如果还有其他任何内容可以链接到该问题,请告诉我,以便我可以尝试提供更多详细信息。我约一个星期,我似乎无法找到问题。它可能会让我想要把电脑放在墙上,但我似乎无法弄明白:(
问题似乎已经被隔离到坐标变量,但问题仍然可能与类的构建方式有关,但我无法确定它们是如何形成的。
我可以在发出请求之前将当前位置坐标打印到屏幕,但是在调用将发送api请求的方法时,我在JSON中收到以下错误
“status”:“INVALID_REQUEST”,
Google文档声称:
“INVALID_REQUEST通常表示缺少必需的查询参数(位置或半径)。”
我遇到的是:
使用硬编码坐标,我可以进行搜索并成功返回JSON。
我能够成功获取当前位置坐标。
然而;我无法将当前位置坐标插入到搜索查询中。
这是一大堆代码,我相信只需要掌握这个问题。我感谢任何可能导致解决问题的建议:
// all classes have their own swift file
class ViewController: UIViewController, CLLocationManagerDelegate
{
let currentLocation = CurrentLocation()
let downloadData = DownLoadData()
override func observeValueForKeyPath(keyPath: String?, ofObject object: AnyObject?, change: [String : AnyObject]?, context: UnsafeMutablePointer<Void>)
{
if !didFindMyLocation
{
let myLocation: CLLocation = change![NSKeyValueChangeNewKey] as! CLLocation
currentLocation.coordinate = myLocation.coordinate
currentLocation.latitude = myLocation.coordinate.latitude
currentLocation.longitude = myLocation.coordinate.longitude
didFindMyLocation = true
print(currentLocation.coordinates) // prints coordinates correctly
downLoadData.downloadAllLocations({ () -> () in //request I am attempting to make that outputs,
//"status" : "INVALID_REQUEST",
})
}
}
class CurrentLocation: NSObject, CLLocationManagerDelegate
{
override init()
{
super.init()
}
var locationManager = CLLocationManager()
//THE CULPRITS!
var latitude : CLLocationDegrees!
var longitude : CLLocationDegrees!
}
// typealias in a swift file of its own.
import foundation
typealias DownLoadComplete = () -> ()
class DownloadData: NSObject
{
let currentLocation = CurrentLocation()
override init()
{
super.init()
}
func downloadAllLocations(completed: DownloadComplete)
{
//hardcoded coordinates output correct JSON Response. So Why Cant I Interpolate the coordinates from my current location???
let URL_Search = "https://maps.googleapis.com/maps/api/place/nearbysearch/json?"
let urlString = "\(URL_Search)location=\(currentLocation.latitude),\(currentLocation.longitude)&radius=\(searchRadius)&types=\(searchType)&key=\(API_ServerKey)"
let url = NSURL(string: urlString)!
print(url) // outputs nil,nil in the currentLocation.latitude and currentLocation.longitude spots
Alamofire.request(.GET,url).responseJSON { (response) -> Void in
switch response.result
{
case .Success:
if let value = response.result.value
{
let json = JSON(value)
print(json) // If hardcoded coordinates are inserted then I the json is outputted. If current location is attempted then I receive an INVALID_REQUEST error.
if let results = json["results"].array
{
for result in results {
if let places = result["place"].string
{
self.places = place
}
}
}
}
case .Failure(let error):
print(error)
}
completed()
}
}
}
在发送请求之前通过print(currentLocation.coordinates)测试输出(downLoadData.downLoadAllLocation [其中有一个打印(url)被调用])输出到调试控制台是:
CLLocationCoordinate2D(纬度:37.33233141,经度:-122.0312186) https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=nil,nil ...等
这里的问题是插入到搜索查询中的坐标显示为nil,nil?我试过操纵代码。但是没有运气......看起来很奇怪他们被打印但是在搜索中他们看起来是零。怎么可能??
答案 0 :(得分:0)
DownloadData
类引用currentLocation
变量(可能是CurrentLocation
的一个实例,但是此变量未在代码示例中的任何位置定义。我假设它是一个成员变量ViewController
,在这种情况下,问题是:DownloadData
如何了解它?
您可能需要将currentLocation
传递给downloadData.downloadAllLocations()
作为参数。
