I was playing around with drawing paths, and I noticed that in at least some cases, UIBezierPath outperforms what I thought would be a Core Graphics equivalent. The -drawRect: method below creates two paths: one UIBezierPath, and one CGPath. The paths are identical except for their locations, but stroking the CGPath takes roughly twice as long as stroking the UIBezierPath. - (void)drawRect:(CGRect)rect { CGContextRef ctx = UIGraphicsGetCurrentContext(); // Create the two paths, cgpath and uipath. CGMutablePathRef cgpath = CGPathCreateMutable(); CGPathMoveToPoint(cgpath, NULL, 0, 100); UIBezierPath *uipath = [[UIBezierPath alloc] init]; [uipath moveToPoint:CGPointMake(0, 200)]; // Add 200 curve segments to each path. int iterations = 200; CGFloat cgBaseline = 100; CGFloat uiBaseline = 200; CGFloat xincrement = self.bounds.size.width / iterations; for (CGFloat x1 = 0, x2 = xincrement; x2 < self.bounds.size.width; x1
