I have a strange question. Even though I did read a lot of tutorials on how to do this, the final result only shows the bezier line, not any shadow whatsoever. My code is pretty simple :
let borderLine = UIBezierPath()
borderLine.moveToPoint(CGPoint(x:0, y: y! - 1))
borderLine.addLineToPoint(CGPoint(x: x!, y: y! - 1))
borderLine.lineWidth = 2
UIColor.blackColor().setStroke()
borderLine.stroke()
let shadowLayer = CAShapeLayer()
shadowLayer.shadowOpacity = 1
shadowLayer.shadowOffset = CGSize(width: 0,height: 1)
shadowLayer.shadowColor = UIColor.redColor().CGColor
shadowLayer.shadowRadius = 1
shadowLayer.masksToBounds = false
shadowLayer.shadowPath = borderLine.CGPath
self.layer.addSublayer(shadowLayer)
What am I doing wrong as I dont seem to see anything wrong but of course I am wrong since no shadow appears. The function is drawRect, basic UIVIew no extra anything in there, x and y are the width and height of the frame.
Many thanks in advance!
I take this example straight from my PaintCode-app. Hope this helps.
//// General Declarations
let context = UIGraphicsGetCurrentContext()
//// Shadow Declarations
let shadow = UIColor.blackColor()
let shadowOffset = CGSizeMake(3.1, 3.1)
let shadowBlurRadius: CGFloat = 5
//// Bezier 2 Drawing
var bezier2Path = UIBezierPath()
bezier2Path.moveToPoint(CGPointMake(30.5, 90.5))
bezier2Path.addLineToPoint(CGPointMake(115.5, 90.5))
CGContextSaveGState(context)
CGContextSetShadowWithColor(context, shadowOffset, shadowBlurRadius, (shadow as UIColor).CGColor)
UIColor.blackColor().setStroke()
bezier2Path.lineWidth = 1
bezier2Path.stroke()
CGContextRestoreGState(context)
