如何使用MapKit从坐标获取地址？

当我在地图上长按它获取坐标时,我有这个代码:

func didLongPressMap(sender: UILongPressGestureRecognizer) {

    if sender.state == UIGestureRecognizerState.Began {
        let touchPoint = sender.locationInView(self.mapView)
        let touchCoordinate = self.mapView.convertPoint(touchPoint, toCoordinateFromView: self.mapView)
        var annotation = MKPointAnnotation()
        annotation.coordinate = touchCoordinate
        annotation.title = "Your position"
        self.mapView.addAnnotation(annotation) //drops the pin
        println("lat:  \(touchCoordinate.latitude)")
        var num = (touchCoordinate.latitude as NSNumber).floatValue
        var formatter = NSNumberFormatter()
        formatter.maximumFractionDigits = 4
        formatter.minimumFractionDigits = 4
        var str = formatter.stringFromNumber(num)
        println("long: \(touchCoordinate.longitude)")
        var num1 = (touchCoordinate.longitude as NSNumber).floatValue
        var formatter1 = NSNumberFormatter()
        formatter1.maximumFractionDigits = 4
        formatter1.minimumFractionDigits = 4
        var str1 = formatter1.stringFromNumber(num1) …

如何在swift 2.0中实现拖放区域？

我构建了一个处理kext文件的应用程序但是,现在,我必须手动输入输入kext的路径.我的问题是:如何通过在区域上执行拖放来获取文件路径？
