我已经在iOS应用中实现了Firebase，并使用了仅数据有效负载。到目前为止，当应用打开或最小化时，我的自定义通知都可以正常工作。但是，当我轻扫应用程序时，我不再收到任何远程消息。滑动应用程序时，我不确定该应用程序是否已暂停或未运行。
到目前为止，我做了这样的事情：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
NSDictionary *userInfo = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
CustomNotif *notif = [[CustomNotif alloc] init];
[notif showNotification:userInfo];
}
CustomNotif是我创建的用于处理通知UI的类。我已经将aps有效负载设置为：
优先级：“高” 和可用内容：1
这是收到远程消息时得到的：
{
aps = {
"content-available" = 1;
};
body = "sample body";
"gcm.message_id" = "0:1538531666855542%d0cc52a4d0cc52a4";
iconURL = "http://www.shutterangle.com/wp-content/uploads/2012/04/bladerunner.jpg";
title = "Urgent action needed!";
}
我只有在打开或最小化应用程序时才能获得该有效负载。滑动或关闭应用程序时是否可以获取它？
我想添加更多信息。 。我尝试关闭该应用程序，并查看xcode中的设备日志，发现即使该应用程序已完全关闭，当有人发送远程通知时，该应用程序仍会触发；但是，我只是不知道如何获取数据。
以下是每次有人发送通知时显示的日志：

日志显示远程消息正在后台处理，但我不知道为什么它无法显示通知。我注意到这被称为“ connection：didReceiveIncomingMessage” 。
请帮助。
答案 0 :(得分：0)
您应该通过以下方法处理推送通知
- (void)application:(UIApplication *)application
didReceiveRemoteNotification:(NSDictionary *)userInfo
fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler;
此方法用于处理传入的通知。当您的应用程序在前台或后台运行时被调用。并且，如果您启用了远程通知后台模式，系统将启动您的应用程序并将其置于后台状态以处理notif（注意-如果用户强制退出该应用程序，它将不会重新启动该应用程序）。
