MLeaksFinder & FBRetainCycleDetector

MLeaksFinder

MLeaksFinder helps you find memory leaks in your iOS apps at develop time. It can automatically find leaks in UIView and UIViewController objects, present an alert with the leaked object in its View-ViewController stack when leaks happening. More over, it can try to find a retain cycle for the leaked object using FBRetainCycleDetector. Besides finding leaks in UIView and UIViewController objects, developers can extend it to find leaks in other kinds of objects.

FBRetainCycleDetector
Retain cycles are one of the most common ways of creating memory leaks. It's incredibly easy to create a retain cycle, and tends to be hard to spot it. The goal of FBRetainCycleDetector is to help find retain cycles at runtime. The features of this project were influenced by Circle.
