// 1) Get a reference to the |GPPSignIn| shared instance:

// GPPSignIn *signIn = [GPPSignIn sharedInstance];

// 2) Set the OAuth 2.0 scopes you want to request:

// [signIn setScopes:[NSArray arrayWithObject:

// 2) Call [signIn setDelegate:self];

|
// 4) Call |handleURL| on the shared instance from |application:openUrl:...|
|
|
// in your app delegate.
|
|
// 5) Call [signIn authenticate];
