iOS开发常用高效率宏

前言

github：https://github.com/xfxfxf

iOS开发当中，有很多用的多但是写起来比较繁琐的代码，比如获取屏幕的宽高，简直纠结的不行，之前在CSDN上面看到很多不错的总结。

iOS开发常用宏这里面就总结的很好，但是为什么字那么小。。。

我在这里重新录入，并添加一些自己写的，后续会继续更新一些好用的宏。

尺寸宏

#define StatusBar_HEIGHT 20#define NavigationBar_HEIGHT 44#define NavigationBarIcon 20#define TabBar_HEIGHT 49#define TabBarIcon 30#define SCREEN_WIDTH ([UIScreen mainScreen].bounds.size.width)#define SCREEN_HEIGHT ([UIScreen mainScreen].bounds.size.height) 

打印宏

//替换NSLog来使用，debug模式下可以打印很多方法名，行信息。#ifdef DEBUG#   define DLog(fmt, ...) NSLog((@"%s [Line %d] " fmt), __PRETTY_FUNCTION__, __LINE__, ##__VA_ARGS__);#else  #   define DLog(...)  #endif

//直接替换NSLog#if DEBUG  #define NSLog(FORMAT, ...) fprintf(stderr,"\nfunction:%s line:%d content:%s\n", __FUNCTION__, __LINE__, [[NSString stringWithFormat:FORMAT, ##__VA_ARGS__] UTF8String]);  #else  #define NSLog(FORMAT, ...) nil  #endif

//DEBUG  模式下打印日志,当前行以及弹出一个警告#ifdef DEBUG#   define ULog(fmt, ...)  { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:[NSString stringWithFormat:@"%s\n [Line %d] ", __PRETTY_FUNCTION__, __LINE__] message:[NSString stringWithFormat:fmt, ##__VA_ARGS__]  delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil]; [alert show]; }#else#   define ULog(...)#endif

#define ITTDEBUG#define ITTLOGLEVEL_INFO     10#define ITTLOGLEVEL_WARNING  3#define ITTLOGLEVEL_ERROR    1#ifndef ITTMAXLOGLEVEL#ifdef DEBUG#define ITTMAXLOGLEVEL ITTLOGLEVEL_INFO#else#define ITTMAXLOGLEVEL ITTLOGLEVEL_ERROR#endif#endif// The general purpose logger. This ignores logging levels.#ifdef ITTDEBUG#define ITTDPRINT(xx, ...)  NSLog(@"%s(%d): " xx, __PRETTY_FUNCTION__, __LINE__, ##__VA_ARGS__)#else#define ITTDPRINT(xx, ...)  ((void)0)#endif// Prints the current method's name.#define ITTDPRINTMETHODNAME() ITTDPRINT(@"%s", __PRETTY_FUNCTION__)// Log-level based logging macros.#if ITTLOGLEVEL_ERROR <= ITTMAXLOGLEVEL#define ITTDERROR(xx, ...)  ITTDPRINT(xx, ##__VA_ARGS__)#else#define ITTDERROR(xx, ...)  ((void)0)#endif#if ITTLOGLEVEL_WARNING <= ITTMAXLOGLEVEL#define ITTDWARNING(xx, ...)  ITTDPRINT(xx, ##__VA_ARGS__)#else#define ITTDWARNING(xx, ...)  ((void)0)#endif#if ITTLOGLEVEL_INFO <= ITTMAXLOGLEVEL#define ITTDINFO(xx, ...)  ITTDPRINT(xx, ##__VA_ARGS__)#else#define ITTDINFO(xx, ...)  ((void)0)#endif#ifdef ITTDEBUG#define ITTDCONDITIONLOG(condition, xx, ...) { if ((condition)) { \ITTDPRINT(xx, ##__VA_ARGS__); \} \} ((void)0)#else#define ITTDCONDITIONLOG(condition, xx, ...) ((void)0)#endif#define ITTAssert(condition, ...)           \do {  \if (!(condition)) { \[[NSAssertionHandler currentHandler]      \handleFailureInFunction:[NSString stringWithUTF8String:__PRETTY_FUNCTION__] \file:[NSString stringWithUTF8String:__FILE__]  \lineNumber:__LINE__      \description:__VA_ARGS__]; \}   \} while(0)

系统宏

//获取版本#define IOS_VERSION [[[UIDevice currentDevice] systemVersion] floatValue]#define CurrentSystemVersion [[UIDevice currentDevice] systemVersion]

//获取当前语言#define CurrentLanguage ([[NSLocale preferredLanguages] objectAtIndex:0])

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

//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)

内存宏

//使用ARC和不使用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

图片宏

//读取本地图片#define LOADIMAGE(file,ext) [UIImage imageWithContentsOfFile:[[NSBundle mainBundle]pathForResource:file ofType:ext]]//定义UIImage对象#define IMAGE(A) [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:A ofType:nil]]//定义UIImage对象//#define ImageNamed(_pointer) [UIImage imageNamed:[UIUtil imageName:_pointer]]//前两种宏性能高，省内存//第三个没有必要使用，因为我们可以使用Xcode的插件

颜色宏

// 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#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)]

其他宏

//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/"//登陆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)//G－C－D#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 有弧度获取角度#define degreesToRadian(x) (M_PI * (x) / 180.0)#define radianToDegrees(radian) (radian*180.0)/(M_PI)

单例宏

#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; \}
