iOS 的 GCM，从不调用 gcm 连接处理程序
GCM for iOS, gcm connection handler is never called
我正在我的应用程序中实施 Google 云消息传递。我遵循了 google 文档中给出的 tutorial。我可以使用 HTTP POST 请求向我的设备发送通知，但问题是在 applicationDidBecomeActive 中，如 google 所示，我尝试连接 gcmService 但 connectionHandler 块永远不会叫.
我的 AppDelegate 中的 applicationDidBecomeActive 函数
func applicationDidBecomeActive(application: UIApplication) {
GCMService.sharedInstance().connectWithHandler({
(NSError error) -> Void in
if error != nil {
print("Could not connect to GCM: \(error.localizedDescription)")
} else {
self.connectedToGCM = true
print("Connected to GCM")
self.subscribeToTopic()
}
})
}
有人解决过这个问题吗？

您是否检查过您是否已在 plist 中定义了 NSAppTransportSecurity 密钥。
您的代码中有几个问题。
首先，你需要在didFinishLaunchingWithOptions方法中调用GCMService.sharedInstance().startWithConfig(GCMConfig.defaultConfig())，但是你只在didRegisterForRemoteNotificationsWithDeviceToken方法中调用了
其次，您应该在 didFinishLaunchingWithOptions 方法中的 application.registerUserNotificationSettings() 之后调用 application.registerForRemoteNotifications()。
AppDelegate.swift 文件有一个 sample GCM project for iOS available, you can follow the sample implementation，这样您的应用程序才能正常运行。
您还可以通过执行 pod try Google 通过 Cocoapods 获取 GCM iOS 示例项目，您可以访问 this documentation 了解更多详情。
已编辑：
您应该将 didFinishLaunchingWithOptions 中的行替换为以下内容（注意您应该使用 let gcmConfig = GCMConfig.defaultConfig() 和 gcmConfig.receiverDelegate = self）：
// [START_EXCLUDE]
// Configure the Google context: parses the GoogleService-Info.plist, and initializes
// the services that have entries in the file
var configureError:NSError?
GGLContext.sharedInstance().configureWithError(&configureError)
assert(configureError == nil, "Error configuring Google services: \(configureError)")
gcmSenderID = GGLContext.sharedInstance().configuration.gcmSenderID
// [END_EXCLUDE]
// Register for remote notifications
let settings: UIUserNotificationSettings =
UIUserNotificationSettings( forTypes: [.Alert, .Badge, .Sound], categories: nil )
application.registerUserNotificationSettings( settings )
application.registerForRemoteNotifications()
// [END register_for_remote_notifications]
// [START start_gcm_service]
var gcmConfig = GCMConfig.defaultConfig()
gcmConfig.receiverDelegate = self
GCMService.sharedInstance().startWithConfig(gcmConfig)
// [END start_gcm_service]
return true
