Rounding the edges of a stroke in bezier path circle in swift

问题

I'm trying to draw a circle using UIBezierPath(ovalInRect: CGRectMake()). Then I'll change the strokeEnd property. When this happens, either end of the circular line have sharp corners. Is there any way to round out these corners?

(I would like to make the beginning and end of this line curved)

回答1:

Assuming you are using a CAShapeLayer to draw this, just set the lineCap, e.g.:

layer.lineCap = .round

回答2:

For drawRect based solutions use lineCapStyle

let path = UIBezierPath(...) path.lineCapStyle = .round
