facebook and google login open in application by sfsafariviewcontroller - ios

Question

In my app user can login with facebook and google account. but when user click on facebook login or google login he will redirect to safari browser. So apple reject my app with below reason.
We noticed that the user is taken to Safari to sign in or register for an account, which provides a poor user experience. Next Steps To resolve this issue, please revise your app to enable users to sign in or register for an account in the app.
For resolving the issue I added facebook login behavior as the web "FBSDKLoginBehaviorWeb". Now when I open it, it is opening in the app only. but when I click on "Not Now" button on here is the facebook screen shot facebook it is crashing my app in the second time. Can anyone have answer to this issue? Also, can any one suggest me how do I solve the google sign on the issue too?

Answer 1

Try this :
Swift 4.0 snippet:
let loginManager = FBSDKLoginManager()
loginManager.logIn(withReadPermissions: ["email","public_profile"], from: self) { (result, error) in
if ((error) != nil) {
// Process error
} else if (result?.isCancelled)! {
// Handle cancellations
} else {
// If you ask for multiple permissions at once, you
// should check if specific permissions missing
if (FBSDKAccessToken.current() != nil)
{
FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"email, name"]) .start(completionHandler: { (connectioon, result, error) in
if error == nil
{
print(result);
}
})
}
}
}
Make sure you have added these below items in info.plist:
1.
<key>LSApplicationQueriesSchemes</key>
<array>
<string>fbapi</string>
<string>fb-messenger-share-api</string>
<string>fbauth2</string>
<string>fbshareextension</string>
</array>
2.
<key>CFBundleURLTypes</key>
<array>
<dict>
<key>CFBundleURLSchemes</key>
<array>
<string>fbxxxxxxxxxxxxxx</string>
</array>
</dict>
</array>
<key>FacebookAppID</key>
<string>xxxxxxxxxxxx</string>
<key>FacebookDisplayName</key>
<string>App name</string>
Note: iOS should be greater than iOS 9.0 or later to use SFSafariViewController.

facebookLogin.logIn(withReadPermissions: ["public_profile","email", "user_friends"], from:self, handler:
