我用它来注册通知:

if application.respondsToSelector("registerUserNotificationSettings:") {
                let types:UIUserNotificationType = (.Alert | .Badge | .Sound)
                let settings:UIUserNotificationSettings = UIUserNotificationSettings(forTypes: types, categories: nil)

                application.registerUserNotificationSettings(settings)
                application.registerForRemoteNotifications()

            } else {
                // Register for Push Notifications before iOS 8
                application.registerForRemoteNotificationTypes(.Alert | .Badge | .Sound)
            }

但它并不适用于iOS 9.

在部署FCM云消息传递之后,这是GCM云消息传递的升级版本,如https://developers.google.com/cloud-messaging/ios/client所述,因此我们使用pod将https集成到我们的应用中,如上所述https:// firebase.google.com/docs/cloud-messaging/notifications我跟进本教程中的每一步都是在状态背景状态和活动状态下收到远程通知的情况,但我遇到的主要问题是通知确实出现在通知栏中这里是我正在使用的代码

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {



    float ver = [[[UIDevice currentDevice] systemVersion] floatValue];

    if(ver >= 8 && ver<9)
    {
        if ([[UIApplication sharedApplication] respondsToSelector:@selector(registerUserNotificationSettings:)])
        {
            [[UIApplication sharedApplication] registerForRemoteNotifications];
            UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert) categories:nil];
            [[UIApplication sharedApplication] registerUserNotificationSettings:settings];

        }
    }else if (ver >=9){

        [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];

        [[UIApplication sharedApplication] registerForRemoteNotifications];


    }
    else{
        //iOS6 and iOS7 specific code
        [[UIApplication sharedApplication] registerForRemoteNotificationTypes:UIRemoteNotificationTypeBadge|UIRemoteNotificationTypeAlert];
    } …
