你使用模拟器吗?

在模拟器中，不支持远程通知.

In a simulator, remote notifications are not supported.

示例代码:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    let pushSettings = UIUserNotificationSettings(forTypes: [UIUserNotificationType.Badge ,UIUserNotificationType.Sound ,UIUserNotificationType.Alert], categories: nil)
    application.registerUserNotificationSettings(pushSettings)
    return true
}

func application(application: UIApplication, didRegisterUserNotificationSettings notificationSettings: UIUserNotificationSettings) {
    application.registerForRemoteNotifications()
}

func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
    let token=deviceToken.description
    print(token)
}

func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
    print(error)
}

Xcode 说:

Error Domain=NSCocoaErrorDomain
Code=3010 "REMOTE_NOTIFICATION_SIMULATOR_NOT_SUPPORTED_NSERROR_DESCRIPTION"
UserInfo={NSLocalizedDescription=REMOTE_NOTIFICATION_SIMULATOR_NOT_SUPPORTED_NSERROR_DESCRIPTION}
