ios - 如何在 iOS 上获取照片库中的图像拍摄位置(不是 GPS 坐标)？

Question

iOS 上的“照片”应用中的图像有时与拍摄照片的地点相关联。例如，城市名称，甚至是城市中的特定地点，例如西雅图的派克市场。此地点在 iOS 照片应用程序的导航栏中显示为图像标题。

如何获取该元数据？

我正在使用 PHAssetCollection.FetchAssetCollections 方法访问照片。

您可以直接从 PHAsset 对象获取位置。获取地点信息。即地址使用 CoreLocation Framework

func reverseGeoCoding(asset: PHAsset) {
    let location = asset.location

    let geocoder = CLGeocoder()
    geocoder.reverseGeocodeLocation(location) { (placemarks, error) in

        if let error = error {
            print("Geo Coding Error: \(error.localizedDescription)")
            return
        }

        guard let placemarks = placemarks,
            let firstPlacemark = placemarks.first,
            let addressDictionary = firstPlacemark.addressDictionary else { return }
        //            let street = addressDictionary["Street"]
        //            let city = addressDictionary["City"]
        //            let state = addressDictionary["State"]
        //            let zip = addressDictionary["ZIP"]
        print(addressDictionary.description)
        if let array = addressDictionary["FormattedAddressLines"] as? [Any] {
            let address = array.map { "\($0)" }.joined(separator: ",\n")
            print("Address : \(address)")
        }   
    }
}

更新:

地址可以直接从CLPlacemark对象中获取地址

参见引用资料:https://developer.apple.com/documentation/corelocation/clplacemark

从前面的代码let firstPlacemark = placemarks.first

firstPlacemark.property(下面提到的属性)

// CLPlacemark properties

open var name: String? { get } // eg. Apple Inc.

open var thoroughfare: String? { get } // street name, eg. Infinite Loop

open var subThoroughfare: String? { get } // eg. 1

open var locality: String? { get } // city, eg. Cupertino

open var subLocality: String? { get } // neighborhood, common name, eg. Mission District

open var administrativeArea: String? { get } // state, eg. CA

open var subAdministrativeArea: String? { get } // county, eg. Santa Clara

open var postalCode: String? { get } // zip code, eg. 95014

open var isoCountryCode: String? { get } // eg. US

open var country: String? { get } // eg. United States

open var inlandWater: String? { get } // eg. Lake Tahoe

open var ocean: String? { get } // eg. Pacific Ocean

open var areasOfInterest: [String]? { get } // eg. Golden Gate Park
