The approach we use is:
-----------------------
#ifdef INFO_PLIST
#define STRINGIFY(_x) _x
#else
#define STRINGIFY(_x) # _x
#endif
#define kAppName STRINGIFY(MyNewApp)
#define kAppVersion STRINGIFY(1.0a1)
#define kURLHomePage "http://www.mynewapp.com/";
-----------------------
Where INFO_PLIST is defined in INFOPLIST_PREPROCESSOR_DEFINITIONS. This
will give you the raw MyNewApp token in the .plist, and "MyNewApp" in
your source code.
Note that you can't use STRINGIFY() with all strings - for kURLHomePage,
the presence of the // sequence produces an "unterminated argument list
invoking macro" error.
If you replace it with '/\/' you'll get the correct string in the C
code, but will end up with an extra '\' in the .plist (and similarly for
breaking it into two strings: the C code will merge them, the .plist
won't). For now we just assume this macro is C-only.
One remaining problem (rdar://4177551) is that .strings files can't be
preprocessed, so if your InfoPlist.strings has things like:
-----------------------
CFBundleGetInfoString = "MyNewApp 1.0a1, Copyright Me.";
-----------------------
Then you'll still need to keep that version number in sync manually (in
each of your localised InfoPlist.strings files).
Although invoking the preprocessor is a good step forward, what I would
really like is some kind of dedicated preprocessor as per CodeWarrior.
Ideally without the .plc-style syntax, but something that could:
1. Preprocess .plist and .strings files
2. Automatically de-quote quoted strings in .plist files (but not in
.strings files)
3. Automatically concatenate strings ("foo" "bar" == "foobar")

We use 3.3 for all our projects, and haven't seen this - is it 3.3
you're using, or 3.1?
