NSInvalidArgumentException occur when you refer to non-existing object. You might have release datasource or tableview object in the class. — MrWaqasAhmed, May 02 '12 at 09:09
It seems the data source (seems to be an array) has got released at that time you call *realodData* method. — EmptyStack, May 02 '12 at 09:09
are you calling objectatindex method on an array or an nscfstring string? — sujith1406, May 02 '12 at 09:15
