Xcode - Understanding the Allocations Tool

When profiling an application, I notice that live bytes increase by about 250 KB every time I perform certain actions (including UIViews).

In the list of objects, the main (growing) criminal simply reads as "malloc 144 bytes".

Sometimes I used the Allocations tool to find objects that I have held on longer than I would like, but I'm not sure how to interpret the malloc objects.

Everyone is welcome any guide.
