Getting EXC_BAD_ACCESS in using AQGridView with Xib

[Quamber]

I am using AQGridView with Xib file. I have set the basic Project just as explained in the Video by Evadne Wu. And i am moving to next Grid using expandFromRect from ExpansionDemo and the Grid is loaded fine but whenever i click anywhere on the grid i get EXC_BAD_ACCESS and exception is generated without any Log about the reason.

Also that the didSelectItemAtIndex doesn't get called even though i have set the self.gridView.delegate = self;

The problem was with overriding animations. I removed the animations ended updates and then called the controller and it worked fine
