iOS常用宏 定义

iOS开发过程中,使用的一些常用宏定义


  • 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 )

    //屏宽
    #define kScreenWidth \
    ([[UIScreen mainScreen] respondsToSelector:@selector(nativeBounds)] ? [UIScreen mainScreen].nativeBounds.size.width/[UIScreen mainScreen].nativeScale : [UIScreen mainScreen].bounds.size.width)
    //屏高
    #define kScreenHeight \
    ([[UIScreen mainScreen] respondsToSelector:@selector(nativeBounds)] ? [UIScreen mainScreen].nativeBounds.size.height/[UIScreen mainScreen].nativeScale : [UIScreen mainScreen].bounds.size.height)
    //屏的size(宽、高)
    #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)

    #define IS_IPHONE_6P (IS_IPHONE && SCREEN_MAX_LENGTH == 736.0)
    


  • 判断设备的操做系统是不是ios7

    #define IOS7 ([[UIDevice currentDevice].systemVersion doubleValue] >= 7.0]
    


  • 判断当前设备是不是iphone5 (远古时期,单纯判断高度。。)

    #define kScreenIphone5 (([[UIScreen mainScreen] bounds].size.height)>=568)
    





  • 获取当前屏幕的高度

    #define kMainScreenHeight ([UIScreen mainScreen].applicationFrame.size.height)
    
  • 获取当前屏幕的宽度

    #define kMainScreenWidth  ([UIScreen mainScreen].applicationFrame.size.width)
    

iOS9之后 使用“[UIScreen mainScreen].bounds”属性


  • 定义一个“define函数

    #define TT_RELEASE_CF_SAFELY(__REF) { if (nil != (__REF)) { CFRelease(__REF); __REF = nil; } }
    


  • 判断是真机还是模拟器

        //iPhone Device
    #endif
    
    #if TARGET_IPHONE_SIMULATOR
        //iPhone Simulator
    #endif
    


  • 检查系统版本

    //当前版本 = 版本v 
    #define SYSTEM_VERSION_EQUAL_TO(v) ([[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedSame)
    
    //当前版本 > 版本v
    #define SYSTEM_VERSION_GREATER_THAN(v) ([[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedDescending)
    //当前版本 >= 版本v
    #define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v) ([[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)
    
    //当前版本 < 版本v
    #define SYSTEM_VERSION_LESS_THAN(v) ([[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)
    //当前版本 <= 版本v
    #define SYSTEM_VERSION_LESS_THAN_OR_EQUAL_TO(v) ([[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedDescending)
    






内存
  • 使用ARC和不使用ARC (ARC

    #if __has_feature(objc_arc)
        //compiling with ARC
    #else
        // compiling without ARC
    #endif
    
    #pragma mark - common functions
    #define RELEASE_SAFELY(__POINTER) { [__POINTER release]; __POINTER = nil; }
    


  • 释放一个对象

    #define SAFE_DELETE(P) if(P) { [P release], P = nil; }
    

    #define SAFE_RELEASE(x) [x release];x=nil
    



图片
  • 读取 本地图片

    #define LOADIMAGE(file,ext) [UIImage imageWithContentsOfFile:[NSBundle mainBundle] pathForResource:file ofType:ext]
    


  • 定义UIImage对象 (路径

    #define IMAGE(A) [UIImage imageWithContentsOfFile:[NSBundle mainBundle] pathForResource:A ofType:nil]
    

建议使用这两种宏定义,性能高于下者。


  • 定义UIImage对象

    #define ImageNamed(_pointer) [UIImage imageNamed:[UIUtil imageName:_pointer]
    



颜色类
  • rgb颜色转换(16进制 --> 10进制

    #define UIColorFromRGB(rgbValue) [UIColor colorWithRed:((float)((rgbValue & 0xFF0000) >> 16))/255.0 green:((float)((rgbValue & 0xFF00) >> 8))/255.0 blue:((float)(rgbValue & 0xFF))/255.0 alpha:1.0]
    


  • 带有RGBA的颜色设置 (A:alpha)

    #define COLOR(R, G, B, A) [UIColor colorWithRed:R/255.0 green:G/255.0 blue:B/255.0 alpha:A]
    


  • 获取RGB颜色

    #define RGBA(r,g,b,a) [UIColor colorWithRed:r/255.0f green:g/255.0f blue:b/255.0f alpha:a]
    
    #define RGB(r,g,b) RGBA(r,g,b,1.0f)
    


  • 背景色

    #define BACKGROUND_COLOR [UIColor colorWithRed:242.0/255.0 green:236.0/255.0 blue:231.0/255.0 alpha:1.0]
    


  • 清除背景色

    #define CLEARCOLOR [UIColor clearColor]
    
    #pragma mark - color functions
    #define RGBCOLOR(r,g,b) [UIColor colorWithRed:(r)/255.0f green:(g)/255.0f blue:(b)/255.0f alpha:1]
    #define RGBACOLOR(r,g,b,a) [UIColor colorWithRed:(r)/255.0f green:(g)/255.0f blue:(b)/255.0f alpha:(a)]
    



其他
  • 方正黑体简体字体定义

    #define FONT(F) [UIFont fontWithName:@"FZHTJW--GB1-0" size:F]
    


  • 定义一个API

    #define APIURL @"http://xxxxx/"
    


  • 登录API

    #define APILogin [APIURL stringByAppendingString:@"Login"]
    



  • 设置View的tag()属性

    #define VIEWWITHTAG(_OBJECT, _TAG) [_OBJECT viewWithTag: _TAG]
    


  • 程序的本地化,引用国际化的文件

    #define MyLocal(x, ...) NSLocalizedString(x, nil)
    


  • GCD

    #define BACK(block) dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), block)
    
    #define MAIN(block) dispatch_async(dispatch_get_main_queue(),block)
    


  • NSUserDefaults 实例化

    #define USER_DEFAULT [NSUserDefaults standardUserDefaults]
    


  • 由角度获取弧度

    #define degreesToRadian(x) (M_PI * (x) / 180.0)
    
  • 由弧度获取角度

    #define radianToDegrees(radian) (radian*180.0)/(M_PI)
    


  • 单例化一个类

    #define SYNTHESIZE_SINGLETON_FOR_CLASS(classname) \
    \
     static classname *shared##classname = nil; \
    \
    
     + (classname *)shared##classname \
    { \
    
    @synchronized(self) \
    { \
    
     if (shared##classname == nil) \
    { \
    
     shared##classname = [self alloc] init]; \
    } \
    
    } \
    \
    
     return shared##classname; \
    } \
    \
    
     + (id)allocWithZone:(NSZone *)zone \
    { \
    
    @synchronized(self) \
    { \
    
     if (shared##classname == nil) \
    { \
    
     shared##classname = [super allocWithZone:zone]; \
     return shared##classname; \
    } \
    } \
    \
    
     return nil; \
    } \
    \
    
    - (id)copyWithZone:(NSZone *)zone \
    { \
    
     return self; \
    }
    
    #endif
    



后续有的话,会继续添加进来。
