Type Property

null

The null rectangle, representing an invalid value.

Declaration

static let null: CGRect

Discussion

This is the rectangle returned when, for example, you intersect two disjoint rectangles. Note that the null rectangle is not the same as the zero rectangle. For example, the union of a rectangle with the null rectangle is the original rectangle (that is, the null rectangle contributes nothing).
