iPhone app will push view controller in simulator but not on device
<p>I am using a UIButton to call the following IBAction to show a view controller, as far as I am aware this is a normal way of doing this? it works perfectly in the 4.3 simulator but when I run it on a 4.3 iPod the button presses, the code below is called but nothing happens, no error, no feedback, …any ideas?</p>

<pre><code>-(void)showAddNewUserView{  
    AddNewUserViewController *AddNewUserView = [[AddNewUserViewController alloc]init];
    [AddNewUserView setHidesBottomBarWhenPushed:YES];  
    [self.navigationController pushViewController:AddNewUserView animated:NO];  
}
</code></pre>
