PLeakSniffer
We are building controllers most of the time, memory leaks happen within controllers. Retain cycle stops controller from being released, UIView objects within controllers somehow get held by other objects, PLeakSniffer shows its value in such circumstances, it provides suggestions, but guarantees nothing.
It is your duty to set a breakpoint in the suspicous object's dealloc, and reveal the only truth.
Capability
PLeakSniffer can help detect memory leaks, including UIViewController, UIView, and all custom Properties. It provides suggestions with suspicious objects, prints a log message in the console like:
Detect Possible Controller Leak: %@
Detect Possible Leak: %@
