如何使用swift ios在mapview中添加两个注释？

我已经为一个位置创建了一个注释。现在，我需要为另一个位置再创建一个注释，并在地图中显示它。如何显示它？

将自定义类创建为“MyAnnotation”

在viewcontroller的视图加载中添加以下代码：-

import UIKit
import MapKit

class MyAnnotation: NSObject,MKAnnotation {

    var title : String?
var subTit : String?
var coordinate : CLLocationCoordinate2D

init(title:String,coordinate : CLLocationCoordinate2D,subtitle:String){

    self.title = title;
    self.coordinate = coordinate;
    self.subTit = subtitle;

}

}

相反，您也可以使用for循环

希望这将对您有所帮助。

无需自定义类。只需在位置之间循环，即可为每个位置创建注释。 假设地点为CLLocations，城市名称为cityNames，myMap为地图（UI）

我不明白。你能给我完整的代码吗@呃,沙。由于我是swift的新手，我在理解代码方面遇到了困难。非常感谢@呃,什里扬斯Shah@RakeshMohan：-Accept和+1，如果上面的答案对您有效。我使用了上面提供的相同代码，但它仍然只显示一个注释。亲爱的。。对地图视图进行缩放/移动。在模拟中，使用cmd+altr键缩放/缩放

import UIKit
import MapKit

class MyAnnotation: NSObject,MKAnnotation {

    var title : String?
var subTit : String?
var coordinate : CLLocationCoordinate2D

init(title:String,coordinate : CLLocationCoordinate2D,subtitle:String){

    self.title = title;
    self.coordinate = coordinate;
    self.subTit = subtitle;

}

}

        let latitude:CLLocationDegrees = 76.0100
        let longitude:CLLocationDegrees = 25.3620

        let location:CLLocationCoordinate2D = CLLocationCoordinate2DMake(latitude, longitude)

        //Second Location lat and long
        let latitudeSec:CLLocationDegrees = 75.0100
        let longitudeSec:CLLocationDegrees = 24.3620

        let locationSec:CLLocationCoordinate2D = CLLocationCoordinate2DMake(latitudeSec, longitudeSec)

        let span:MKCoordinateSpan = MKCoordinateSpanMake(1, 1)

        let region:MKCoordinateRegion = MKCoordinateRegionMake(location, span)

        mapView.setRegion(region, animated: true)


        let myAn1 = MyAnnotation(title: "Office", coordinate: location, subtitle: "MyOffice");

        let myAn2 = MyAnnotation(title: "Office 1", coordinate: locationSec, subtitle: "MyOffice 1");

        mapView.addAnnotation(myAn1);
        mapView.addAnnotation(myAn2);
        //Instead of writing two lines of annotation we can use addAnnotations() to add.

var counter = 0
var allLocations = [MKPointAnnotation]()
for location in Locations {
    let loc = MKPointAnnotation()
    loc.title = cityNames[counter]
    loc.subtitle = String(counter + 1)
    loc.coordinate = CLLocationCoordinate2D(latitude: location.coordinate.latitude,
                                            longitude: location.coordinate.longitude);
    allLocations.append(loc)
    counter += 1 
}
// show annotations
myMap.addAnnotations(allLocations as [MKAnnotation])
myMap.showAnnotations(myMap.annotations, animated: true)
