UIToolbar slides up and UIView slides down in displayed view
<p>UIButton from the <code>UIToolbar</code> on the <code>Mainviewcontroller</code> when displays <code>UIView</code>, <code>UIToolbar</code> slides up in the <code>View</code> displayed. From the <code>View</code> when <code>infobutton</code> is pressed to present modalviewcontroller and upon dismissal modalviewcontroller slides down.</p>

<p><code>UIToolbar</code> and <code>Modalviewcontroller</code> both are behaving normal in the <code>Mainviewcontroller</code> i.e <code>UIToolbar</code>not sliding up and <code>Modalviewcontroller</code> not sliding down upon dismissal.</p>

<pre><code>- (void)displayviewsAction:(id)sender
{
   self.view = [[[UIView alloc] initWithFrame:[[UIScreen mainScreen] bounds]]autorelease]; 

  [self.view setFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];

   PageOneViewController *viewController = [[[PageOneViewController alloc] init]autorelease];

   [self.view addSubview:viewController.view];

   [self.view addSubview:self.toolbar];

}
</code></pre>

<p>Any ideas why it is happening and what should i do to fix it.</p>
