IOS推送
推送
●iOS不允许App常驻后台
●提供服务器主动与用户相互的功能
●新闻类(热点新闻的推送)
●本地推送
●由本地应用触发(闹铃/待办事项)
●无需网络数据，提供和远程推送统一的交互
●远程推送
●普通远程推送
●静默推送
UserNotifications
UserNotifications
●iOS10之后统一UserNotificatiohsframework
●需要兼容低版本机型
●UNUserNotificationCenter单例管理全部推送
●统一的权限的申请
●在每次App启动时调用requestAuthorizationWithOptions
●系统在首次会出现弹窗，之后保存用户选择
●远程/本地Options相同
大体流程
- 开发者生成
- UNNotificationContent && UNNotificationTrigger
- 封装成UNNotificationRequest
- 然后给UNUserNotificationCenter
- 最后调用UNUserNotificationCenterDelegate
每个的作用
本地推送
UNNotificationContent
●推送内容
●标题/副标题/提醒/声音…
UNNotificationTrigger
●UNPushNotificationTrigger
●UNTimeIntervalNotificationTrigger
●UNCalendarNotificationTrigger
●UNL ocationNotificationTrigger
UNNotificationRequest
●封装Content 和Trigger为统一格式
●交给NotificationCenter处理
UNUserNotificationCenter
处理推送权限
●接收和移除止NotificaitonRequest
UNUserNotificationCenterDelegate
●即将展示推送的处理
●用户进行交互行为的处理
本地推送代码
- (void)checkNotificationAuthorization{
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
center.delegate = self;
[center requestAuthorizationWithOptions:UNAuthorizationOptionBadge | UNAuthorizationOptionSound completionHandler:^(BOOL granted, NSError * _Nullable error) {
//UNAuthorizationOptionBadge 右上角图标
//UNAuthorizationOptionSound 声音
//如果允许推送 granted == yes
if (granted) {
//本地推送
[self _pushLocalNotification];
});
}
}];
}
- (void)_pushLocalNotification{
UNMutableNotificationContent *content = [[UNMutableNotificationContent alloc] init];
content.badge = @(1);
content.title = @"我是推送标题";
content.body = @"我是需要推送的内容";
content.sound = [UNNotificationSound defaultSound];
//30秒推送一次 且不重复
UNTimeIntervalNotificationTrigger *trigger = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:30.f repeats:NO];
UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:@"_pushLocalNotification" content:content trigger:trigger];
[[UNUserNotificationCenter currentNotificationCenter] addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
//
}];
}
- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler{
completionHandler(UNNotificationPresentationOptionAlert);
}
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void(^)(void))completionHandler {
//处理badge展示逻辑
//点击之后根据业务逻辑处理
//[UIApplication sharedApplication].applicationIconBadgeNumber = 100;
//处理业务逻辑
completionHandler();
}
远程推送
推送数据不是由本地代码生成
●只需要接收和处理通知
●UNUserNotification CenterDelegate
需要服务器与APNs配合进行推送
●证书的配置/ Capabilities配置
●注册Device Token
●注册获得Device Token
●registerForRemoteNotifications
●UlApplicationDelegate回调注册结果
步骤
远程推送证书&代码实现
●注册Token/自定义发送
●接收推送消息进行业务处理
远程推送基本流程
权限申请，远程推送注册，本地推送的生成content选择Trigger生成request都变成了远程推送中用APNS+系统进行处理，最后接收处理，业务层回调
使用第三方推送平台：极光推送，信鸽推送，无需自己维护后台，全平台
远程推送内容
●Json 数据格式
●https://developer.apple.com/ibrary/archive/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/
CreatingtheNotificationPayload.html
远程推送调试工具
●Pusher
●搭建自己的服务器平台
APNs是啥
Apple Push Notification services
●APNs的作用
●防止每个App都要维持连接
●保证连接带来安全性和性能的挑战
●推送的流程
●App发送UDID和BundlelD给APNs，生成device Token
●App发送deviceToken给服务器
●服务器将信息和设备device Token发送给APNs
●APNs根据device Token进行推送
远程推送代码
因为在application获取register需要在主线程执行
dispatch_async(dispatch_get_main_queue(), ^{
[[UIApplication sharedApplication] registerForRemoteNotifications];
});
在appdelegate中代理这两个方法
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken{
//尽量收敛到GTNotification中实现
//注册成功
}
- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {
//注册失败
}
剩下的将要弹出跟已经弹出推送的方法，跟本地推送一样
