# invalidatePath()

Updates the path associated with the overlay renderer.

## Declaration

```swift
func invalidatePath()
```

## Discussion

Discussion Call this method when a change in the path information would require you to recreate the overlay’s path. This method sets the path property to nil and tells the overlay renderer to redisplay its contents.
