iOS 15 的“时效性通知”有强制力吗？

不会管。用户可以选择关闭通知，删除 app 。

开发和要自觉。
国内这个环境… 用户还是直接关了通知吧…

@linhongye 同意，全部都关闭的

所以这东西本来就是个聊胜于无的功能

除了微信、短信、邮件的通知，其余的全关了，极度清净，其他的真没必要开。

这样一来，国内这些开发商只会把所有推送都设置为时效性推送。

@Tink 如果能高优先级通知提示，其他不提示，那很有用。比如我不想让美团广告推送弹出但是想接收外卖的推送。

@mcluyu 希望 App Store 审核能直接让这种 app 滚出克

那么问题来了，没有对 iOS15 做适配的 app，是否默认是时效性通知？

@EscYezi 都是非时效性通知

@mcluyu 应该不会。时效性通知有醒目的「时效性」标签显示。用户也可以针对每个 app 设置时效性通知也进摘要，不直接推送。开发商没什么必要恶心人，真有那么恶心的跟以前一样直接禁止通知 - -

倒是比较担心开发商不跟进 iOS 15 的特性不搞时效性通知，像 #7 那种情况，我就只好继续禁止通知

就算 App 把推送调成时效性提醒，应该还是可以在通知设置里取消始终允许的，参考 imessage

完全靠自觉

Build trust by accurately representing the urgency of each notification. People have several ways to adjust how they receive notifications from your app — including turning off all notifications — so it’s essential to be as realistic as possible when assigning an interruption level. You don’t want people to feel that a notification uses a high level of urgency to interrupt them with low-priority information.

Use the Time Sensitive interruption level only for notifications that are relevant in the moment. To help people understand the benefits of letting Time Sensitive notifications break through a Focus or scheduled delivery, make sure the notification is about an event that’s happening now or will happen within an hour. The first time a Time Sensitive notification arrives from your app, the system describes how such a notification works and gives people a way to turn it off if they don’t agree that the information requires their immediate attention. Going forward, the system periodically gives people additional opportunities to evaluate how your Time Sensitive notification is working for them. For developer guidance, see UNNotificationInterruptionLevel.

Never use the Time Sensitive interruption level to send a marketing notification. People may have agreed to receive marketing notifications from your app, but such a notification should never break through a Focus or scheduled delivery setting.
