此分类包括以下的功能:
- UIView的fram相关属性的获区与设置。
比如可以这样设置view的x和size代码：UIView * view = [UIView new];
view.left = 20;
view.size = CGSizeZero; - 移除所有子View和获得tag对应的view。
比如可以这样移除subview[view removeAllSubviews];
- 获得View最近的ViewController。
比如可以这样获得离View最近的ViewController[view viewController];
- 添加分隔线
比如在view的底部添加一条分隔线：[view addLineBottom];
这里使用默认颜色和默认线宽。你也可以通过传递参数来定制你自己的添加线的方法。
