如何在iOS上从照相馆拍摄图像的地方（不是GPS坐标）？

Question

Images in Photos app on iOS sometimes have associated place where photo was taken. Eg, city name or even particular place in the city like Pike Place Market in Seattle. This place is displayed as image title in nav bar in iOS Photos app.

How can I get that metadata?

I'm accessing photos using PHAssetCollection.FetchAssetCollections method.

You can get location directly from PHAsset Object. To get place Info. ie Address use 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)")
        }   
    }
}

Update:

For the address you can get address directly from CLPlacemark Object

See the reference : https://developer.apple.com/documentation/corelocation/clplacemark

from previous code let firstPlacemark = placemarks.first

firstPlacemark.property (property mention below)

// 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
