Question

我有一个我想要更新的地址列表，还添加了lat long。在将地址列表读入数组后，我在CLGeocoder中调用了geocodeAddressString函数。

在完成处理程序中，我如何知道地址列表中的哪个索引用于进行geocodeAddressString调用？

基本上我想设置

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

如何返回位置数组以及如何知道索引，在此示例中= 1？

我希望能够遍历整个阵列。

    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

我假设你的位置是一个班级：

查看您的数组，然后使用此位置：

for location in locations { 

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

PS：如果location是一个结构，那么你需要做一个不同的策略

Answer 2

尝试创建函数并将每个位置发送为inout参数

示例：

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

    }
})
}
