我试图找出将字符串值传递给Apple地图的最佳方法,以便我可以搜索它。我正在使用类中的应用程序从数组中提取随机字符串,我希望能够调用设备上已有的苹果映射并搜索所选的任何字符串。我已经查找了MKLocalSearchRequest,我认为这可能是最简单的选择,我不知道如何将它与Apple Maps集成,而不是在应用程序内部使用mapkitview。这是我发现的一种方法,似乎它可以工作我只是不确定如何声明它。

 class func openMaps(with mapItems: [MKMapItem], 
 launchOptions: [String : Any]? = nil) -> Bool

import CoreLocation

然后在viewDidLoad

    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)
                }
            }
        }
    }

您可以选择多种方式:

import MapKit
  

第一

UIApplication.shared.openURL(NSURL(string:
    "comgooglemaps://?saddr=&daddr=\(place.latitude),\(place.longitude)&directionsmode=driving")! as URL)
  

或者

@IBAction func action(_ sender: Any) {
    let latitude: CLLocationDegrees = 37.2
    let longitude: CLLocationDegrees = 22.9

    let regionDistance:CLLocationDistance = 10000
    let coordinates = CLLocationCoordinate2DMake(latitude, longitude)
    let regionSpan = MKCoordinateRegionMakeWithDistance(coordinates, regionDistance, regionDistance)
    let options = [
        MKLaunchOptionsMapCenterKey: NSValue(mkCoordinate: regionSpan.center),
        MKLaunchOptionsMapSpanKey: NSValue(mkCoordinateSpan: regionSpan.span)
    ]
    let placemark = MKPlacemark(coordinate: coordinates, addressDictionary: nil)
    let mapItem = MKMapItem(placemark: placemark)
    mapItem.name = "Place Name"
    mapItem.openInMaps(launchOptions: options)
    }

使用此:

UIApplication.shared.open(URL(string:"http://maps.apple.com/?address=yourAddress")!)
