine: 

  ACAccountStore * AccountStore = [[ACAquintStore Alok] Init]; AC Account Type * Account Type = [AccountStore Account Type with Identity Identifier: ACaccountTitIf IdentifiersBack]; NSDictionary * Options = @ {ACFacebookAppIdKey: kPSFacebookKey, ACFacebookPermissionsKey: @ [@ "Email"], ACFacebookAudienceKey: ACFacebookAudienceEveryone}; [AccountStore requestAccessToAccountsWithType: ACCOUNTTYPE Option: Option Completed: ^ (BOOL given, NSError * error) {if (given) {NSArray * accounts = [_currentUser.accountStore accountsWithAccountType: ACCOUNTTYPE]; _currentUser.facebook = [first object of the accounts]; Dispatch_assink (transmissions_fill_man_close ()), ^ {authSuccess ();}); } Else {dispatch_async (dispatch_get_main_queue (), ^ {authFailure (error); // to UIL ArtView to go to Settings and add an account? WHAT?}); }}];

If the user has an account in the settings and I trust it and I think about that user.

This actually works as expected, but is provided only when the user has an account in Settings . Otherwise I would show the warning to go to the user settings and add the account. I do not want to do that!

Then, the desired flow is:

  • If the user has an account in Settings , then get it via
  • If the user does not have an account in settings ->
  • If the user does not have the facebook app - go to safari login form> facebook book - then go back to the application
    • <

    I believe that <4> <4>

    So my main question is:

    • How can I get such a flow (
    • Do I need that Facebook IOS SDK
      • < Li> Can I merge credentials again with the Facebook session and add it to ACAccountStore manually

    thanks < / P>

<<>

/ Code> Settings in

If the user has settings -> not in the Facebook app
  • If the user has Go to Facebook app -> Safari Facebook login form - Enter credential -> Automatically go back to application
    • < P> What's really good is that I do not need to manually ACAccountStore (accounts in the iOS system), Facebook A DK does it for me, and I'm just relying on Facebook session (Ice Open).

    There was still an issue that the session disappears after application restart, and was solved by adding: 

      [FBSession openActiveSessionWithReadPermissions: allowLoginUI zero: NO completionHandler: ^ (FBSession * session, FBSessionState status, NSError * error) {}];

    Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project.
