我在地图上有一个标记。滚动地图时,标记也会移动。我可以找到标记的坐标,但是如何使用该坐标查找位置信息?
func locate() {
placesClient.currentPlace(callback: { (placeLikelihoodList, error) -> Void in
if let error = error {
print("Pick Place error: \(error.localizedDescription)")
return
}
let placeInfo = getCurrentPlaceInformation()
self.placeNameLbl.text = placeInfo.name
self.placeAddressLbl.text = placeInfo.address
if let placeLikelihoodList = placeLikelihoodList {
let place = placeLikelihoodList.likelihoods.first?.place
if let place = place {
print("LOG: place name : \(place.name), place Address : \(place.formattedAddress)")
PLACE_NAME = place.name
PLACE_ADDRESS = place.formattedAddress ?? ""
let placeInfo = getCurrentPlaceInformation()
self.placeNameLbl.text = placeInfo.name
self.placeAddressLbl.text = placeInfo.address
}
}
})
}
如何查找自定义坐标以查找地点信息?

Apple反向地理编码API
import CoreLocation
let geocoder = CLGeocoder()
geocoder.reverseGeocodeLocation(<#T##location: CLLocation##CLLocation#>, completionHandler: <#T##CLGeocodeCompletionHandler##CLGeocodeCompletionHandler##([CLPlacemark]?, Error?) -> Void#>)

将GoogleMaps添加到项目中(可以使用Pod)
let geocoder = GMSGeocoder()
geocoder.reverseGeocodeCoordinate(position) { response, error in
//
if error != nil {
print("reverse geodcode fail: \(error!.localizedDescription)")
} else {
if let places = response?.results() {
if let place = places.first {
if let lines = place.lines {
print("GEOCODE: Formatted Address: \(lines)")
}
} else {
print("GEOCODE: nil first in places")
}
} else {
print("GEOCODE: nil in places")
}
}
