我的问题非常简单。我想在通过按钮按下后,在viewDidLoad
中被调用后,通过调用startSearchingForSessions
,如果iBeacon监测失败,显示错误消息,即“无法找到iBeacon”。
override func viewDidLoad() {
super.viewDidLoad()
self.locationManager = CLLocationManager()
if self.locationManager.responds(to: #selector(CLLocationManager.requestWhenInUseAuthorization)) {
self.locationManager.requestWhenInUseAuthorization()
}
self.locationManager.delegate = self
self.locationManager.pausesLocationUpdatesAutomatically = false
let uuid = UUID(uuidString: "869A6E2E-AE14-4CF5-8313-8D6976058A7A")
self.beaconRegion = CLBeaconRegion(proximityUUID: uuid!, identifier: "com.dejordan.myapp"
startSearchingForSessions()
}
func startSearchingForSessions() {
// Start looking for the beacons with that UUID and Identifier.
self.locationManager.startMonitoring(for: self.beaconRegion)
self.locationManager.startRangingBeacons(in: self.beaconRegion)
self.locationManager.startUpdatingLocation()
}
如此处理发现的信标:
// Required by the Location Manager.
func locationManager(_ manager: CLLocationManager, didEnterRegion region: CLRegion) {
self.locationManager.startRangingBeacons(in: self.beaconRegion)
}
func locationManager(_ manager: CLLocationManager, didDetermineState state: CLRegionState, for region: CLRegion) {
if state == CLRegionState.outside {
print("Cannot Find Beacon")
}
}
// Required by the Location Manager.
func locationManager(_ manager: CLLocationManager, didExitRegion region: CLRegion) {
self.locationManager.stopRangingBeacons(in: self.beaconRegion)
}
// This is called if any beacons are found.
func locationManager(_ manager: CLLocationManager, didRangeBeacons beacons: [CLBeacon], in region: CLBeaconRegion) {
var result = Array<CLBeacon>()
for beacon in beacons {
result.append(beacon)
}
foundBeacons = result
// If we found any, we need to see
// what class they belong to based on information
// from Parse.
self.identifyFoundBeacons()
// We can stop looking for beacons now.
self.locationManager.stopMonitoring(for: self.beaconRegion)
self.locationManager.stopRangingBeacons(in: self.beaconRegion)
self.locationManager.stopUpdatingLocation()
}
我已经实现了委托错误方法,试图找出发生错误的位置,但是在导航iBeacon的大量文档中,我迄今没有取得任何成果。
func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
print("Location manager failed: \(error.localizedDescription)")
}
func locationManager(_ manager: CLLocationManager, monitoringDidFailFor region: CLRegion?, withError error: Error) {
print("Failed monitoring region: \(error.localizedDescription)")
}
谢谢!
