宏定義在很多方面都會使用，例如定義高度、判斷iOS系統(tǒng)、工具類，還有諸如文件路徑、服務(wù)端api接口文檔。為了對宏能夠快速定位和了解其功能，我們最好在定義的時候?qū)⑵浞湃胩囟ǖ念^文件中，下面我拋磚引玉，對一些常用的宏進行分類、分文件定義，希望對大家有所幫助。
定義尺寸類的宏
DimensMacros.h//狀態(tài)欄高度#define STATUS_BAR_HEIGHT 20//NavBar高度#define NAVIGATION_BAR_HEIGHT 44//狀態(tài)欄 ＋ 導(dǎo)航欄 高度#define STATUS_AND_NAVIGATION_HEIGHT ((STATUS_BAR_HEIGHT) + (NAVIGATION_BAR_HEIGHT))//屏幕 rect#define SCREEN_RECT ([UIScreen mainScreen].bounds)#define SCREEN_WIDTH ([UIScreen mainScreen].bounds.size.width)#define SCREEN_HEIGHT ([UIScreen mainScreen].bounds.size.height)#define CONTENT_HEIGHT (SCREEN_HEIGHT - NAVIGATION_BAR_HEIGHT - STATUS_BAR_HEIGHT)//屏幕分辨率#define SCREEN_RESOLUTION (SCREEN_WIDTH * SCREEN_HEIGHT * ([UIScreen mainScreen].scale))//廣告欄高度#define BANNER_HEIGHT 215#define STYLEPAGE_HEIGHT 21#define SMALLTV_HEIGHT 77#define SMALLTV_WIDTH 110#define FOLLOW_HEIGHT 220#define SUBCHANNEL_HEIGHT 622.定義沙盒目錄文件的宏
