Function

UIRectFrame(_:)

Draws a frame around the inside of the specified rectangle.

Declaration

func UIRectFrame(_ rect: CGRect)

Parameters

rect

The rectangle defining the area in which to draw.

Discussion

This function draws a frame around the inside of rect in the stroke color of the current graphics context and using the kCGBlendModeCopy blend mode. The width is equal to 1.0 in the current coordinate system. Because the frame is drawn inside the rectangle, it is visible even if drawing is clipped to the rectangle. If the current graphics context is nil, this function does nothing.

This function may be called from any thread of your app.
