在项目中合理的使用一些宏，可以很大的提高代码效率，代码简洁度！下面我就列举一些我常用的宏，随着项目的进行，我会持续更新！
在这里呢，我一般是把常用宏分类写：基础宏，颜色宏，地址宏，通知文字等常量
- 基础宏
/** MainScreen bounds */
#define Main_Screen_Bounds [[UIScreen mainScreen] bounds]
/** 屏幕宽高 */
#define kLFSCREEN_W [UIScreen mainScreen].bounds.size.width
#define kLFSCREEN_H [UIScreen mainScreen].bounds.size.height
/** 导航栏的高度 */
#define VIEW_TOP_HEIGHT (IOS7_OR_LATER ? 64.0f : 44.0f)

#define kstatusBarSize [[UIApplication sharedApplication] statusBarFrame].size
/** 屏幕尺寸 */
