Question

我正在使用Instagram API for iOS。我想按名称搜索位置，就像Instagram应用程序本身一样，但是唯一可用于搜索位置的端点是LAT和LONG。

有没有办法让它像Instagram应用程序本身那样，通过输入名称来搜索位置？

THX！

我做过类似的事情，但我必须自己编写代码。我使用searchBar来获取位置，并将位置固定为annotation到MapView我使用annotation坐标来执行搜索。我故意显示地图和图钉。这是我使用的代码。

         // do search for locations 
         localSearchRequest = MKLocalSearchRequest() 
         localSearchRequest.naturalLanguageQuery = searchBar.text 
         localSearch = MKLocalSearch(request: localSearchRequest) 
         localSearch.start { (localSearchResponse, error) -> Void in 


             // alert if location not found 
             if localSearchResponse == nil{ 
                 let alertController = UIAlertController(title: nil, message: "Place Not Found", preferredStyle: UIAlertControllerStyle.alert) 
                 alertController.addAction(UIAlertAction(title: "Dismiss", style: UIAlertActionStyle.default, handler: nil)) 
                 self.present(alertController, animated: true, completion: nil) 
                 activityIndicator.hide() 
                 return 
             } 

             // append annotation if result is found 
             self.pointAnnotation = MKPointAnnotation() 
             self.pointAnnotation.title = searchBar.text 
             // get pin location 
             self.pointAnnotation.coordinate = CLLocationCoordinate2D(latitude: localSearchResponse!.boundingRegion.center.latitude, longitude:     localSearchResponse!.boundingRegion.center.longitude) 


             self.pinAnnotationView = MKPinAnnotationView(annotation: self.pointAnnotation, reuseIdentifier: nil) 
             self.mapView.centerCoordinate = self.pointAnnotation.coordinate 


             self.mapView.addAnnotation(self.pinAnnotationView.annotation!)

如果您不打算使用mapView，您仍然可以使用此代码获取Lat和Long的位置

let location = CLLocationCoordinate2D(latitude:
                       localSearchResponse!.boundingRegion.center.latitude,
                       longitude: localSearchResponse!.boundingRegion.center.longitude)

在Instagram API中按名称搜索位置
