scrollViewDidScroll delegate is invoking automatically
===

I am using scrollViewDidScroll delegate in my application.

But, many times, even though I dint start scrolling, this delegate is getting invoked which is creating a lot of problem. I heard that even when contentSize for a particular scroll view is set then at that time also this delegate i.e., `scrollViewDidScroll` will invoke.

What are the different scenarios in which this delegate gets invoked. What are the steps to control this?

Can I set any parameter to handle this?
