ios - CLGeocoder CompletionHandler

Question

所以我试图让它在完成处理程序之后做一些事情，但我一直收到错误:

expected CLGeocodeCompletionHandler

class func didCompleteGeocoding(placemarks: [CLPlacemark]?, error: NSError?, completion: (results: Bool) -> Void){
   if error == nil && placemarks!.count > 0 {
        let placemark = placemarks![0] as! CLPlacemark
        let geocodedLocation = placemark.location!

   //some more code here
   }
   var geoCoder = CLGeocoder()
   var placemarks: [CLPlacemark]?

   func getlocation(){
   let cordinates = geoCoder.geocodeAddressString(locationtext, completionHandler: toSearchandPost2.didCompleteGeocoding(placemarks, error: nil, completion: { (results) -> Void in
           if results == true{
             // do something here
           }
    }))
}

您不能直接使用该功能。请看下面的代码:

func getAndDisplayLocationStringForLocation(currentLocation: CLLocation) {
    CLGeocoder().reverseGeocodeLocation(currentLocation, completionHandler: { (placemarks: [AnyObject]!, error: NSError!) in
        if error == nil && placemarks.count > 0 {
            let location = placemarks[0] as CLPlacemark
            self.textField.text = "\(location.locality) \(location.thoroughfare) \(location.subThoroughfare)"

        }
    })
}

你需要这样调用它:

yourModel.getAndDisplayLocationStringForLocation(someLocation) { (string: String?, error: NSError?) -> () in
    if (error == nil) {
        self.textField.text = string
    }
}

请访问以下链接以获得完整答案。但是，上面的代码就足够了。
