title: Instruments, Increase in Allocations of iPhone application
body: <p>I am using UIPageViewController to load multiple view controllers. When I run my application in Instruments tool. I found that the allocations are moving to high margin. 
  Though I am releasing and making the class object to nil. The allocations keep on increasing when I move to and fro . What am I missing ? </p>
