Trouble handling Google sign in Swift 3
提问by Clement
I am new to iOS and am having trouble with app delegate URL handling in Swift 3, and I could really use some pointers.
我是 iOS 新手，在 Swift 3 中处理应用程序委托 URL 时遇到问题，我真的可以使用一些指针。
The below code works perfectly fine in Swift 2.3:
以下代码在 Swift 2.3 中运行良好：
func application(application: UIApplication,
openURL url: NSURL, options: [String: AnyObject]) -> Bool {
return GIDSignIn.sharedInstance().handleURL(url,
sourceApplication: options[UIApplicationOpenURLOptionsSourceApplicationKey] as? String,
annotation: options[UIApplicationOpenURLOptionsAnnotationKey])
}
func application(application: UIApplication,
openURL url: NSURL, sourceApplication: String?, annotation: AnyObject?) -> Bool {
var options: [String: AnyObject] = [UIApplicationOpenURLOptionsSourceApplicationKey: sourceApplication,
UIApplicationOpenURLOptionsAnnotationKey: annotation]
return GIDSignIn.sharedInstance().handleURL(url,
sourceApplication: sourceApplication,
annotation: annotation)
}
When I paste the swift 2.3 code straight from the Firebase website, Xcode prompts me that a lot of the methods have changed. In particular, the optionsobject.
当我直接从 Firebase 网站粘贴 swift 2.3 代码时，Xcode 提示我很多方法已经改变。尤其是options对象。
In Swift 2.3, I can access the source application using options[UIApplicationOpenURLOptionsSourceApplicationKey]and the annotation using options[UIApplicationOpenURLOptionsAnnotationKey]
在 Swift 2.3 中，我可以使用访问源应用程序options[UIApplicationOpenURLOptionsSourceApplicationKey]和使用注释options[UIApplicationOpenURLOptionsAnnotationKey]
Xcode prompts me to change it to UIApplicationOpenURLOptionsKey.sourceApplication._rawValue as Stringand UIApplicationOpenURLOptionsKey.annotation._rawValue as String
Xcode 提示我将其更改为UIApplicationOpenURLOptionsKey.sourceApplication._rawValue as String和UIApplicationOpenURLOptionsKey.annotation._rawValue as String
Yet when I make the suggested changes, Google returns a URL, but nothing happens. Instead of redirecting to the app, it proceeds to enter the local google site, for me: www.google.co.nz
然而，当我进行建议的更改时，Google 会返回一个 URL，但没有任何反应。它没有重定向到应用程序，而是继续进入本地谷歌站点，对我来说：www.google.co.nz
The full Swift 3 version I have looks like this:
我拥有的完整 Swift 3 版本如下所示：
func application(application: UIApplication,
openURL url: NSURL,
options: [String: AnyObject]) -> Bool {
print(UIApplicationOpenURLOptionsKey.sourceApplication._rawValue as String)
print(UIApplicationOpenURLOptionsKey.annotation._rawValue as String)
return GIDSignIn.sharedInstance().handle(url as URL!,
sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication._rawValue as String] as! String!,
annotation: options[UIApplicationOpenURLOptionsKey.annotation._rawValue as String])
}
func application(application: UIApplication,
openURL url: NSURL,
sourceApplication: String?,
annotation: AnyObject?) -> Bool {
var options: [String: AnyObject] = [UIApplicationOpenURLOptionsKey.sourceApplication._rawValue as String: sourceApplication as AnyObject,
UIApplicationOpenURLOptionsKey.annotation._rawValue as String: annotation!]
print(UIApplicationOpenURLOptionsKey.sourceApplication._rawValue as String)
print(UIApplicationOpenURLOptionsKey.annotation._rawValue as String)
return GIDSignIn.sharedInstance().handle(url as URL!,
sourceApplication: sourceApplication,
annotation: annotation)
}

If you are using multiple URL Schemes along with Google Sign In, use it like this:
如果您将多个 URL Schemes 与 Google Sign In 一起使用，请像这样使用它：
func application(_ app: UIApplication,
open url: URL,
options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
if(url.scheme!.isEqual("fbXXXXXXXXXXX")) {
return SDKApplicationDelegate.shared.application(app, open: url, options: options)
} else {
return GIDSignIn.sharedInstance().handle(url as URL!,
sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication] as! String!,
annotation: options[UIApplicationOpenURLOptionsKey.annotation])
}
}

If you are using multiple URLSchemes for facebookand GoogleSignIn:
如果您为facebook和GoogleSignIn使用多个 URLSchemes ：
func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
let fbSignIn = FBSDKApplicationDelegate.sharedInstance().application(application, open: url, sourceApplication: sourceApplication, annotation: annotation)
let googleSignIn = GIDSignIn.sharedInstance().handle(url, sourceApplication: sourceApplication, annotation: annotation)
return fbSignIn || googleSignIn
}

For swift 5 Xcode 10.3 (Latest google signin)
对于 swift 5 Xcode 10.3（最新的谷歌登录）
@available(iOS 9.0, *)
func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any]) -> Bool {
let googleDidHandle = GIDSignIn.sharedInstance().handle(url)
return googleDidHandle
}
func application(_ application: UIApplication,open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
let googleDidHandle = GIDSignIn.sharedInstance().handle(url)
return googleDidHandle
}
To open signIn screen on Button click
要在按钮上打开登录屏幕，请单击
@IBAction func btnGoogleSigninClick(_ sender: AnyObject) {
GIDSignIn.sharedInstance()?.presentingViewController = self
GIDSignIn.sharedInstance()?.restorePreviousSignIn()
GIDSignIn.sharedInstance().signIn()
}

Try to perform any operations at function "signIn" in AppDelegate.
尝试在 AppDelegate 中的函数“signIn”处执行任何操作。
After Google sends you some data:
在 Google 向您发送一些数据后：
func signIn(signIn: GIDSignIn!, didSignInForUser user: GIDGoogleUser!,
withError error: NSError!) {
if (error == nil) {
// Perform any operations on signed in user here.
let userId = user.userID
// Perform some operation to change the scene.
// ........
}
else {
print("\(error.localizedDescription)")
}
}
Maybe the code below can give you some idea:
也许下面的代码可以给你一些想法：
let myStoryBoard:UIStoryboard = UIStoryboard(name:"Main", bundle:nil)
let protectedPage = myStoryBoard.instantiateViewControllerWithIdentifier("ProtectedPageViewController") as! ProtectedPageViewController
let protectedPageNav = UINavigationController(rootViewController: protectedPage)
let appDelegate:AppDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
appDelegate.window?.rootViewController = protectedPageNav
??? I reference from YouTube's video "Sign-in with Google Account button. Example in Swift. Video 2", that are provided from "Sergey Kargopolov".
？？？我参考了 YouTube 的视频“使用 Google 帐户按钮登录。Swift 中的示例。视频 2”，由“Sergey Kargopolov”提供。

While n.by.n answer is okay I saw a better answer in another thread (Swift 2.3):
虽然 n.by.n 答案没问题，但我在另一个线程（Swift 2.3）中看到了更好的答案：
if GIDSignIn.sharedInstance().handle(url, sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication] as! String, annotation: options[UIApplicationOpenURLOptionsKey.annotation]) {
return true
} else if something else {
return true
} else {
return false
}
