五角大楼画一个小圆圈戴:
- (void)drawPentagon{
//(1)UIBezierPath对象
UIBezierPath *aPath = [UIBezierPathbezierPath];
//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 = [UIBezierPathbezierPathWithOvalInRect:CGRectMake(100-5/2.0, 0, 5, 5)];
[aPath appendPath:path];
//(2)加到CAShapeLayer,效果出来了
CAShapeLayer *shapelayer = [CAShapeLayerlayer];
//设置边框颜色
shapelayer.strokeColor = [[UIColorredColor]CGColor];
//设置填充颜色
shapelayer.fillColor = [[UIColorwhiteColor]CGColor];
//就是这句话在关联彼此(UIBezierPath和CAShapeLayer):
shapelayer.path = aPath.CGPath;
[self.view.layeraddSublayer:shapelayer];
}
