Check UIBezierPath setLineDash:count:phase: method: – (void)setLineDash:(const CGFloat *)pattern count:(NSInteger)count phase:(CGFloat)phase` method. This allows you to draw dashed lines. First add a CAShapeLayer. Add it as sublayer to your UIView. It has a path property. Now make an object of UIBezierPath. Draw the line using setLineDash. For example: UIBezierPath *path = [UIBezierPath bezierPath]; //draw a line … Read more
Solution using Modulo A simple solution that catches all cases. degrees = (degrees + 360) % 360; // +360 for implementations where mod returns negative numbers Explanation Positive: 1 to 180 If you mod any positive number between 1 and 180 by 360, you will get the exact same number you put in. Mod here … Read more
I adapted Apple’s CoreTextArcCocoa sample project (mentioned by Tom H in this reply) and thought I’d share it here. I added a few other features as well, such as the ability to set the arc size to something smaller than 180, and the text color and offset shift as properties (so that you don’t have … Read more
