iOS 常用的宏定义

屏幕尺寸

#define kscreenwidth [uiscreen mainscreen].bounds.size.width

#define kscreenheight [uiscreen mainscreen].bounds.size.height

手机型号

 #define kisiphone (ui_user_interface_idiom() == uiuserinterfaceidiomphone)

 #define kscreenmaxlength (max(kscreenwidth, kscreenheight))

 #define kscreenminlength (min(kscreenwidth, kscreenheight))

#define kstatusbarheight [[uiapplication sharedapplication] statusbarframe].size.height
//状态栏高度
#define statusbarheight (kisiphonex?44:20)
//标签栏高度
#define ktabbarheight (statusbarheight > 20 ? 83 : 49)
//导航栏高度
