我正在我的应用程序中实现 Google Cloud Messaging。我已经关注了tutorial谷歌文档中给出。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，我尝试与 gcmService 连接，但 connectionHandler block 从未被调用。
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()
}
})
}
有人解决了这个问题吗？

最佳答案
您的代码中存在一些问题。
首先需要在didFinishLaunchingWithOptions方法中调用GCMService.sharedInstance().startWithConfig(GCMConfig.defaultConfig())，但是你只在中调用了它>didRegisterForRemoteNotificationsWithDeviceToken 方法。
其次，您应该在 didFinishLaunchingWithOptions 方法中的 application.registerUserNotificationSettings() 之后调用 application.registerForRemoteNotifications()。
有一个sample GCM project for iOS可用，您可以关注sample implementation AppDelegate.swift 文件，以便您的应用程序正常工作。
您还可以通过Cocoapods通过pod try Google获取GCM iOS示例项目，您可以访问this documentation了解更多详情。
编辑:
您应该将 didFinishLaunchingWithOptions 中的行替换为以下内容(请注意，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
关于ios - 适用于 iOS 的 GCM，永远不会调用 gcm 连接处理程序，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/32689842/
