我的AppDelegate.Swift是

class AppDelegate: UIResponder, UIApplicationDelegate, GIDSignInDelegate {
public func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!, withError error: Error!) {
   if (error == nil) {

    let userId:NSString = user.userID as NSString;                  // For client-side use only!
    let idToken: NSString = user.authentication.idToken as NSString; // Safe to send to the server
    let fullName:NSString = user.profile.name as NSString;
    let givenName:NSString = user.profile.givenName as NSString;
    let familyName:NSString = user.profile.familyName as NSString;
    let email:NSString = user.profile.email as NSString;
    print(userId)
    print(userId,idToken,fullName,givenName,familyName,email)
    }

   else {
    print("\(error.localizedDescription)")
    }
}

var window: UIWindow?

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

    let kclientID:NSString = "107731993306-xxxxxxxxxxxxxxxxx.apps.googleusercontent.com"

   GIDSignIn.sharedInstance().clientID = kclientID as String!

    GIDSignIn.sharedInstance().delegate = self
    return true
}


func application(application: UIApplication,
                 openURL url: NSURL, options: [String: AnyObject], annotation:Any, sourceApplication:String?) -> Bool {

    return GIDSignIn.sharedInstance().handle(url as URL!, sourceApplication:sourceApplication, annotation: annotation)
} 

请给我解决方案。为什么会崩溃？

Answer 1

正如错误清楚地说明，您的应用程序缺少对url方案的支持。

将以下方案添加到info.plist中

<key>CFBundleURLTypes</key>
<array>
    <dict>
        <key>CFBundleTypeRole</key>
        <string>Editor</string>
        <key>CFBundleURLSchemes</key>
        <array>
            <string>***Your bundle ID***</string>
        </array>
    </dict>
    <dict>
        <key>CFBundleTypeRole</key>
        <string>Editor</string>
        <key>CFBundleURLSchemes</key>
        <array>
            <string>com.googleusercontent.apps.107731993306-6s44u18onibp6gi0ddj94si1aifshhg6</string>
        </array>
    </dict>
    <dict>
        <key>CFBundleTypeRole</key>
        <string>Editor</string>
        <key>CFBundleURLSchemes</key>
        <array>
            <string>***Something here***</string>
        </array>
    </dict>
</array>

检查此网址是否为您的id => https://developers.google.com/identity/sign-in/ios/start-integrating

您的info.plist应该看起来像 - >

Answer 2

您必须为项目添加URL方案

1. 打开项目配置：双击左侧树视图中的项目名称。从TARGETS部分选择您的应用，然后选择Info选项卡，并展开URL Types部分
2. 点击+按钮，然后添加网址方案-com.googleusercontent.apps.107731993306-6s44u18onibp6gi0ddj94si1aifshhg6

Answer 3

仔细检查：

在AppDelegate反向DNS：

GIDSignIn.sharedInstance().clientID = "536164374389-ivga9a9at2g31nfmhpvdyhc98yf6afnr.apps.googleusercontent.com"

在Info.plist直DNS：

<string>com.googleusercontent.apps.536164374389-ivga9a9at2g31nfmhpvdyhc98yf6afnr</string>

Answer 4

你必须添加反向客户端ID而不是正常的客户端ID。

Answer 5

Xcode为您提供了一个字符串 - 将其放在此处，如下图所示
