检查此代码，希望对您有所帮助

    -(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
        NSLog(@"%@", [userInfo description]);
        if (application.applicationState == UIApplicationStateBackground)
            {
              // Write your code for Background State
             }
        else if (application.applicationState == UIApplicationStateActive)
           {
              // Write your code here for Active state        
           }
        else if (application.applicationState == UIApplicationStateInactive)
           {
              // Write your code for Inactive State

           }

       }

【解决方案2】：

仅当您实施 VoIP 推送通知服务时，您才可以在不点击通知警报的情况下收到推送通知消息。 [VoIP 推送服务]

如果您使用 Apple PushKit 框架，您将在以下委托中获取消息数据：

- (void)pushRegistry:(PKPushRegistry *)registry didReceiveIncomingPushWithPayload:(PKPushPayload *)payload forType:(NSString *)type { NSDictionary *userInfo = payload.dictionaryPayload;NSLog("Your JSON here: %@",userInfo);
}
