使细节按钮在 iOS MapView 中始终可见

Question

I have a map view on my iOS app and i want to make detail button that when user press the pin icon visible without interaction. It should be visible when user open the map. Is it possible to make it? I use the code for showing annotation, I need it for button.

self.mapView.showAnnotations([destinationAnnotation], animated: true )

Answer 1

Yes it is possible to show annotation once you load map. You can simply make annotation is "selected". While this is generally achieved by a user tapping on the annotation view (ie the pin), you can also programmatically "select" the annotation:

mapView.selectAnnotation(annotation, animated: true)

When you add pin.

Answer 2

您可以尝试以编程方式选择 mapView annoattion：

mapView.selectAnnotation(annotation, animated:false)
