基础类BaseViewController(未验证了)

这个类的作用是“适配”，让所有继承它的子类自动适配各种版本及屏幕尺寸的情况，自动适配显示和隐藏状态栏的情况，自动适配屏幕旋转的情况。

IOS  自定义  控件

   这个类比较适合纯代码开发项目，它的内部有两个公共属性，都是 UIView。一个作为自定义导航栏的superView，另作为除导航栏外的其他界面元素的superView。

   它会自动监测当前设备是什么IOS版本，设备的屏幕尺寸是多少。因为用到了autolayout,所以自动适配屏幕旋转。

具体代码如下：

001 #import <UIKit/UIKit.h>
002
003 @interface BaseViewController : UIViewController
