thanks, I based my solution on that. As I'm writing ObjC I use a
shell script in conjunction with an ObjC class:
=== Shell script ===
#/bin/sh
now=$(date)
perl -p -i -e "s/return @\"[^\"]*\"/return \@\"$now\"/" GFFBuildInfo.m
=== ObjC Class ===
@implementation GFFBuildInfo
+ (NSString *) buildDate
{
return @"Wed Sep 15 17:01:08 CEST 2004";
}
@end
