iOS 에서 자주 사용 하 는 매크로 정의 요약

머리말
매크로 정 의 는 C 학과 개발 에서 매우 중요 한 역할 을 한다 고 할 수 있다.개발 절 차 를 간소화 하고 업무 효율 을 향상 시 키 기 위해 평소에 자주 사용 하 는 매크로 정 의 를 수집 했다.앞으로 비정 기적 으로 업데이트 할 것 이다.
1.UI 요소

//NavBar  
#define NAVIGATIONBAR_HEIGHT 44

//StatusBar  
#define STATUSBAR_HEIGHT 20

//       、  
#define SCREEN_WIDTH ([UIScreen mainScreen].bounds.size.width)
#define SCREEN_HEIGHT ([UIScreen mainScreen].bounds.size.height)

//      
#define CONTENT_HEIGHT (SCREEN_HEIGHT - NAVIGATIONBAR_HEIGHT - STATUSBAR_HEIGHT)

//KWindow
#define KWINDOW [UIApplication sharedApplication].keyWindow

//     
#define SCREEN_RESOLUTION (SCREEN_WIDTH * SCREEN_HEIGHT * ([UIScreen mainScreen].scale))

//    ＋       
#define STATUS_AND_NAVIGATION_HEIGHT ((STATUSBAR_HEIGHT) + (NAVIGATIONBAR_HEIGHT))

2.Log

//(   Log    ，          )
#define NSLog(format, ...) do {            \
fprintf(stderr, "<%s : %d> %s
",           \
[[[NSString stringWithUTF8String:__FILE__] lastPathComponent] UTF8String], \
__LINE__, __func__);              \
