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。这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 = \"+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}"
    );
}

注意它是如何输出 placemark = University of California... 和地址的吗？如何获取此值并将其存储到变量中？这是我的代码：

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
}

这是MKSearchResponse

Answer 1

因为mapItems是一个数组，你需要调用first来访问那个数组的第一个元素。这将 return 一个 MKMapItem，因此您可以使用此代码获取地标属性：

localSearchResponse.mapItems.first.placemark

Answer 2

答案是：

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

此对象包含您需要的所有信息。在演示项目中检查过

仅地址：

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

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