UIBezierPath的使用方法

UIBezierPath的使用方式：

一，直接添加轨迹，然后stroke或者fill

    UIColor *blue =[UIColor blueColor];

    

    [blue set];

    

    UIBezierPath *bezier =[UIBezierPath bezierPath];

    

    bezier.lineWidth=2;

    bezier.lineCapStyle=kCGLineCapRound;

    bezier.lineJoinStyle=kCGLineJoinRound;

    

    [bezier moveToPoint:CGPointMake(50, 5)];

    

    [bezier addLineToPoint:CGPointMake(90, 25)];

    [bezier addLineToPoint:CGPointMake(75, 50)];

    [bezier addLineToPoint:CGPointMake(25, 50)];

   

    [bezier closePath];

    

    [bezier fill];

 

二，创建UIBezierPath对象，并将去path添加到layer上面

    UIBezierPath *bezier2 =[UIBezierPath bezierPathWithArcCenter:CGPointMake(50, 50) radius:20 startAngle:0 endAngle:M_PI clockwise:YES];

    

    CAShapeLayer *layer =[CAShapeLayer layer];

    layer.path=bezier2.CGPath;

    layer.strokeColor=[UIColor redColor].CGColor;

    layer.fillColor=[UIColor blueColor].CGColor;

    layer.borderWidth=1;

    

    

    [self.layer addSublayer:layer];
