If I remove the table, and only navigate from one view to another, everything is fine. But if I add the table and the in the leaks-instruments click on the back btn at that very moment when the leak-instrument is analyzing, I get a growing leak. I get some small leaks QuartzCore mem_alloc. They are initially 8 Bytes each. Next time the leak appears they are 16 etc. Worse is a [NSCFArray copyWithZone:] leak which initially is 128 Bytes. I have been seaking for this leak for days now and I do not understand what the problem is. My whole app is navigating with tables and I assume (but do not actually have a clue) that my leaks are because of those tables... Any ideas?
