如何修复无法获取默认令牌错误？

Question

我在iphone中安装后出现此错误.

Answer 1

使用Xcode8,修复方法是简单地启用功能中的Keychain Sharing

打开app.xcworkspace文件,选择Target> Capabilities> Enable'Keychain sharing'

Answer 2

此问题的可能原因:

1. 设备日期未设置为当前日期.
2. 捆绑ID与您在GoogleService-Info中设置的捆绑ID不同.
3. 在Firebase控制台上上载的.p12证书不正确.

Answer 3

确保:

• 捆绑ID与您在GoogleService-Info中设置的捆绑ID相同
• 代码签名参数(Target => Build Settings => Code signing)更正并与您在Firebase中设置的p12证书文件相匹配.

此外,你必须遵循这些tutos:

• 通知: https ://firebase.google.com/docs/notifications/ios/console-audience
• 配置: https ://firebase.google.com/docs/ios/setup

并且不要忘记向用户请求权限只是在您的应用程序中添加(例如在AppDelegate文件中,或在其他ViewController中):

let notificationTypes: UIUserNotificationType = [UIUserNotificationType.Alert, UIUserNotificationType.Badge, UIUserNotificationType.Sound]
let pushNotificationSettings = UIUserNotificationSettings(forTypes: notificationTypes, categories: nil)
application.registerUserNotificationSettings(pushNotificationSettings)
application.registerForRemoteNotifications()
