After update iOS 9 and Facebook sdk 4.6 the login window not open

Question

I update my Xcode to 7 , and Facebook to 4.6 sdk.

this My warning :

Warning: Attempt to present <FBSDKContainerViewController: 0x159337700> on <UIAlertController: 0x159262700> whose view is not in the window hierarchy!

in My project the BitCode is NO - because if I turn it to Yes I got this Error :

ld:'/Users/MyName/Desktop/MyProjectName/ProjectName/ProjectName/Resources/Frameworks/Fabric.framework/Fabric(Fabric.o)' does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

this is the parse method :

-(void)signInWithFacebookClicked
{
NSArray *permissions = [NSArray arrayWithObjects:@"email",@"user_friends", nil];
[PFFacebookUtils logInInBackgroundWithReadPermissions:permissions block:^(PFUser *user, NSError *error)
 {
     if (!user) // The user cancelled the Facebook login
     {
         NSLog(@"Uh oh. The user cancelled the Facebook login.");
     }
     else if (user.isNew) // New user (not stored on DB) - User signed up and logged in through Facebook
     {
         [self handleNewUser];
     }
     else if (user) // the user is exist at DB
     {
       // the user is exist at DB  
     }
     else if (error)
     {
        // showAlertOfSomethingWentWrong
     }
 }];
}

this is FBSDKGraphRequest :

-(void)handleNewUser
{

FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:@{@"fields": @"friends, first_name, gender, last_name, link, name, verified, picture, email"}];
[request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error)
 {
     NSMutableDictionary *userData = (NSMutableDictionary *)result;
}];

my problem is that that line :

[PFFacebookUtils logInInBackgroundWithReadPermissions:permissions block:^(PFUser *user, NSError *error)

the run never go into this block in iPhone , in simulator this work fine.

Answer 1

I had a similar problem where I was trying to show a login alert on top of FBSDKContainerViewController.

In this call

- (void)logInWithReadPermissions:(NSArray *)permissions
          fromViewController:(UIViewController *)fromViewController
                     handler:(FBSDKLoginManagerRequestTokenHandler)handler;

Facebook presents its own view controller and if you don't specify the fromViewController, "the topmost view controller will be automatically determined as best as possible."

In your case, it sounds like Facebook is trying to present on top of an alert that was dismissed, even if this is not the call being invoked.
