スワイプで複数の注釈の配列を設定する方法

Question

以下の配列をどのように設定する必要がありますか。私のマップに複数の注釈を追加しようとしています。私はstackoverflow上のコードを見つけることができたが、彼らは配列を設定する方法を示していませんでした。

var objects = [ 
       //how should the array be setup here 
       ] 

for objecters in objects!{ 
    if let latit = objecters["Coordinates"]["Latitude"]{ 
     self.latitudepoint = latit as! String 
     self.map.reloadInputViews() 
    } 
    else { 
     continue 
    } 
    if let longi = objecters["Coordinates"]["Longitude"]{ 
     self.longitudepoint = longi as! String 
     self.map.reloadInputViews() 
    } 
    else { 
     continue 
    } 
    var annotation = MKPointAnnotation() 
    var coord = CLLocationCoordinate2D(latitude: Double(self.latitudepoint)!,longitude: Double(self.longitudepoint)!) 
    mapView.addAnnotation(annotation) 
} 

は、例えば

あなたができる：代わり

let locations = [ 
    ["title": "New York, NY", "latitude": 40.713054, "longitude": -74.007228], 
    ["title": "Los Angeles, CA", "latitude": 34.052238, "longitude": -118.243344], 
    ["title": "Chicago, IL",  "latitude": 41.883229, "longitude": -87.632398] 
] 

for location in locations { 
    let annotation = MKPointAnnotation() 
    annotation.title = location["title"] as? String 
    annotation.coordinate = CLLocationCoordinate2D(latitude: location["latitude"] as! Double, longitude: location["longitude"] as! Double) 
    mapView.addAnnotation(annotation) 
} 

または、使用するカスタムタイプ、例えば：

struct Location { 
    let title: String 
    let latitude: Double 
    let longitude: Double 
} 

let locations = [ 
    Location(title: "New York, NY", latitude: 40.713054, longitude: -74.007228), 
    Location(title: "Los Angeles, CA", latitude: 34.052238, longitude: -118.243344), 
    Location(title: "Chicago, IL",  latitude: 41.883229, longitude: -87.632398) 
] 

for location in locations { 
    let annotation = MKPointAnnotation() 
    annotation.title = location.title 
    annotation.coordinate = CLLocationCoordinate2D(latitude: location.latitude, longitude: location.longitude) 
    mapView.addAnnotation(annotation) 
} 

それともあなたは置き換えることができるmapとforループ：

let annotations = locations.map { location -> MKAnnotation in 
    let annotation = MKPointAnnotation() 
    annotation.title = location.title 
    annotation.coordinate = CLLocationCoordinate2D(latitude: location.latitude, longitude: location.longitude) 
    return annotation 
} 
mapView.addAnnotations(annotations)
