In this tutorial, you’ll learn how to use Core Graphics to draw lines, rectangles, and gradients — starting by beautifying a table view!
Still damn ugly 
, but a very useful beginner tutorial, thanks for that.
how to make that yellow border to rounded in the masterview controller
Hahaha guess it’s a good job I’m an engineer not a designer :]
Hi @shaktiprakash.
In StarshipListCellBackground, replace the stroke drawing code (after the call to context.drawLinearGradient) with the following:
let strokeRect = backgroundRect.insetBy(dx: 4.5, dy: 4.5)
let path = UIBezierPath(roundedRect: strokeRect, cornerRadius: 5.0)
context.addPath(path.cgPath)
context.setStrokeColor(UIColor.starwarsYellow.cgColor)
context.setLineWidth(1)
context.drawPath(using: .stroke)
Rather than stroking the rect this code creates a UIBezierPath for a rounded rect that fits within the stroke rect with the given corner radius. We then add that path to the context and draw it using context.drawPath(using:) rather than calling the stroke(rect:) convenience function.
@tomelliott thanks man it worked for me .You guys are really doing nice jobs .Thanks for inspiring and motivating us 
Please is anti-aliasing problem happen when we add splitter to each cell in the detail view in that code
class YellowSplitterTableViewCell: UITableViewCell {
override func draw(_ rect: CGRect) {
guard let context = UIGraphicsGetCurrentContext() else {
return
}
let y = bounds.maxY - 0.5
let minX = bounds.minX
let maxX = bounds.maxX
context.setStrokeColor(UIColor.starwarsYellow.cgColor)
context.setLineWidth(1.0)
context.move(to: CGPoint(x: minX, y: y))
context.addLine(to: CGPoint(x: maxX, y: y))
context.strokePath()
}
}
and if not when it happen exactly and how to solve it ?
Hi @gemmen29.
If you were drawing this on a @1x device then that would cause a the line to be anti-aliased. However, on @2x this will still fall on a pixel boundary. On @3x it may be anti-aliased, but in general I wouldn’t worry about that as the pixels are so small you can’t really see!
This tutorial is more than six months old so questions are no longer supported at the moment for it. Thank you!
