Accessing MKLocalSearchResponse item (swift)

问题

When I do println(localSearchResponse), I get a MapItem object, which includes a ton of details about the location. In this example, its UCSD. Here is the output showing in my log.

<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 = \"+18585342230\";\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}"
    );
}

Notice how it outputs placemark = University of California... and has the address? How do I get this value and store it into a variable? Here is my code:

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
}

Here is the documentation of MKSearchResponse

And here is the documentation of MKMapItem

The answer is:

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

This object contains all information you need. Checked it in demo project

Address only:

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

newRecordAddress.name is place's name newRecordAddress.title is place's address you required

Because mapItems is an array, you need to call first to access the first element of that array. This will return an MKMapItem, so you can get the placemark property with this code:

localSearchResponse.mapItems.first.placemark
