Thanks a lot for your response. Unfortunately, it doesn't seem to be quite as
simple as that.
The executable I am working on is a screen saver.
My Info.plist looks like this:
<key>CFBundleName</key>
<string>${PRODUCT_NAME}</string>
<key>CFBundleExecutable</key>
<string>${EXECUTABLE_NAME}</string>
<key>CFBundleIdentifier</key>
<string>de.zach.${PRODUCT_NAME:rfc1034identifier}</string>
In the final packages, the variables are correctly replaced by the correct
executable names, i.e., "Foo" and "Foo2".
However, when I run the screen savers (in System Preferences), the name of my
screen saver, i.e., the value of CFBundleName is the same, whichever screen
saver I use. It happens to be the one of the screen saver that got started
first in SystemPreferences.
And since I base the name of the preferences file on the bundle name, both
screensavers Foo and Foo2 use the same preferences file.
Here is how I load the bundle and determine the name of the screen saver
running:
NSBundle * bundle = [NSBundle bundleForClass:[self class]];
exec_name_ = [[bundle infoDictionary] objectForKey:@"CFBundleName"];
I tried
NSBundle * bundle = [NSBundle mainBundle];
but that loads the bundle of SystemPreferences!
I was considering to use [NSBundle bundleWithIdentifier: @"de.zach.Foo"] but I
can't hard-code the identifier, since I don't know which screensaver it will be.
Is there something like preprocessor macro expansion in Obj-C? Something like
@"de.zach." ## PRODUCT_NAME
(that is C++ syntax, where PRODUCT_NAME is a preprocessor token, which can be
set on the command line of gcc).
Does anyone know how to do this properly?
Thanks a lot in advance.
Best regards,
Gabriel.
