ios – Swift中的反向地理编码位置[已关闭]

我的输入是纬度和经度.我需要使用swift的reverseGeocodeLOCATIOn函数,给我本地的输出.我试图使用的代码是

println(geopoint.longitudE) 
            println(geopoint.latitudE)
            var manager : CLLOCATIOnManager!
            var longitude :CLLOCATIOndegrees = geopoint.longitude
            var latitude :CLLOCATIOndegrees = geopoint.latitude

            var LOCATIOn: CLLOCATIOnCoordinate2D = CLLOCATIOnCoordinate2DMake(latitude,longitudE)
            println(LOCATIOn)

            CLGeocoder().reverseGeocodeLOCATIOn(manager.LOCATIOn,completionHandler: {(placemarks,error) -> Void in
                println(manager.LOCATIOn)

                if error != nil {
                    println("Reverse geocoder Failed with error" + error.localizedDescription)
                    return
                }
                if placemarks.count > 0 {
                    let pm = placemarks[0] as CLPlacemark


                    println(pm.locality)
                }


                else {
                    println("Problem with the data received from geocoder")
                }

在我得到的日志中

//-122.0312186
//37.33233141
//C.CLLOCATIOnCoordinate2D
//Fatal error: unexpectedly found nil while unwrapping an Optional value

看来CLLOCATIOnCoordinate2DMake功能失败,这会导致reverseGeocodeLOCATIOn函数中的致命错误.我把这个格式弄糟了吗？

var longitude :CLLOCATIOndegrees = -122.0312186
    var latitude :CLLOCATIOndegrees = 37.33233141

    var LOCATIOn = CLLOCATIOn(latitude: latitude,longitude: longitudE) //changed!!!
    println(LOCATIOn)

    CLGeocoder().reverseGeocodeLOCATIOn(LOCATIOn,error) -> Void in
        println(LOCATIOn)

        if error != nil {
            println("Reverse geocoder Failed with error" + error.localizedDescription)
            return
        }

        if placemarks.count > 0 {
            let pm = placemarks[0] as! CLPlacemark
            println(pm.locality)
        }
        else {
            println("Problem with the data received from geocoder")
        }
    })
