我在我们的产品应用程序的Apple CoreLocation线程中收到此崩溃。我无法在我的测试中重现它，也很难把它看作是它的CoreLocation。目前它发生的人口比例很低，但我可以看到它变得更大。CoreLocation线程崩溃崩溃：com.apple.CoreLocation.ConnectionClient.0x16fcb870.events

我们使用CoreLocation监测&范围具体灯塔地区，这里是寻找附近的灯塔的代码。 另请注意，HPBeaconManager在应用程序到达前台时重新初始化，并从crashlytics报告中发现 它看起来应用程序到达前台时会发生。破坏CLLocationManger对象并重新初始化可以导致这个问题吗？任何正确的方向，将不胜感激。
这里是调用代码。
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
self.beaconManager = HPBeaconManager()
self.beaconManager?.startMonitoring()
return true;
}
func applicationDidBecomeActive(application: UIApplication)
if ((self.beaconManager) != nil){
self.beaconManager = nil;
}
self.beaconManager = HPBeaconManager()
self.beaconManager?.startRanging()
}
这是HPBeaconManager的实现。
class HPBeaconManager: NSObject , CLLocationManagerDelegate {
var propertyBeaconRegion: HPBeaconRegion?
var agentBeaconRegion: HPBeaconRegion?
var locationManager: CLLocationManager = CLLocationManager()
var delegate:BeaconManagerDelegate?
var beacons:NSMutableSet = NSMutableSet()
override init() {
super.init()
self.propertyBeaconRegion = HPBeaconRegion(proximityUUID: HPBeaconCommons.propertyUUID, major: CLBeaconMajorValue(1), identifier: HPBeaconCommons.propertyBeaconIdentifier)
self.agentBeaconRegion = HPBeaconRegion(proximityUUID: HPBeaconCommons.agentUUID, major: CLBeaconMajorValue(1), identifier: HPBeaconCommons.agentBeaconIdentifier)
self.locationManager = CLLocationManager()
self.locationManager.delegate = self
}
func startMonitoring() -> Void {
self.locationManager.startMonitoringForRegion(self.agentBeaconRegion!)
self.locationManager.startMonitoringForRegion(self.propertyBeaconRegion!)
self.locationManager.startRangingBeaconsInRegion(self.agentBeaconRegion!)
self.locationManager.startRangingBeaconsInRegion(self.propertyBeaconRegion!)
strongSelf.locationManager.startUpdatingLocation()
}
func stopMonitoring() -> Void {
self.locationManager.stopMonitoringForRegion(self.agentBeaconRegion!)
self.locationManager.stopMonitoringForRegion(self.propertyBeaconRegion!)
self.locationManager.stopRangingBeaconsInRegion(self.agentBeaconRegion!)
self.locationManager.stopRangingBeaconsInRegion(self.propertyBeaconRegion!)
self.locationManager.stopUpdatingLocation()
}
func startRanging() {
self.locationManager.startRangingBeaconsInRegion(self.agentBeaconRegion!)
self.locationManager.startRangingBeaconsInRegion(self.propertyBeaconRegion!)
}
func locationManager(manager: CLLocationManager, didStartMonitoringForRegion region: CLRegion) {
NSLog("\n ************** Monitoring starts for region %@", region.identifier)
}
func locationManager(manager: CLLocationManager, didDetermineState state: CLRegionState, forRegion region: CLRegion) {
}
func locationManager(manager: CLLocationManager, didEnterRegion region: CLRegion) {
NSLog("\n ************** Did Enter Region")
}
func locationManager(manager: CLLocationManager, didExitRegion region: CLRegion) {
}
func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
var locationArray = locations as NSArray
if locationArray.count > 0 {
var locationObj = locationArray.lastObject as! CLLocation
var coord = locationObj.coordinate
let loationString = "\(coord.latitude)|\(coord.longitude)"
}
}
func locationManager(manager: CLLocationManager!, didRangeBeacons beacons: [AnyObject]!, inRegion region: CLBeaconRegion!) {
if beacons.count > 0 {
let nearestBeacon:CLBeacon = beacons[0] as! CLBeacon
....
}
}
func locationManager(manager: CLLocationManager!, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
if status == .AuthorizedAlways {
NSLog("Location Access (Always) granted!")
dispatch_after(dispatch_time_t(0.5), dispatch_get_main_queue(), { [weak self] in
if let strongSelf = self {
if manager.rangedRegions.isEmpty {
NSLog("Ranged region is empty")
}
strongSelf.startMonitoring()
}
})
} else if status == .AuthorizedWhenInUse {
NSLog("Location Access (When In Use) granted!")
dispatch_after(dispatch_time_t(0.5), dispatch_get_main_queue(), { [weak self] in
if let strongSelf = self {
if manager.rangedRegions.isEmpty {
NSLog("Ranged region is empty")
}
strongSelf.startMonitoring()
}
})
} else if status == .Denied || status == .Restricted {
NSLog("Location Access (When In Use) denied!")
}
}
deinit {
NSLog("BeaconManager cleanup")
self.locationManager.stopUpdatingLocation()
self.locationManager.delegate = nil
}
}
这不会回答你的问题，但我建议你为你的代码采用“Swiftier”语法。无处不在的分号，当你不返回任何内容时，不需要指定“Void”，使用NSLog可以实现简单的打印。 – H4Hugo
编辑..谢谢你的建议..我使用NSLogs，因为当在物理设备上执行时，NSLog语句出现在设备的控制台中，而println只出现在调试器控制台中。 – bytescrafter
