IOS NSLog removing timestamps and other output styles

1. In the general project my NSLog will add the following code in the Prefix.pch file, which is guaranteed nslog not working in the non-debug state

12345

#ifdef debug#define NSLog (...) NSLog (__va_args__) #else # define NSLOG (...) #endif

2. If you do not do any processing in the project, the following information will be output, preceded by a timestamp

1	2014-11-07 08:25:40.885 zcsy[673:8937] cell height 258.684998

We modified the following macro as follows:

12345

#ifdef debug#define NSLog (FORMAT, ...) fprintf (stderr, "%s\n", [[NSString Stringwithformat:format, # #__VA_ARGS__] Utf8string]); #else # define NSLOG (...) #endif

After the above changes we can output pure content as follows:

1	Cell's Height 258.684998

We can use the better version I recommend to print our log:

12345

#ifdef debug#define NSLog (FORMAT, ...) fprintf (stderr, "%s:%d\t%s\n", [[[NSString stringwithutf8string:__file__] Lastpathcomponent] utf8string], __line__, [[NSString Stringwithformat:format, # #__VA_ARGS__] utf8string]); #else # Define NSLOG (...) #endif

So our output is this:

12	It will output the filename, and print the exact line number dealitemcell.m:307 cell's height 258.684998
