Google会在iOS上轻松映射iOS SDK位置ID [英] Google maps iOS SDK place id on tap

问题描述

是否可以在POI（iOS google maps SDK）上点击时获取地点ID。

例如，点击一家餐厅，我想调出一些信息，如评论和开放时间。

查看文档可以看到委托方法 mapView（mapView：GMSMapView !, didTapAtCoordinate coordinate：CLLocationCoordinate2D）但没有提供地点ID。我不确定使用坐标来查找确切的位置id有多准确。

你可以做一个将 Google Places API请求添加到地点ID。您可以使用坐标来执行API请求。

示例API请求网址：

  https：// maps。 googleapis.com/maps/api/place/nearbysearch/json?location=-33.8670522,151.1957362&radius=500&key=API_KEY 
  

在iOS中，您可以通过 NSURLSession 执行API请求：

  func placesAPITest（coordinate：CLLocationCoordinate2D）{
 
 let requestURL =https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=\\ \\（坐标。海拔），\（coordinate.longitude）& radius = 500& key = YOUR_API_KEY
 let request = NSURLRequest（URL：NSURL（string：requestURL）！）
 let session = 
 
 
 
 $ b session.dataTaskWithRequest（request，
 completionHandler：{（data：NSData！，response：NSURLResponse！，error：NSError！）if error = = nil {
 let object = NSJSONSerialization.JSONObjectWithData（data，options：nil，错误：无）为！ NSDictionary 
 println（object）
 
 let results = object [results] as！ 
 println（place [place_id]）
 println（place [opening_hours]）
} 
} 
 $ {b $ b println（Places API error）
} 
 
}）。resume（）
} 
  

您可以从 JSON响应。

Is it possible to get the place id when tapping on a POI (iOS google maps SDK).

For example clicking on a restaurant I would like to bring up some of the information such as reviews and opening times.

Looking at the docs I can see the delegate method mapView(mapView: GMSMapView!, didTapAtCoordinate coordinate: CLLocationCoordinate2D) but nothing that provides the place id. Im not sure how accurate it would be to try and find the exact place id using just the coordinates.

解决方案

You can do a Google Places API request to the place ID. You can do the API request by using a coordinate.

Sample API request URL:

https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=-33.8670522,151.1957362&radius=500&key=API_KEY

In iOS, you can do an API request by NSURLSession:

   func placesAPITest(coordinate: CLLocationCoordinate2D) {

        let requestURL = "https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=\(coordinate.latitude),\(coordinate.longitude)&radius=500&key=YOUR_API_KEY"
        let request = NSURLRequest(URL: NSURL(string:requestURL)!)
        let session = NSURLSession.sharedSession()
        session.dataTaskWithRequest(request,
            completionHandler: {(data: NSData!, response: NSURLResponse!, error: NSError!) in

                if error == nil {
                    let object = NSJSONSerialization.JSONObjectWithData(data, options: nil, error: nil) as! NSDictionary
                    println(object)

                    let results = object["results"] as! [NSDictionary]
                    for place in results {
                        println(place["place_id"])
                        println(place["opening_hours"])
                    }
                }
                else {
                    println("Places API error")
                }

        }).resume()
    }

You can get a place ID from the JSON response.
