copied!<p>Bra, <code>UIViewControllers</code> have only one UIView as part of their guts.</p> <p>That is, "view" ... i.e. ... the actual property <code>view</code>, as in <code>self.view = something</code> or <code>view.hidden = YES</code>.</p> <p>However you can, of course, <strong>add as many subviews as you like</strong> to <strong><em>that view</em></strong>.</p> <p>This is how views are used normally. Almost every <code>.view</code> has subviews inside it.</p> <pre><code>UIView *bottomThing = [[UIView alloc] init]; bottomThing.frame = CGRectMake whatever UIView *otherThing = [[UIView alloc] init]; otherThing.frame = CGRectMake whatever [view addSubview:bottomThing]; [view addSubview:otherThing]; </code></pre> <p>In the example, we added two subviews to our main "built-in" view, which you refer to as simply "view". So we added bottomView to our "view" and we added topView to our "view."</p> <p>The subviews you add could be either plain old UIView, or, your own special subclass of UIView.</p> <pre><code>MySpecialView *bottomThing = [[UIView alloc] init]; bottomThing.frame = CGRectMake whatever ExtraordinaryView *otherThing = [[UIView alloc] init]; otherThing.frame = CGRectMake whatever [view addSubview:bottomThing]; [view addSubview:otherThing]; </code></pre> <p>(I guess FTR conceivably you could subclass <code>UIViewController</code> to have more than one view inside it, but that's completely pointless and irrelevant to this question.)</p> <p>From your <code>UIViewController</code> you can manipulate the subviews in any way you want.</p> <p>For example <code>[bottomThing doStuff:3.7]</code>, <code>bottomThing.hidden=YES</code>, etc etc.</p> <p>Once again it is absolutely normal to add more subviews inside your main "view" - this is the basic way in which iPhone apps are made. There is only one ".view" - you add more views inside it as you wish. Hope It Helps.</p>
