本地通知 - 重复间隔/自定义时间不起作用

【中文标题】本地通知 - 重复间隔/自定义时间不起作用

【英文标题】：Local Notifications - Repeat Interval / custom time doesn't work

【问题描述】：

似乎无法让一些基本通知正常工作。

我正在使用本地通知向用户发出警报声。

我可以每小时收到一次上班通知。

我似乎无法让一个人每半小时（每 30 分钟，或每 30 分钟或 1 小时）或每 15 分钟工作一次。

如何为每小时重复间隔设置偏移量？通知没有触发。

如果这是不可能的，我将如何手动编写一个循环，直到 64 个排队通知的限制？

【参考方案1】：

好吧，我又试了一次，但它确实可以工作，但资产没有正确导入。我刚刚删除了 finder 中的声音文件并重新导入它们，应用程序正在正确触发通知！
