注释:move(to:)方法将当前绘图位置移动到指定的点,而不绘制路径。 第三步:添加曲线 这一步是实现曲线绘制的核心,使用addCurveToPoint方法来添加曲线。 // 添加曲线bezierPath.addCurve(to:CGPoint(x:250,y:300),// 曲线的结束点controlPoint1:CGPoint(x:100,y:0),// 第一个控

CGContextAddCurveToPoint 的深入理解 CGContextAddCurveToPoint 这个函数看上去一般般,仔细琢磨发现不简单,为什么三个点就可以确定一条曲线呢? 网上查了查,小小研究了一下下。 1.关键知识 窃取自 (http://learn.gxtc.edu.cn/NCourse/jxcamcad/cadcam/Mains/main4-2.htm)...
