ios - 如何将自定义 map 图钉添加到 Apple Watch 上的 map View ？

Question

我开始为 Apple Watch 编写代码，我想知道如何做到这一点:

谢谢!

Answer 1

首先，您需要向 Controller 添加 map View (例如 InterceController.swift )

然后，您可以在 InterfaceController.swift 中调用这些行的awakeWithContext()或willActivate()

 let location = CLLocationCoordinate2D(
            latitude: 51.530777,
            longitude: -0.139364
        )

 let span = MKCoordinateSpan(
            latitudeDelta: 0.005,
            longitudeDelta: 0.005
       )

 let region = MKCoordinateRegion(center: location, span: span)

 map.setRegion(region)

 map.addAnnotation(location, withImageNamed: "bee.png", centerOffset: CGPoint(x: 0, y: 0))

关键是调用addAnnotation(location: CLLocationCoordinate2D, withImageNamed name: String!, centerOffset offset: CGPoint)

等效的 Objective-C 代码:

  CLLocationCoordinate2D location = CLLocationCoordinate2DMake(51.530777, -0.139364);

    MKCoordinateSpan span = MKCoordinateSpanMake(0.005, 0.005);

    MKCoordinateRegion region = MKCoordinateRegionMake(location, span);

    [self.map setRegion:region];

    [self.map addAnnotation:location withImageNamed:@"bee.png" centerOffset:CGPointMake(0, 0)];
