An array of numbers specifying the dash pattern to use for the path.
- iOS 7.0+
- macOS 10.9+
- tvOS 9.2+
The array contains one or more
NSNumber objects that indicate the lengths (measured in points) of the line segments and gaps in the pattern. The values in the array alternate, starting with the first line segment length, followed by the first gap length, followed by the second line segment length, and so on.
This property is set to
nil by default, which indicates no line dash pattern.
