Question

func locationManager(_ manager: CLLocationManager, didEnterRegion region: CLRegion) {

如何在 didEnterRegion 中获取 UUID？请帮助我..

Answer 1

你只需要CLRegion投射到CLBeaconRegion。 就像 Swift 3 中的这样：

let beaconRegion = region as! CLBeaconRegion

或者在目标C中：

CLBeaconRegion *beaconRegion = (CLBeaconRegion *)region;

完成此操作后，您可以访问CLBeaconRegion上的任何字段：

斯威夫特 3：

NSLog("My UUID: (beaconRegion.proximityUUID)")

目标C：

NSLog(@"My UUID: %@", beaconRegion.proximityUUID);

你可以

试试这个。

func locationManager(manager: CLLocationManager, didEnterRegion region: CLRegion) {
    manager.startRangingBeaconsInRegion((region as! CLBeaconRegion))
    var r = (region as! CLBeaconRegion)
    self.sendLocalNotificationWithMessage("(r.proximityUUID)")
    self.sendLocalNotificationWithMessage("(r.identifier)")
}
