This depends on a combination of:
- The size of the MapView in use (pixels wide by pixels tall)
- The requested visible region
When this issue occurs, the requested visible region's longitudeDelta is larger than what can be displayed by the map in use. This maximum longitudeDelta will change depending on what section of geography is in the region.
If an author is affected by the issue, there is a potential workaround for their specific content, but the workaround must be tailored to the size of the map in use. There are a couple of ways to determine the workaround's specific maximum value in content:
- Monitor the MapView's "mapViewRegionDidChange" notification to inspect the resulting region when content is visibly affected by this issue. The longitudeDelta value of the map's region has been automatically limited by the view, and this value should be used as a maximum limit for subsequent region changes.
