Accessing MKLocalSearchResponse item (swift)

Question

当我执行println(localSearchResponse)时，我得到一个MapItem对象，其中包含大量关于位置的详细信息。在这个例子中，它是UCSD。以下是我的日志中显示的输出。

<MKLocalSearchResponse: 0x1c53d640> {
    boundingRegion = "<center:+32.87514836, -117.23958822 span:+0.00725621, +0.00825332>";
    mapItems =     (
        "<MKMapItem: 0x1c538090> {n    isCurrentLocation = 0;n    name = "University of California, San Diego";n    phoneNumber = "[phone]";n    placemark = "University of California, San Diego, 9500 Gilman Dr, La Jolla, CA  92093-5004, United States @ <+32.87529400,-117.23961000> +/- 0.00m, region CLCircularRegion (identifier:'<+32.87514837,-117.23958825> radius 557.57', center:<+32.87514837,-117.23958825>, radius:557.57m)";n    url = "http://www.ucsd.edu";n}"
    );
}

注意它是如何输出placemark = University of California...和地址的?我如何获得这个值并将其存储到一个变量中?下面是我的代码:

localSearchRequest = MKLocalSearchRequest()
localSearchRequest.naturalLanguageQuery = addressTextField.text
localSearch = MKLocalSearch(request: localSearchRequest)
localSearch.startWithCompletionHandler { (localSearchResponse, error) -> Void in
    if localSearchResponse == nil{
        var alert = UIAlertView(title: nil, message: "Place not found", delegate: self, cancelButtonTitle: "Try again")
        alert.show()
        return
    }
    //prints the MKLocalSearchResponse with name, phoneNumber, placemark
    println(localSearchResponse)
    //Get latitude and longitude
    var newRecordLat = localSearchResponse.boundingRegion.center.latitude
    var newRecordLong = localSearchResponse.boundingRegion.center.longitude
    //How do I get the address, which is "placemark" in the MKLocalSearchResponse?
    var newRecordAddress = localSearchResponse.mapItems...???
    //store values to Parse
    self.latToParse = newRecordLat
    self.longToParse = newRecordLong
}

Answer 1

答案是:

var newRecordAddress = (localSearchResponse.mapItems[0] as! MKMapItem).placemark

该对象包含您需要的所有信息。在demo项目中检查

只

地址:

var newRecordAddress = (localSearchResponse.mapItems[0] as! MKMapItem).placemark
let addressOnly = newRecordAddress.name + ", " + newRecordAddress.title

newRecordAddress.name为地名newRecordAddress.title是您需要的地址

Answer 2

因为mapItems是一个数组，所以需要调用first来访问该数组的第一个元素。这将返回一个MKMapItem，因此您可以使用以下代码获得placemark属性:

localSearchResponse.mapItems.first.placemark
