CLGeocoder误差GEOErrorDomain码=-3

Question

当我尝试使用反向地理编码时，出现了这个错误消息。

地理代码错误:错误Domain=GEOErrorDomain代码=-3“(空)”

我的代码如下：

import CoreLocation
geocoder.reverseGeocodeLocation(location) { (placemarks, error) in
    if let placemarks = placemarks {
        reverseGeocodeLocations[hash] = placemarks
    }
    callback(placemarks, error)
}

这只是一次又一次的工作，我每秒钟请求几次reverseGeocode。所以我想这个错误信息是与请求的限制有关还是什么的？有关于苹果公司的地理代码请求的文档吗？谢谢你提前。

这是我请求的全部代码

import CoreLocation

fileprivate struct ReverseGeocodeRequest {

    private static let geocoder = CLGeocoder()
    private static var reverseGeocodeLocations = [Int: [CLPlacemark]]()
    private static let reverseGeocodeQueue = DispatchQueue(label: "ReverseGeocodeRequest.reverseGeocodeQueue")

    private static var nextPriority: UInt = 0

    fileprivate static func request(location: CLLocation, callback: @escaping ([CLPlacemark]?, Error?)->Void) {
        let hash = location.hash
        if let value = reverseGeocodeLocations[hash] {
            callback(value, nil)
        } else {
            reverseGeocodeQueue.async {
                guard let value = reverseGeocodeLocations[hash] else {
                    geocoder.reverseGeocodeLocation(location) { (placemarks, error) in
                        if let placemarks = placemarks {
                            reverseGeocodeLocations[hash] = placemarks
                        }
                        callback(placemarks, error)
                    }
                    return
                }
                callback(value, nil)
            }
        }
    }



    let priority: UInt
    let location: CLLocation
    let handler : ([CLPlacemark]?, Error?)->Void

    private init (location: CLLocation, handler: @escaping ([CLPlacemark]?, Error?)->Void) {
        ReverseGeocodeRequest.nextPriority += 1
        self.priority = ReverseGeocodeRequest.nextPriority
        self.location = location
        self.handler  = handler
    }

}

extension ReverseGeocodeRequest: Comparable {
    static fileprivate func < (lhs: ReverseGeocodeRequest, rhs: ReverseGeocodeRequest) -> Bool {
        return lhs.priority < rhs.priority
    }
    static fileprivate func == (lhs: ReverseGeocodeRequest, rhs: ReverseGeocodeRequest) -> Bool {
        return lhs.priority == rhs.priority
    }

}


extension CLLocation {

    func reverseGeocodeLocation(callback: @escaping ([CLPlacemark]?, Error?)->Void) {
        ReverseGeocodeRequest.request(location: self, callback: callback)
    }

    func getPlaceName(callback: @escaping (Error?, String?)->Void) {
        self.reverseGeocodeLocation { (placemarks, error) in
            guard let placemarks = placemarks, error == nil else {
                callback(error, nil)
                return
            }
            guard let placemark = placemarks.first else {
                callback(nil, "Mysterious place")
                return
            }

            if let areaOfInterest = placemark.areasOfInterest?.first {
                callback(nil, areaOfInterest)
            } else if let locality = placemark.locality {
                callback(nil, locality)
            } else {
                callback(nil, "On the Earth")
            }
        }
    }
}

在到处搜索答案之后，它是在Apples！:/

地理编码请求对每个应用程序都是有限的，因此在短时间内发出太多请求可能会导致某些请求失败。当超过最大速率时，地理编码器将带有值网络的错误对象传递给完成处理程序。

在检查完成处理程序中的错误代码时，确实是网络错误:2

希望这能帮到别人！
