在pch文件中添加
#ifdef DEBUG
#define NSLog(FORMAT, ...) {\
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];\
[dateFormatter setDateStyle:NSDateFormatterMediumStyle];\
[dateFormatter setTimeStyle:NSDateFormatterShortStyle];\
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss.SSSS"]; \
NSString *str = [dateFormatter stringFromDate:[NSDate date]];\
fprintf(stderr,"%s %s:%d %s\n",[str UTF8String],[[[NSString stringWithUTF8String:__FILE__] lastPathComponent] UTF8String],__LINE__,[[NSString stringWithFormat:FORMAT,##__VA_ARGS__] UTF8String]);\
}
#else
#define NSLog(FORMAT, ...) nil
#endif
就好了(*^__^*) …
