我很困惑......我今天有这个工作，现在我不知道发生了什么。它不是我的iBeacon，因为我可以使用Locate iOS应用找到它。我正在创建自己的位置管理器，不确定你是否会将其称为子类，因为我是NASSbject的子类。这是：

在我的ViewController中，我以一种非常直接的方式使用它（在顶部：委托方法......对于问题有点无关紧要，在底部：实例化）：
import UIKit
import SceneKit
import ARKit
import CoreLocation
class ViewController: UIViewController, ARSCNViewDelegate, LocationManagerDelegate {
func locationManagerDidUpdateLocation(_ locationManager: LocationManager, location: CLLocation) {
}
func locationManagerDidUpdateHeading(_ locationManager: LocationManager, heading: CLHeading, accuracy: CLLocationDirection) {
}
func locationManagerDidEnterRegion(_ locationManager: LocationManager, didEnterRegion region: CLRegion) {
}
func locationManagerDidExitRegion(_ locationManager: LocationManager, didExitRegion region: CLRegion) {
}
func locationManagerDidDetermineState(_ locationManager: LocationManager, didDetermineState state: CLRegionState, region: CLRegion) {
}
func locationManagerDidRangeBeacons(_ locationManager: LocationManager, beacons: [CLBeacon], region: CLBeaconRegion) {
print("\(beacons) + beacons for ranging")
if beacons.count > 0 {
let nearestBeacon = beacons.first!
let major = CLBeaconMajorValue(truncating: nearestBeacon.major)
let minor = CLBeaconMinorValue(truncating: nearestBeacon.minor)
print("major: \(major)")
print("minor: \(minor)")
print("accuracy: \(nearestBeacon.accuracy)")
switch nearestBeacon.proximity {
case .immediate:
print("--- immediate ---")
case .near:
print("--- near ---")
case .far:
print("--- far ---")
case .unknown:
print("--- proximity unknown ---")
}
}
}
var sceneView: ARSCNView!
var locationManager: LocationManager!
override func viewDidLoad() {
super.viewDidLoad()
sceneView = ARSCNView()
locationManager = LocationManager()
locationManager.delegate = self
...
我的控制台输出是：
2018-02-24 20:40:30.927542-0500 onebeacon[1275:423523] [DYMTLInitPlatform] platform initialization successful

Optional(Set([CLBeaconRegion (identifier:'iBeacon', uuid:12345678-B644-4520-8F0C-720EAF059935, major:1, minor:2)])) + monitoredRegions
所有的iBeacon详细信息都是正确的，因为它一直插入并且未被访问，所以它们今天无法改变。问题总结如下：它似乎将区域添加到＆＃34;要监控的区域＆＃34;列表，但监视似乎永远不会开始，因为我没有中继iBeacon信息的控制台消息。
更新
我会留下我提供的答案，因为它可能是它的一部分（也许不是）......但现在它似乎开始了两次：

正如您所看到monitorBeacons()...行发生两次，我检查确保没有其他的LocationManager实例化，并且没有。
更新
我把它缩小了...问题似乎是didDetermineState函数最初没有触发，我必须从灯塔走出范围（或接近它）然后走路返回并且didDetermineState方法触发，有人知道为什么当我在信标的半径开始时它不会被触发吗？
更新
看来我的手机正在识别它位于某个区域，因为当我走出该区域时，didExitRegion方法会触发，然后didDetermineState方法......奇怪，因为状态应该已经确定didExitRegion方法是否正在触发：

什么是预提交处理程序警告？这些相关吗？
答案 0 :(得分：0)
我的didDetermineState功能在应用初始加载时停止工作。如果我走出信标的范围，然后回到范围内 - didDetermineState方法会触发（以及enter/exit区域方法）。我购买了另一个iBeacon ......它运行良好...而且，奇怪的是，当我同时使用两个信标时，didDetermineState在初始加载时都会检测到两个信标。我不确定为什么didDetermineState停止为一个灯塔工作......当被孤立地使用时。
