Leak - GeneralBlock-3584

Question

When i try to check leaks of my iPhone App using Instruments, everything is just fine. Same App on actual real device shows this leak for a few times during the app launch.

Answer 1

You have nothing to worry about, this is false positive from Instruments.
It has to do with freeing resources of the thread that has being terminated. They just hang around until next thread is done and cleans resources after the one which is terminated previously. Instruments take this for a 'leak', but it's a feature of pthreads implementation on the iOS which in perfect world would be handled differently. More on this on the Apple's dev forum here and here.
