1、软件系统

/** App版本 */
#define APP_VERSION [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"]
/** 获取系统版本 */
#define ios_SYSTEM_VERSION [[[UIDevice currentDevice] systemVersion] floatValue]
#define CurrentSystemVersion ［UIDevice currentDevice] systemVersion]
/** 判断 iOS 8 或更高的系统版本 */
#define IOS_VERSION_8_OR_LATER (([[[UIDevice currentDevice] systemVersion] floatValue] >=8.0)? (YES):(NO))
/** 判断设备的操做系统是不是ios7 */
#define IOS7 (［[UIDevice currentDevice].systemVersion doubleValue] >= 7.0]

/** 检查系统版本 */
#define SYSTEM_VERSION_EQUAL_TO(v) (［[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedSame)
#define SYSTEM_VERSION_GREATER_THAN(v) (［[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedDescending)
#define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v) (［[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)
#define SYSTEM_VERSION_LESS_THAN(v) (［[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)
#define SYSTEM_VERSION_LESS_THAN_OR_EQUAL_TO(v) (［[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedDescending)

/** 获取当前屏幕的高度 */
#define CHScreenH ([UIScreen mainScreen].applicationFrame.size.height)
/** 获取当前屏幕的宽度 */
#define CHScreenW ([UIScreen mainScreen].applicationFrame.size.width)

/** 判断是真机还是模拟器 */
#if TARGET_OS_IPHONE
    //iPhone Device
#endif
#if TARGET_IPHONE_SIMULATOR
    //iPhone Simulator
#endif

/** 判断是否为 iPhone 5SE */
#define iPhone5SE [[UIScreen mainScreen] bounds].size.width == 320.0f && [[UIScreen mainScreen] bounds].size.height == 568.0f
/** 判断是否为iPhone 6/6s */
#define iPhone6_6s [[UIScreen mainScreen] bounds].size.width == 375.0f && [[UIScreen mainScreen] bounds].size.height == 667.0f
/** 判断是否为iPhone 6Plus/6sPlus */
#define iPhone6Plus_6sPlus [[UIScreen mainScreen] bounds].size.width == 414.0f && [[UIScreen mainScreen] bounds].size.height == 736.0f
/** 判断当前设备是不是iphone5 */
#define CHcreenIphone5 ((［UIScreen mainScreen] bounds].size.height)>=568)

/** 是否iPad */
#define isPad (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
/** 是否iPad */
#define someThing (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)? ipad: iphone

/** 判断是否 Retina屏 */
#define isRetina ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(640, 960), ［UIScreen mainScreen] currentMode].size) : NO)

#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 80000 // 当前Xcode支持iOS8及以上
    #define SCREEN_WIDTH ([[UIScreen mainScreen] respondsToSelector:@selector(nativeBounds)]?[UIScreen mainScreen].nativeBounds.size.width/[UIScreen mainScreen].nativeScale:[UIScreen mainScreen].bounds.size.width)

    #define SCREEN_SIZE ([[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)
#else
    #define SCREEN_WIDTH [UIScreen mainScreen].bounds.size.width
