ios - UNNotification 本地通知和请勿打扰

Question

Sleep Cycle 应用程序设法发送本地通知并播放声音，即使我在手机上启用了“请勿打扰”。

你是怎么做到的？

Answer 1

好吧，可以通过在配置本地通知时启用 UNNotificationSetting 中的“严重警报”属性来实现。

Apple 文档 - https://developer.apple.com/documentation/usernotifications/unnotificationsettings/2963116-criticalalertsetting

When UNNotificationSetting.enabled, this property authorizes the app to play critical sounds that ignore Do Not Disturb and the device’s mute switch.

For local notifications, the system attempts to play a critical sound when the sound property of the UNNotificationContent object contains an object returned by the defaultCritical property, the criticalSoundNamed(_:) method, or a related method.

For remote notifications, the system attempts to play a critical sound when the notification’s payload contains a sound directory that contains the critical key.

Critical alerts require a special entitlement issued by Apple.
