Error when testing application on iPhone, but no error in simulator

I get the below error when I test my application on my iPhone, yet the error doesnt occur in the Simulator. Its when I load up my rootViewController which is a UITableView. I am relatively new to iOS programming, and I was just wondering if anybody could shed any light on it! Regards, Michael. Use this code to go to my RootView.

- (IBAction)goToRootView {
RootViewController *rootViewController = [[RootViewController alloc] initWithStyle:UITableViewStyleGrouped];
[self.navigationController pushViewController:rootViewController animated:YES];
[rootViewController release];

}

It looks like the problem is in your implementation of [RootViewController tableView:numberOfRowsInSection:]. You are trying to access a member of a NSMutableArray that is empty - hence the error 'index 0 beyond bounds for empty array'.

Your error is an index 0 beyond bounds for empty array error. Put breakpoints on the lines where you access arrays. When you find out which array is causing the problem, either the solution will be trivial, or you can add a bit more to your question and ask for further help.
