Draw dotted (not dashed!) line, with IBDesignable in 2017

Question

It\'s easy to draw a dashed line with UIKit. So:

CGFloat dashes[] = {4, 2};
[path setLineDash:dashes count:2 phase:0];
[path stroke];
         


        

Answer 1

I have implemented following piece of code to add border with dotted style at bottom of titleLabel (UILabel) in viewDidAppear:

CAShapeLayer *shapelayer = [CAShapeLayer layer];
UIBezierPath *path = [UIBezierPath bezierPath];
[path moveToPoint:CGPointMake(0.0, titileLabel.frame.size.height-2)];
[path addLineToPoint:CGPointMake(SCREEN_WIDTH, titileLabel.frame.size.height-2)];
UIColor *fill = [UIColor colorWithRed:0.80f green:0.80f blue:0.80f alpha:1.00f];
shapelayer.strokeStart = 0.0;
shapelayer.strokeColor = fill.CGColor;
shapelayer.lineWidth = 2.0;
shapelayer.lineJoin = kCALineJoinRound;
shapelayer.lineDashPattern = [NSArray arrayWithObjects:[NSNumber numberWithInt:2],[NSNumber numberWithInt:3 ], nil];
shapelayer.path = path.CGPath;

[titileLabel.layer addSublayer:shapelayer];
