iOS常用的宏定义

1. NSLog宏

#define NSLog(format, ...) do { \

fprintf(stderr," %s\n", \[[[NSString stringWithUTF8String:__FILE__] lastPathComponent] UTF8String], \

__LINE__, __func__); \

(NSLog)((format), ##__VA_ARGS__); \

fprintf(stderr, "-------\n"); \

} while (0)

2. 打印方法名

#define ZZDPRINTMETHODNAME() ZZDPRINT(@"%s", __PRETTY_FUNCTION__)

3. Debug

#ifdef ZZDEBUG

#define ZZDCONDITIONLOG(condition, xx, ...) { if ((condition)) { \

ITTDPRINT(xx, ##__VA_ARGS__); \

} \

} ((void)0)

#else

#define ZZDCONDITIONLOG(condition, xx, ...) ((void)0)

#endif

4. 错误抛出

#define DgAssert(condition, ...)\

do {\

if (!(condition)) {\

[[NSAssertionHandler currentHandler]\

handleFailureInFunction:[NSString stringWithUTF8String:__PRETTY_FUNCTION__] \

file:[NSString stringWithUTF8String:__FILE__]\

lineNumber:__LINE__\

description:__VA_ARGS__];\

}\

} while(0)

5. 测试方法或代码执行时间

#define TICK  NSDate *startTime = [NSDate date]

#define TOCK  NSLog(@"Time: %f", [startTime timeIntervalSinceNow])

6. 定义编译环境

#ifndef __OPTIMIZE__
//这里执行的是debug模式下
else
//这里执行的是release模式下
#endif


//都注释为UAT环境
#define SERVER_PRODUCT_SWITCH // 生成地址 放开为生产地址
#define TEST_SERVER_SWITCH // 测试地址  放开为测试地址


#ifdef SERVER_PRODUCT_SWITCH     //——线上地址
//define something
//MARK: 测试地址
#elif defined TEST_SERVER_SWITCH
//define something
//MARK: UAT
#else // UAT
//define something
#endif

7. 模拟器或真机判断

#if defined (__i386__) || defined (__x86_64__)

//模拟器下执行

#else

//真机下执行

#endif

8. RGB颜色

#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)]

9. 角度弧度互换

#define degreesToRadian(x) (M_PI * (x) / 180.0)

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

10. 字符串操作

#define IS_STRING_NOT_EMPTY(sting)(sting && ![@"" isEqualToString:sting] && (NSNull *)sting!=[NSNull null])

#define IS_STRING_EMPTY(sting)(!sting || [@"" isEqualToString:sting] || (NSNull *)sting==[NSNull null])

#define SAFE_STRING(x)(IS_STRING_EMPTY(x))?(@""):(x)

11. 随机数

#define RANDOM_SEED() srandom(time(NULL))

#define RANDOM_INT(__MIN__, __MAX__) ((__MIN__) + random() % ((__MAX__+1) - (__MIN__)))
