篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了iOS常用宏定义相关的知识,希望对你有一定的参考价值。

  • 字符串是否为空

    #define kStringIsEmpty(str) ([str isKindOfClass:[NSNull class]] || str == nil || [str length] < 1 ? YES : NO )
  • 数组是否为空

    #define kArrayIsEmpty(array) (array == nil || [array isKindOfClass:[NSNull class]] || array.count == 0)
  • 字典是否为空

    #define kDictIsEmpty(dic) (dic == nil || [dic isKindOfClass:[NSNull class]] || dic.allKeys == 0)
  • 是否是空对象

      #define kObjectIsEmpty(_object) (_object == nil   || [_object isKindOfClass:[NSNull class]]   || ([_object respondsToSelector:@selector(length)] && [(NSData *)_object length] == 0)   || ([_object respondsToSelector:@selector(count)] && [(NSArray *)_object count] == 0))
  • 获取屏幕宽度与高度 ( " \ ":连接行标志,连接上下两行 )

    #define kScreenWidth \
      ([[UIScreen mainScreen] respondsToSelector:@selector(nativeBounds)] ? [UIScreen mainScreen].nativeBounds.size.width/[UIScreen mainScreen].nativeScale : [UIScreen mainScreen].bounds.size.width)
    #define kScreenHeight \
      ([[UIScreen mainScreen] respondsToSelector:@selector(nativeBounds)] ? [UIScreen mainScreen].nativeBounds.size.height/[UIScreen mainScreen].nativeScale : [UIScreen mainScreen].bounds.size.height)
    #define kScreenSize \
      ([[UIScreen mainScreen] respondsToSelector:@selector(nativeBounds)] ? CGSizeMake([UIScreen mainScreen].nativeBounds.size.width/[UIScreen mainScreen].nativeScale,[UIScreen mainScreen].nativeBounds.size.height/[UIScreen mainScreen].nativeScale) : [UIScreen mainScreen].bounds.size)
