ios - 有什么好方法可以知道 CLLocationManager 的 startMonitoringForRegion 何时完成？

Question

从 CLLocationManager.h:

/*
 *  startMonitoringForRegion:
 *
 *  Discussion:
 *      Start monitoring the specified region.
 *
 *      If a region of the same type with the same identifier is already being monitored for this application,
 *      it will be removed from monitoring. For circular regions, the region monitoring service will prioritize
 *      regions by their size, favoring smaller regions over larger regions.
 *
 *      This is done asynchronously and may not be immediately reflected in monitoredRegions.
 */
- (void)startMonitoringForRegion:(CLRegion *)region __OSX_AVAILABLE_STARTING(__MAC_TBD,__IPHONE_5_0);

有什么好方法可以知道这个异步调用何时完成？一旦我知道某个区域的区域监视已启动，我将尝试执行另一项操作，但看起来这可能需要 >1s 到 >20s 之间的任何时间。

当然是的。在 CLLocationManagerDelegate你会发现- locationManager:didStartMonitoringForRegion: . here您将找到完整的代表说明。
