如何在场地/企业名称上使用快速地理编码器来获取地址

Question

我正在尝试获取场地/企业名称的地址。对于场地名称，我还提供了城市和州，但成功率不到 10%。问题似乎在于找到位置而不是破译地址。

示例输入：“印第安纳州印第安纳波利斯爵士厨房”

典型输出：“找不到位置”

谢谢！

geocoder.geocodeAddressString(newSearch) { (placemarks, error) in
                    if let error = error {
                        print("Geocoding error: \(error.localizedDescription)")
                        geoError = true
                    }
                    if let placemark = placemarks?.first {
                        if let address = placemark.location?.coordinate {
                            print("Address: \(address)")
                            let webLoc = CLLocation(latitude: address.latitude, longitude: address.longitude)
                            uploadLoc(geoLoc: webLoc)
                        } else {
                            print("No address found")
                            geoError = true
                        }
                    } else {
                        print("No location found")
                        geoError = true
                    }
            }

对于您问题中的示例请求，使用

MKLocalSearch

比

CLGeocoder

效果更好。

以下代码：

import MapKit

let req = MKLocalSearch.Request()
req.naturalLanguageQuery = "Jazz Kitchen Indianapolis,Indiana"
let srch = MKLocalSearch(request: req)
srch.start { resp, error in
    if let resp {
        print(resp.mapItems)
    } else if let error {
        print(error)
    } else {
        print("nothing")
    }
}

给出以下结果：

[<MKMapItem: 0x600002df8d00> {
    isCurrentLocation = 0;
    name = "The Jazz Kitchen";
    phoneNumber = "<redacted for SO>";
    placemark = "The Jazz Kitchen, 5377 N College Ave, Indianapolis, IN 46220, United States @ <+39.85087740,-86.14554230> +/- 0.00m, region CLCircularRegion (identifier:'<+39.85087741,-86.14554230> radius 141.17', center:<+39.85087741,-86.14554230>, radius:141.17m)";
    timeZone = "America/Indiana/Indianapolis (EST) offset -18000";
    url = "http://www.thejazzkitchen.com";
}]
