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

Question

来自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);

有没有一种好方法可以知道这个异步调用何时完成？一旦我知道某个地区的区域监控已启动，我就会尝试执行其他操作，但看起来这可能需要从> 1s到> 20s。

当然是的。在CLLocationManagerDelegate，您会找到- locationManager:didStartMonitoringForRegion:。 here您将找到完整的代表说明。
