我需要在发布版本期间删除我的项目中存在的所有 NSLOG。我已尝试使用以下代码，但仍通过电话访问构建，但 NSLOG 仍显示在控制台中。
#ifdef DEBUG
#define debug_NSLog(format, ...) NSLog(format, ## __VA_ARGS__)
#else
#define debug_NSLog(format, ...)
#endif

To simply remove NSLogs:
简单地删除 NSLogs：
#define NSLog(s,...)
A #definewithout a substitution specified will substitute nothing, deleting anything that matches that #define. This works with simple token defines and with function-like defines like the above.
#define没有指定替换的A将不替换任何内容，删除与该 匹配的任何内容#define。这适用于简单的令牌定义和类似函数的定义，如上述。

Use the following code
使用以下代码
#ifdef DEBUGGING
# define DBLog(fmt,...) NSLog(@"%@",[NSString stringWithFormat:(fmt), ##__VA_ARGS__]);
#else
# define DBLog(...)
#endif
Make sure the compiler flags are properly set.
确保正确设置编译器标志。
Also, when you checked the console, did you check if you were using release mode ?
另外，当您检查控制台时，您是否检查过是否使用了发布模式？

Use this
用这个
#if TARGET_IPHONE_SIMULATOR
#define NSLog(fmt,...) NSLog((@"%s [Line %d] " fmt), __PRETTY_FUNCTION__, __LINE__, ##__VA_ARGS__);
#else
#define NSLog(...)
#endif
This will print NSLogif you are running it on simulator..
NSLog如果您在模拟器上运行它，这将打印..
