如何使用Xcode 6（Swift）添加引脚（注释） [英] How Do I add Pins (Annotations) with Xcode 6 (Swift)

问题描述

我是swift语言的新手，还没有用mapkit做过应用程序。但是我已经设置了地图和区域，但是我已经挂断了如何允许用户添加引脚。
让我澄清，我甚至不知道从哪里开始，我现在所有的（针脚）是我的变量，但我甚至不确定这是否正确。任何帮助将非常感激！！
我有什么......

I'm new to the swift language, and haven't done an application with mapkit yet. But I have the map and regions set, but I'm hung up on how to allow users to add pins. Let me clarify, I have no idea of even where to start, All I have at the moment (for the pins) is my variable, but I'm not even sure if that's correct. Any help would be much appreciated!! What I have...

var MyPins：MKPinAnnotatoinView！

var MyPins: MKPinAnnotatoinView!

..... 。

override func viewDidLoad() {
    super.viewDidLoad()

Mapview代码

.....
.....
}

..... ..... }

推荐答案

你的pin变量是正确的。现在您只需要将此注释添加到 MKMapView 。

Your pin variable is correct. Now you just need to add this annotation to MKMapView.

您还可以为 MKAnnotation 创建自定义类，以便为地图视图添加自定义注释。

You can also create a custom class for MKAnnotation to add custom annotation to map view.

按照以下步骤操作：

的 1。将 MapKit.framework 添加到项目中。

1. Add MapKit.framework to project.

2。创建地图视图控件的Storyboard变量 IBOutlet 或在视图控制器中创建它。设置此变量的委托以覆盖它的委托方法：

2. Create Storyboard variable IBOutlet of map view control or create it in view controller. Set delegate for this variable to override it's delegate methods:

将委托签名添加到视图控制器界面：

Add delegate signature to view controller interface:

class ViewController: UIViewController, MKMapViewDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()

        // Set map view delegate with controller
        self.mapView.delegate = self
    }
}

3。覆盖其委托方法：

这里我们需要覆盖 mapView（_：viewForAnnotation：）方法在地图上显示注释引脚。

Here we need to override mapView(_:viewForAnnotation:) method to show annotation pins on map.

func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? {
    if (annotation is MKUserLocation) {
        return nil
    }

    if (annotation.isKind(of: CustomAnnotation.self)) {
        let customAnnotation = annotation as? CustomAnnotation
        mapView.translatesAutoresizingMaskIntoConstraints = false
        var annotationView = mapView.dequeueReusableAnnotationView(withIdentifier: "CustomAnnotation") as MKAnnotationView!

        if (annotationView == nil) {
            annotationView = customAnnotation?.annotationView()
        } else {
            annotationView?.annotation = annotation;
        }

        self.addBounceAnimationToView(annotationView)
        return annotationView
    } else {
        return nil
    }
}

4。将 MKPointAnnotation 添加到地图视图。

4. Add MKPointAnnotation to map view.

您可以在地图视图中将pin添加到位置。为简单起见，将代码添加到 viewDidLoad（）方法。

You can add pin to location in map view. For simplicity add code to viewDidLoad() method.

override func viewDidLoad() {
    super.viewDidLoad()

    // Set map view delegate with controller
    self.mapView.delegate = self

    let newYorkLocation = CLLocationCoordinate2DMake(40.730872, -74.003066)
    // Drop a pin
    let dropPin = MKPointAnnotation()
    dropPin.coordinate = newYorkLocation
    dropPin.title = "New York City"
    mapView.addAnnotation(dropPin)
}
