Question

这些是我的设置：

project settings

和

Project settings2

这是我的appDelegate

#if defined(__IPHONE_10_0) && __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_10_0

#endif

@implementation AppDelegate 
NSString *const kGCMMessageIDKey = @"gcm.message_id";

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

 #endif
    }

    [[UIApplication sharedApplication] registerForRemoteNotifications];
    // [END register_for_notifications]
}

  [FIRApp configure];

加上所有这些app delegate回拨

虽然我在控制台中收到了消息，但我无法在后台获取横幅和通知。（- (void)applicationReceivedRemoteMessage:(FIRMessagingRemoteMessage *)remoteMessage已被触发）。

也没有声音，所有配置文件都已完成，以防万一。

Answer 1

您需要在if语句之前调用[FIRApp configure]！

Answer 2

好的解决了。您需要在Apple开发人员站点中设置应用程序ID，并在开发和分发上启用推送通知（不要伪造捆绑ID必须与Xcode上的捆绑ID相匹配）。之后，您需要为此创建配置文件应用程序ID并将其安装在您的mac.Last但最重要的是您需要在Firebase控制台中放入从钥匙串访问生成的p12文件。在firebase控制台中，概述旁边有一个灰色齿轮按钮。您选择该选项，然后选择云消息传递选项卡，并在展开推送通知认证并导出p12文件时上载在钥匙串访问中生成的p12证书文件。您需要输入密码并将其上传到firebase。

为什么我在控制台ios10.2上接收消息时没有获得横幅和后台模式推送通知
