Converting between property names?


  • Subject: Converting between property names?
  • From: Rick Mann <email@hidden>

Are there functions provided in the Objective-C runtime to convert property names? For example, say I have a key name like "fooKey", and I want to get "FooKey", or the setter name "setFooKey" from it. I could do the name munging myself, but I wonder if there aren't edge cases. For example, "setURL" should covert to "URL", not "uRL".

In my particular case, I'm trying to implement functionality like +keyPathsForValuesAffecting<Key>. It takes a key name (usually something that starts with a lower-case letter) and changes it to start with an upper-case letter, then appends it to "keyPathsForValuesAffecting" to create the selector name.

Are those conversion methods provided anywhere? I looked through the Obj-C runtime and didn't see anything, but I didn't read every single page.

Thanks,
Rick
