麻烦处理Google登录Swift 3 [英] Trouble handling Google sign in Swift 3
问题描述
我是iOS新手，在Swift 3中遇到了应用程序委托的URL处理问题，我真的可以使用一些指针。
$ b
下面的代码工作得很好在Swift 2.3中：
func application（application：UIApplication，
openURL url：NSURL，options：[String：AnyObject ]） - > Bool {
返回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）
}
当我粘贴swift 2.3代码直接从Firebase网站，Xcode提示我，很多方法已经改变。特别是，选项对象。
在Swift 2.3中，我可以使用<$ c $使用选项[UIApplicationOpenURLOptionsAnnotationKey]
Xcode提示我将其更改为 UIApplicationOpenURLOptionsKey.sourceApplication._rawValue as String 和 UIApplicationOpenURLOptionsKey.annotation._rawValue as String
然而，当我提出建议的更改时，Google会返回一个网址，但什么都不会发生。而不是重定向到应用程序，它进入本地谷歌网站，对我来说：www.google.co.nz
完整的Swift 3版本，我看起来像这个：
func application（application：UIApplication，
openURL url：NSURL，
options：[String ：AnyObject]） - > Bool {
print（UIApplicationOpenURLOptionsKey.sourceApplication._rawValue as String）
print（UIApplicationOpenURLOptionsKey.annotation._rawValue as String）
返回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！]
打印（UIApplicationOpenURLOptionsKey.sourceApplication._rawValue作为字符串）
print（UIApplicationOpenURLOptionsKey.annotation._rawValue as String）
返回GIDSignIn.sharedInstance（）。handle（url为URL !,
sourceApplication：sourceApplication，
annotation：annotation）
}
如果您在Google Sign In中使用多个URL Schemes， ：
func application（_ app：UIApplication，
open url：URL，
选项：[UIApplicationOpenURLOptionsKey：Any] = [：]） - > Bool {
$ b $ if（url.scheme！.isEqual（fbXXXXXXXXXX））{
返回SDKApplicationDelegate.shared.application（app，open：url，options：options）
} else {
返回GIDSignIn.sharedInstance（）。handle（URL为URL !,
sourceApplication：options [UIApplicationOpenURLOptionsKey.sourceApplication] as！String !,
annotation：options [ UIApplicationOpenURLOptionsKey.annotation]）
}
}
I am new to iOS and am having trouble with app delegate URL handling in Swift 3, and I could really use some pointers.
The below code works perfectly fine in Swift 2.3:
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 options object.
In Swift 2.3, I can access the source application using options[UIApplicationOpenURLOptionsSourceApplicationKey] and the annotation using options[UIApplicationOpenURLOptionsAnnotationKey]
Xcode prompts me to change it to UIApplicationOpenURLOptionsKey.sourceApplication._rawValue as String and 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
The full Swift 3 version I have looks like this:
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)
}
Xcode 8 Swift 3
If you are using multiple URL Schemes along with Google Sign In, use it like this:
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])
}
}
