ios - '初始化(contentsOfURL :)' is unavailable: APIs deprecated as of iOS 7 and earlier are unavailable in Swift

Question

我找不到 contentsOfURL 的任何替代方法来解决此问题。

这是我的 Swift 代码:

import Foundation
import MapKit

class MapHelper{


func geoCodeUsingAddress(address:String) ->CLLocationCoordinate2D{
    var latitude = 0.0
    var longitude = 0.0
    let esc_addr = address.stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding)
    let req = "http://maps.google.com/maps/api/geocode/json?sensor=false&address=\(esc_addr)"

    let result:NSString? = NSString(contentsOfURL: NSURL(string: req)); // here is error //msg comes

    if let value=result{
        let scanner:NSScanner = NSScanner(string: value)
        if(scanner.scanUpToString("\"lat\" :", intoString: nil) && scanner.scanString("\"lat\" :", intoString: nil)){
            scanner.scanDouble(&latitude)
        }
        if(scanner.scanUpToString("\"lng\" :", intoString: nil) && scanner.scanString("\"lng\" :", intoString: nil)){
            scanner.scanDouble(&longitude);
        }
    }
    else{

    }

    var center:CLLocationCoordinate2D = CLLocationCoordinate2D(latitude: 0, longitude: 0);
    center.latitude = latitude;
    center.longitude = longitude;
    return center;

}
}

Answer 1

试试这个

let urlPath: String = "YOUR URL HERE"
let data = NSString(contentsOfURL: urlPath, encoding: NSASCIIStringEncoding, error: nil)
