xcode – geocoder.geocodeAddressString今天不再适用于swift更

表明有一些变化

func geocodeAddressString(_ addressString: String!,completionHandler completionHandler: CLGeocodeCompletionHandler!)

至：

func geocodeAddressString(_ addressString: String,completionHandler completionHandler: CLGeocodeCompletionHandler)

我的代码是：

var geocoder = CLGeocoder()

geocoder.geocodeAddressString("(event!.street),(event!.city),(event!.country)",completionHandler: {(placemarks: [AnyObject]!,error: NSError!) -> Void in
    if let placemark = placemarks?[0] as? CLPlacemark {
        self.event!.lat = placemark.location!.coordinate.latitude
        self.event!.long = placemark.location!.coordinate.longitude

        self.event!.getMiles(self.currentLocation!.location!.coordinate.latitude,clong: self.currentLocation!.location!.coordinate.longitude)
        var mile = self.event!.miles != nil ? NSString(format: "%.1f miles",self.event!.miles!) : "Location services off"
        self.milesButton.setTitle(mile as String,forState: .Normal)
    }
})

尝试：

var geocoder = CLGeocoder()
let address = "(event!.street),(event!.country)"
geocoder.geocodeAddressString(address,completionHandler: {(placemarks: [CLPlacemark]) in
     let placemark = placemarks[0]
     self.event!.lat = placemark.location!.coordinate.latitude
     self.event!.long = placemark.location!.coordinate.longitude
     self.event!.getMiles(self.currentLocation!.location!.coordinate.latitude,clong: self.currentLocation!.location!.coordinate.longitude)
     var mile = self.event!.miles != nil ? NSString(format: "%.1f miles",self.event!.miles!) : "Location services off"
     self.milesButton.setTitle(mile as String,forState: .Normal)
})

它只是说它不被允许.尝试了几种不同的组合.这是对xcode / swift的最新更新
