ios - 单个应用允许多少个基于区域的 UILocalNotification

Question

苹果 Doc说:

Apps are limited in the total number of regions they may monitor at any given time, and local notifications configured with a region value count against that total.

但是total number没有指定，如何知道应用可以监控的区域总数的限制。

Answer 1

根据 Apple 的 Location and Maps Programming Guide，每个应用程序的数量限制为 20 个:

Be judicious when specifying the set of regions to monitor. Regions are a shared system resource, and the total number of regions available systemwide is limited. For this reason, Core Location limits to 20 the number of regions that may be simultaneously monitored by a single app. To work around this limit, consider registering only those regions in the user’s immediate vicinity.
