Facebook has released 3 objective-c based tools for automatic memory leak detection on iOS – FBRetainCycleDetector, FBAlloactionTracker and FBMemoryProfiler.

FBRetainCycleDetector finds retain cycles, FBAllocationTracker provides introspection of Objective-C objects, and FBMemoryProfiler uses FBRetainCycleDetector and FBAllocationTracker allowing you to browse objects and view their memory usage over time.

Here’s an image from the FBMemoryProfiler showing it in action:
