我想绘制一个大圆圈并放置一些较小的圆圈,如下图所示

我绘制了大卷 - (void)drawRect:(CGRect)rect

CGFloat rectX = self.frame.size.width / 2;
CGFloat rectY = self.frame.size.height / 2;

CGFloat width = self.frame.size.width-30;
CGFloat height = self.frame.size.width -30;

CGFloat centerX = rectX - width/2;
CGFloat centerY = rectY - height/2;


UIBezierPath *bezierPath = [UIBezierPath bezierPathWithOvalInRect:CGRectMake(centerX, centerY, width, height)];

[[UIColor blackColor] set];
[bezierPath stroke];

让我们说我想在圆上找到10个等间距的点,以绘制10个较小的红色圆圈.有智能解决方案吗？先感谢您.
