这篇博客总结了iOS开发中的一些常用宏定义，包括字符串、数组、字典的空判断，屏幕尺寸获取，设备类型检测，路径获取，NSLog的条件编译，颜色与字体操作，以及系统版本和内存管理相关的宏。还涵盖了图片加载、颜色转换和单例化等实用技巧。

字符串是否为空

1	`#define kStringIsEmpty(str) ([str isKindOfClass:[NSNull class]] \|\| str == nil \|\| [str length] < 1 ? YES : NO )`

数组是否为空

1	`#define kArrayIsEmpty(array) (array == nil \|\| [array isKindOfClass:[NSNull class]] \|\| array.count == 0)`

字典是否为空

1	`#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)
