如何從CLGeocoder geocodeAddressString（）中的完成處理程序更新列表中的地址

Question

我有一個要更新的地址列表，也要添加緯度。 將地址列表讀入數組后，我在CLGeocoder中調用geocodeAddressString函數。

在完成處理程序中，我如何知道使用地址列表中的哪個索引進行geocodeAddressString調用？

基本上我想設置

locations[1].MailAddr1 = placemark.name
locations[1].MailCity = placemark.locality
locations[1].MailState = placemark.administrativeArea
locations[1].MailZip = placemark.postalCode
locations[1].lat = placemark.location!.coordinate.latitude
locations[1].long = placemark.location!.coordinate.longitude

在本示例中，如何返回位置數組以及如何知道索引（該示例為1）？

我希望能夠遍歷整個數組。

    let locations = ReadCSV()

    let address = locations[1].MailAddr1 + ", " + locations[1].MailCity + ", " + locations[1].MailState + ", " +  locations[1].MailZip + ", " + locations[1].MailCountry

    let geocoder = CLGeocoder()
    geocoder.geocodeAddressString(address, completionHandler: {(placemarks, error) -> Void in
        if((error) != nil){
            print("Error", error)
        }
        if let placemark: CLPlacemark = placemarks?.first {
            let name = placemark.name
            let address = placemark.thoroughfare
            let locality = placemark.locality
            let zip = placemark.postalCode
            let subLocality = placemark.subLocality
            let country = placemark.country

            let coordinates:CLLocationCoordinate2D = placemark.location!.coordinate
            let location: CLLocation = placemark.location!


        }
    })

Answer 1

我認為您的位置是一類：

遍歷數組，然后使用此位置：

for location in locations { 

//...
    // in your completion handler
    location.lat = placemark.location!.coordinate.latitude
//...
}

PS：如果位置是一個結構，那么您需要采取其他策略

Answer 2

嘗試使函數並發送每個位置作為inout參數

例：

for location in locations {

 setAddressOflocation(location)

}

func getAddressOflocation (locationObject : inout  CLLocation) {

let address = locationObject.MailAddr1 + ", " + locationObject.MailCity + ", " + locationObject.MailState + ", " +  locationObject.MailZip + ", " + locationObject.MailCountry

let geocoder = CLGeocoder()
geocoder.geocodeAddressString(address, completionHandler: {(placemarks, error) -> Void in
    if((error) != nil){
        print("Error", error)
    }
    if let placemark: CLPlacemark = placemarks?.first {
        let name = placemark.name
        let address = placemark.thoroughfare
        let locality = placemark.locality
        let zip = placemark.postalCode
        let subLocality = placemark.subLocality
        let country = placemark.country

        let coordinates:CLLocationCoordinate2D = placemark.location!.coordinate
        let location: CLLocation = placemark.location!

        locationObject.lat = placemark.location!.coordinate.latitude
        locationObject.long = placemark.location!.coordinate.longitude

    }
})
}
