You can always subclass, turn off ARC for that file, and override -release or
-autorelease to breakpoint in. I’ve done that on occasion with particularly
tricky overrelease bugs (which actually turned out to be an under-autorelease
bug in some non-ARC code).

Yes. You can either use key-value coding: [[self valueForKey:myString] release];
or you can use the ObjC runtime functions to do exactly that.

You did not miss anything. Since a queue can run on any or multiple threads
(except the main queue), creating a runloop on it - and runloops are

Jens, I think you’ve got the question backwards: the public ivar is in the base

The disadvantage is if you need to use string constants across binaries (such
