How to get the height of a UIView without navigation bar?

I'm trying to add a UIWebView inside a clean UIViewController which in my Storyboard is embedded in a Navigation Controller:

UIWebView *webView =[[UIWebView alloc] initWithFrame:self.view.bounds)];
webView.delegate = self;
[self.view addSubview:webView];

The problem is, that the self.view.bounds.size.height is 460, which seems to be the height of the entire view including the navigation bar. I could subtract the value of self.view.frame.origin.y which is 20 and get the desired hight of 440, but are there a more common way to do this?

EDIT

Please take a look at my small code example here: http://uploads.demaweb.dk/WebViewTest.zip

When you scroll down to the bottom of the UIWebView, the last part of the web site is not shown, as the webView is to high.

I haven't found a better solution other than using topLayoutGuide (and optionally bottomLayoutGuide).

That is, adding your view to the controller's self.view and setting these constraints:

"H:|[view]|"
"V:[top][view][bottom]"

Where top is self.topLayoutGuide and bottom is self.bottomLayoutGuide.

As an example, see the configureViewController:fillWithSubView: method in AutolayoutHelper.

Solution

Setting the autoresizingMask in the UIWebView solved my problem:

self.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;

Default height is 480, 460 - height without status bar. 44px - height of navigation bar (you can access to height since it's a UIView - navBar.frame.size.height). So, your view height is 480-20-44 = 416. And you need to subtract from self.view.frame.size.height, not origin.y

Don't worry about it. The navigation controller takes care of resizing the view of the view controller under its jurisdiction. You would only override this view's frame if you would like it to be e.g. smaller to fit other subviews onto its superview.
