iOS开发常用宏

设备

// 横屏
#define UI_IS_LANDSCAPE  ([UIDevice currentDevice].orientation == UIDeviceOrientationLandscapeLeft || [UIDevice currentDevice].orientation == UIDeviceOrientationLandscapeRight)

// iPad
#define UI_IS_IPAD   ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad)
// iPhone
#define UI_IS_IPHONE  ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)

#define UI_IS_IPHONE5           (UI_IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 568.0)
#define UI_IS_IPHONE6           (UI_IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 667.0)
#define UI_IS_IPHONE_PLUS       (UI_IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 736.0 || [[UIScreen mainScreen] bounds].size.width == 736.0) // Both orientations
#define UI_IS_IPHONE_X           (UI_IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 812.0)
// 屏幕尺寸
#define SCREEN_W   [UIScreen mainScreen].bounds.size.width
#define SCREEN_H   [UIScreen mainScreen].bounds.size.height

系统

#define IsIOS6Later ([[[UIDevice currentDevice] systemVersion] floatValue] >=6.0 ? YES : NO)
#define IsIOS7Later ([[[UIDevice currentDevice] systemVersion] floatValue] >=7.0 ? YES : NO)
#define IsIOS8Later ([[[UIDevice currentDevice] systemVersion] floatValue] >=8.0 ? YES : NO)
#define SUPPORT_IPHONE_OS_VERSION(version) ( __IPHONE_OS_VERSION_MIN_REQUIRED <= version && __IPHONE_OS_VERSION_MAX_ALLOWED >= version)


#define UserDefaults   [NSUserDefaults standardUserDefaults]
#define NotificationCenter     [NSNotificationCenter defaultCenter]

设置Debug模式下打印log,release模式下不打印

#ifdef DEBUG
#   define DebugLog(format, ...)   NSLog((@"[DEBUG]%s " format), __PRETTY_FUNCTION__, ##__VA_ARGS__);
#else
#   define DebugLog(...)
#   define NSLog(...)
#endif

颜色

//
#define RGBA(r,g,b,a)   [UIColor colorWithRed:(float)r/255.0f green:(float)g/255.0f blue:(float)b/255.0f alpha:a]

#define RGBACOLOR(r,g,b,a)  [UIColor colorWithRed:r green:g blue:b alpha:a]

#define HSVACOLOR(h,s,v,a)  [UIColor colorWithHue:h saturation:s value:v alpha:a]

#define MAIN_GREY  [UIColor colorWithRed:0.55 green:0.55 blue:0.56 alpha:1.00]
#define MAIN_GRAY  HEXCOLOR(0x999999)
#define BACK_GREY   HEXCOLOR(0xefefef)

字体大小(常规/粗体)

#define BOLDSYSTEMFONT(FONTSIZE)            [UIFont boldSystemFontOfSize:FONTSIZE]
#define SYSTEMFONT(FONTSIZE)                [UIFont systemFontOfSize:FONTSIZE]
#define FONT(NAME, FONTSIZE)                [UIFont fontWithName:(NAME) size:(FONTSIZE)]

常用方法

// 设置frame
#define RectMake(x,y,w,h)   CGRectMake(x,y,w,h)
// Max Y
#define GetViewMaxY(view)      CGRectGetMaxY((view).frame)

单例

#ifndef SINGLETON_GCD
#define SINGLETON_GCD(classname)                       \
                                                       \
+ (classname *)sharedInstance##classname {             \
                                                       \
    static dispatch_once_t oncePredicate;              \
    static classname * sharedInstance##classname = nil;\
    dispatch_once( &oncePredicate, ^{                  \
    sharedInstance##classname = [[self alloc] init];   \
    });                                                \
                                                       \
    return sharedInstance##classname;                  \
}
#endif
