//1.创建贝塞尔路径的实例
UIBezierPath*path = [UIBezierPathbezierPath];
//2.勾勒一个图形
//移动画笔
[pathmoveToPoint:CGPointMake(50,50)];
//加一条线到260 260的位置
[pathaddLineToPoint:CGPointMake(250,50)];
[pathaddLineToPoint:CGPointMake(250,150)];
[pathaddLineToPoint:CGPointMake(50,150)];
//[path addLineToPoint:CGPointMake(50, 50)];
//[path closePath];
//[path moveToPoint:CGPointMake(50, 200)];
//[path addLineToPoint:CGPointMake(250, 200)];
//[path addLineToPoint:CGPointMake(250, 350)];
//[path addLineToPoint:CGPointMake(50, 350)];
//[path closePath];
//3.设置描边色填充色
[[UIColorredColor]setStroke];
[[UIColorgreenColor]setFill];
//设置描边的宽度
path.lineWidth=10;
//焦点的样式
/*
kCGLineJoinMiter,
kCGLineJoinRound,
kCGLineJoinBevel
*/
path.lineJoinStyle=kCGLineJoinBevel;
//线两端的样式
/*
kCGLineCapButt,
kCGLineCapRound,
kCGLineCapSquare
*/
path.lineCapStyle=kCGLineCapSquare;
//4.描边及填充
[pathstroke];
//[path fill];
