我想在自己的Swift应用程序中打开Apple Maps应用程序,但我只有邮政编码、城市和街道信息,没有坐标信息。我做了很多研究,但只找到了使用坐标信息的方法。

http://maps.google.com/maps?q=1600+Pennsylvania+Ave+NW,+Washington,+DC+20500
UIApplication.sharedApplication().openURL(NSURL(string: "http://maps.apple.com/?address=1600,PennsylvaniaAve.,20500")!)
let geocoder = CLGeocoder()
let str = "1600 Pennsylvania Ave. 20500" // A string of the address info you already have
geocoder.geocodeAddressString(str) { (placemarksOptional, error) -> Void in
if let placemarks = placemarksOptional {
print("placemark| \(placemarks.first)")
if let location = placemarks.first?.location {
let query = "?ll=\(location.coordinate.latitude),\(location.coordinate.longitude)"
let path = "http://maps.apple.com/" + query
if let url = NSURL(string: path) {
UIApplication.sharedApplication().openURL(url)
} else {
// Could not construct url. Handle error.
}
} else {
// Could not get a location from the geocode request. Handle error.
}
} else {
// Didn't get any placemarks. Handle error.
}
}
使用此版本获取地址的坐标,也有一种直接使用地址打开它的方法,但容易出错。
import CoreLocation
let myAddress = "One,Apple+Park+Way,Cupertino,CA,95014,USA"
let geoCoder = CLGeocoder()
geoCoder.geocodeAddressString(myAddress) { (placemarks, error) in
guard let placemarks = placemarks?.first else { return }
let location = placemarks.location?.coordinate ?? CLLocationCoordinate2D()
guard let url = URL(string:"http://maps.apple.com/?daddr=\(location.latitude),\(location.longitude)") else { return }
UIApplication.shared.open(url)
}
苹果有一个有关地图URL方案的文档。请查看这里:https://developer.apple.com/library/archive/featuredarticles/iPhoneURLScheme_Reference/MapLinks/MapLinks.html#//apple_ref/doc/uid/TP40007899-CH5-SW1
Swift 5:直接打开地图应用程序
///Opens text address in maps
static func openAddressInMap(address: String?){
guard let address = address else {return}
let geoCoder = CLGeocoder()
geoCoder.geocodeAddressString(address) { (placemarks, error) in
guard let placemarks = placemarks?.first else {
return
}
let location = placemarks.location?.coordinate
if let lat = location?.latitude, let lon = location?.longitude{
let destination = MKMapItem(placemark: MKPlacemark(coordinate: CLLocationCoordinate2D(latitude: lat, longitude: lon)))
destination.name = address
MKMapItem.openMaps(
with: [destination]
)
}
}
}
import CoreLocation
然后:
let geocoder = CLGeocoder()
let locationString = "London"
geocoder.geocodeAddressString(locationString) { (placemarks, error) in
if let error = error {
print(error.localizedDescription)
} else {
if let location = placemarks?.first?.location {
let query = "?ll=\(location.coordinate.latitude),\(location.coordinate.longitude)"
let urlString = "http://maps.apple.com/".appending(query)
if let url = URL(string: urlString) {
UIApplication.shared.open(url, options: [:], completionHandler: nil)
}
}
}
}
