Dashed line border around UIView

Question

How do I add dashed line border around UIView.

Something Like this

Answer 1

Use CGContextSetLineDash() method.

CGFloat dashPattern[]= {3.0, 2};

context =UIGraphicsGetCurrentContext();
CGContextSetRGBStrokeColor(context, 1.0, 1.0, 1.0, 1.0);
// And draw with a blue fill color
CGContextSetRGBFillColor(context, 0.0, 0.0, 1.0, 1.0);
// Draw them with a 2.0 stroke width so they are a bit more visible.
CGContextSetLineWidth(context, 4.0);
CGContextSetLineDash(context, 0.0, dashPattern, 2);

CGContextAddRect(context, self.bounds);

// Close the path
CGContextClosePath(context);

CGContextStrokePath(context);

// Fill & stroke the path
CGContextDrawPath(context, kCGPathFillStroke);

I think it will be helpful to you.
