- Thread-topic: Synthesize getter in a NSThread
Unless I misread the documentation on drain, adding a [pool drain]will
cause the pool to be deallocated. I tried it anyways, and I get a couple
of emits in the console.
// This message emits when a call to the getter is made
2011-05-21 20:23:39.515 LeakyThread[5947:5707] ***
__NSAutoreleaseNoPool(): Object 0x10011d720 of class NSCFString
autoreleased with no pool in place - just leaking
// This message emits when a call to pool drain is called.
2011-05-21 20:23:39.515 LeakyThread[5947:5707] *** -[NSAutoreleasePool
drain]: This pool has already been drained, do not release it (double
release).
Still not sure what the problem is.
