五角大楼画一个小圆圈戴:
- (void)drawPentagon{
//(1)UIBezierPath对象
UIBezierPath *aPath = [UIBezierPath bezierPath];
//開始点
[aPath moveToPoint:CGPointMake(100.0, 1.0)];
//划线点
[aPath addLineToPoint:CGPointMake(200.0, 40.0)];
[aPath addLineToPoint:CGPointMake(160, 140)];
[aPath addLineToPoint:CGPointMake(40.0, 140)];
[aPath addLineToPoint:CGPointMake(0.0, 40.0)];
[aPath closePath];
//设置定点是个5*5的小圆形(自己加的)
UIBezierPath *path = [UIBezierPath bezierPathWithOvalInRect:CGRectMake(100-5/2.0, 0, 5, 5)];
[aPath appendPath:path];
//(2)加到CAShapeLayer,效果出来了
CAShapeLayer *shapelayer = [CAShapeLayer layer];
//设置边框颜色
shapelayer.strokeColor = [[UIColor redColor]CGColor];
//设置填充颜色
shapelayer.fillColor = [[UIColor whiteColor]CGColor];
//就是这句话在关联彼此(UIBezierPath和CAShapeLayer):
shapelayer.path = aPath.CGPath;
[self.view.layer addSublayer:shapelayer];
}
