Is there any way to force/cajole/encourage Interface Builder into running the C preprocessor when scanning source files for IBOutlet references?

If a BOOL has a nice short name, it's easy enough to write: myBOOL = !myBOOL; But what if the BOOL has a long name? objectWithLongishName.memberWithLongishName.submember.myBOOL = !(objectWithLongishName.memberWithLongishName.submember.myBOOL); . . . does not look so pretty. I'm wondering if there is an easy way to toggle the BOO...

Basically I'm trying to find a solution to my issue with sharing an object. I've had a look at SpringBoard's implementation and it looks as if SpringBoard is providing a framework which can be used to retrieve SBDisplay objects (which are basically CALayers). I know this specific issue is related to iPhones, but I also know that this is...

Hello, I'm using the IKImageBrowserView by supplying it with image objects myself. When the browserview requests for an image, in other languages, i'd check if i have it cached somewhere and return it if i do. Otherwise, i'd load, cache it and then return it. But in cocoa it seems that the IKImageBrowserView caches the images itself. So...
