ios 消息通知

苹果的通知分为本地通知和远程通知，这里主要说的是远程通知

历史介绍

iOS 3 - 引入推送通知UIApplication 的 registerForRemoteNotificationTypes 与 UIApplicationDelegate 的 application(_:didRegisterForRemoteNotificationsWithDeviceToken:)，application(_:didReceiveRemoteNotification:)

iOS 4 - 引入本地通知scheduleLocalNotification，presentLocalNotificationNow:，application(_:didReceive:)

iOS 5 - 加入通知中心页面

iOS 6 - 通知中心页面与 iCloud 同步

iOS 7 - 后台静默推送application(_:didReceiveRemoteNotification:fetchCompletionHandle:)

iOS 8 - 重新设计 notification 权限请求，Actionable 通知registerUserNotificationSettings(_:)，UIUserNotificationAction 与 UIUserNotificationCategory，application(_:handleActionWithIdentifier:forRemoteNotification:completionHandler:) 等

iOS 9 - Text Input action，基于 HTTP/2 的推送请求UIUserNotificationActionBehavior，全新的 Provider API 等

ios 10 -

1. 相同的特性使用类似的API（之前的功能API使用方法类似但是还是稍有改变）
2. 内容扩展（支持附件和展示更多内容）
3. 本地通知和远程通知操作代码在相同调用路径（合并代理方法）
4. 简化代理方法
5. 更好的通知管理（支持通知查、改、删；增强本地通知管理，增加日历与地理位置事件的触发）
6. 应用内通知展示（之前App在前台的情况下收到通知不会UI展示）
7. 在Extensions中规划和操作通知（使更新通知内容和删除误发或过期的通知内容成为可能，另一个重要场景为端到端加密）
8. 引入通知Extensions

1.注册通知

2.接收到通知

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo

{
    DLog(@"iOS6及以下系统，收到通知");
    [self dealRemoteNotification:userInfo];
}

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler NS_AVAILABLE_IOS(7_0)
{
    DLog(@"iOS7收到通知");
    [self dealRemoteNotification:userInfo];

{
     NSDictionary *userInfo = notification.request.content.userInfo;
    [self dealRemoteNotification:userInfo];
}

- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler
{
    NSDictionary *userInfo = response.notification.request.content.userInfo;
     [self dealRemoteNotification:userInfo];
}

- (void)dealRemoteNotification:(NSDictionary *) userInfo
{
    NSDictionary *aps = [userInfo objectForKey:@"aps"];
    NSString *alert = [aps objectForKey:@"alert"];
    DLog(@"通知内容：%@", alert);
    DLog(@"收到推送消息：%@", userInfo);
    UIApplicationState state = [UIApplication sharedApplication].applicationState;
    switch (state) {
            
            // app正在前端运行
        case UIApplicationStateActive:
        {
            DLog(@"app active时可以回调此方法，但是手机通知栏没有通知跟声音");
        }
            break;
        case UIApplicationStateBackground:
        {
            DLog(@"UIApplicationStateBackground");
        }
            break;
            
            // app 在后台运行时点击远程通知
        case UIApplicationStateInactive:
        {
            DLog(@"点击通知图标 时点通知启动");
        }
            break;
        default:
            break;
    }
}

3.点击通知

如果APP处于未启动状态，点击通知栏启动APP，此时

• 若用户直接启动，lauchOptions内无数据;
• 若由其他应用程序通过openURL:启动，则UIApplicationLaunchOptionsURLKey对应的对象为启动URL（NSURL）,UIApplicationLaunchOptionsSourceApplicationKey对应启动的源应用程序的bundle ID (NSString)；
• 若由本地通知启动，则UIApplicationLaunchOptionsLocalNotificationKey对应的是为启动应用程序的的本地通知对象(UILocalNotification)；
• 若由远程通知启动，则UIApplicationLaunchOptionsRemoteNotificationKey对应的是启动应用程序的的远程通知信息userInfo（NSDictionary）；
• 其他key还有UIApplicationLaunchOptionsAnnotationKey,UIApplicationLaunchOptionsLocationKey,
  UIApplicationLaunchOptionsNewsstandDownloadsKey。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    NSURL *url = [options objectForKey:UIApplicationLaunchOptionsURLKey];
    if(url)
    {
    }
    NSString *bundleId = [options objectForKey:UIApplicationLaunchOptionsSourceApplicationKey];
    if(bundleId)
    {
    }
    UILocalNotification * localNotify = [options objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
    if(localNotify)
    {
    }
    NSDictionary * userInfo = [options objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
    if(userInfo)
    {
    }

}
