iphone - ios tableview crash as soon as search start

Question

I want to use tableview + searchDisplay with two different source, that is, when user attempts to search on searchbar, it should searches from different an array, and display it.

The way I can do this is, distinguish source in table view delegate and treat different source when searchdisplay call table view delegate methods. So I did something like:

 - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
 {
   if(self.tableView == tableView){
     return [self.sourceArray objectAtIndex:section] count];
   }
   //search display
   return 5;

 }

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return self.tableView == tableView ? 3 : 1; 
}

but once I attempted to search on search bar ( as soon as text changed ), it just crashed with index out of bounds. I tried to debug it but couldn't find what is really wrong.

I'm not sure where this out of bound exception occur at, I'd appreciate any comment.
