如何使用Xcode 6（Swift）添加引脚（注释）

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...

我是快速语言的新手，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。让我澄清一下，我甚至不知道从哪里开始，我现在所拥有的（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！！我拥有的...

var MyPins: MKPinAnnotatoinView!

override func viewDidLoad() {
    super.viewDidLoad()

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

你的pin变量是正确的。现在您只需要将此注释添加到MKMapView。

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

您还可以为MKAnnotation创建自定义类，以将自定义注释添加到地图视图。

Follow steps below:

按照以下步骤：

1. Add MapKit.framework to project.

1.将MapKit.framework添加到项目中。

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:

2.创建Storyboard变量IBOutlet的地图视图控件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：

Add delegate signature to view controller interface:

添加委托签名到视图控制器界面：

class ViewController: UIViewController, MKMapViewDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()

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

3. Override its delegate methods:

3.覆盖其委托方法：

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

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

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. Add MKPointAnnotation to map view.

4.将MKPointAnnotation添加到地图视图。

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

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

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)
}

You will need to call a method for when and where the user needs to add the pin. If you want it to add a pin where the user taps and holds on the map, you will need to call a gestureRecognizer, but if you want to do it via a button you will obviously just call that in an action. Either way the documentation for adding pins is throughly discussed Here

您需要为用户需要添加引脚的时间和位置调用方法。如果你想让它添加一个用户点击并保持在地图上的引脚，你需要调用一个gestureRecognizer，但是如果你想通过一个按钮来做，你显然只是在一个动作中调用它。无论哪种方式，添加引脚的文档都在这里进行了详细讨论
