# MKMapViewDefaultAnnotationViewReuseIdentifier

The default reuse identifier for your map’s annotation views.

## Declaration

```swift
let MKMapViewDefaultAnnotationViewReuseIdentifier: String
```

## Discussion

Discussion Use this constant to register a default annotation view. This map view uses this default annotation view when your map view’s delegate doesn’t implement the mapView(_:viewFor:) method, or when that method returns nil.
