摘要：
判断给定的点是否被一个CGRect包含,可以用CGRectContainsPoint函数BOOLcontains= CGRectContainsPoint(CGRect rect, CGPoint point);判断一个CGRect是否包含再另一个CGRect里面,常用与测试给定的对象之间是否又重叠BOOLcontains= CGRectContainsRect(CGRect rect1, CGRect rect2);判断两个结构体是否有交错.可以用CGRectIntersectsRectBOOL contains = CGRectIntersectsRect(CGRect rect1, CG 阅读全文
