Facebook login page showing blank page in IOS 9

Question

I am using FBSDKCoreKit (4.12.0) FBSDKLoginKit (4.12.0) first i am getting screen 1

This method is block is never called .

FBSDKLoginManager *login         


        

Answer 1

How i found solution for the above problem is

1)Earlier i have created a button and given FBLoginButton class and in action i wrote like

FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
[login logInWithReadPermissions:@[@"email",@"public_profile"] fromViewController:self handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
    //never called
}];

Modification for solution: Removed the FBLoginButton class and put only UIButton

2)Use both ios 8 and ios 9 methods like below written in AppDelegate.

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary *)options {
    return [[FBSDKApplicationDelegate sharedInstance] application:app
                                                          openURL:url
                                                sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey]
                                                       annotation:options[UIApplicationOpenURLOptionsAnnotationKey]];
}

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{

    return [[FBSDKApplicationDelegate sharedInstance] application:application
                                                          openURL:url
                                                sourceApplication:sourceApplication
                                                       annotation:annotation
            ];
}
