IOS Custom Warning Prompt (method + macro)--imitate MJ

1, method

It's best to get a single class, defined as a class method.

All know the debug and release of iOS, so I defined a macro like this from the beginning:

#ifdef DEBUG

#define ZHHLOG (...) NSLog (__va_args__)

#else

#define ZHHLOG (...)

#endif

#define MAKECHAR (param) @ #param

How to use

2, macro

Define macros, without the trouble above, get directly into a public. h Okle.

Code:

#ifdef DEBUG

#define ZHHLOG (...) NSLog (__va_args__)

#else

#define ZHHLOG (...)

#endif

#define ZHHASSERTPARAMNOTNIL2 (param, returnvalue) \

ZHHAssert2 (param, [[NSString stringwithformat:@ #param] stringbyappendingstring:@ "parameter cannot be nil"], returnvalue)

#define ZHHASSERT2 (condition, desc, returnvalue) \

if ((condition) = = NO) {\

NSString *file = [NSString stringwithutf8string:__file__]; \

Zhhlog (@ "\ n Warning File:%@\n warning Line: line%d \ n Warning Method:%s\n Warning Description:%@", File, __line__, __function__, DESC); \

Return returnvalue; \

}

Usage:

ZHHAssertParamNotNil2 (nil, nil)
