Ensure a view remains full screen upon rotate - iphone

Question

I have a simple UIWebView that I've added to my UIViewController in the viewDidLoad method:
CGRect rect = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height);
self.webView = [[UIWebView alloc] initWithFrame:rect];
self.webView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
[self.view addSubview:self.webView];
And it looks great, but when I rotate the phone, the width and height remain the same so now it's too wide for the update view frame. I also tried using self.view.bounds, but it didn't make any difference.
So how do you ensure that a view that is fullscreen on load, stays the same size when rotated? (without using IB)

Answer 1

What you are doing is correct & should work in most scenarios. But since I have no idea about your View Stack. I will suggest a sure shot way -
- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
duration:(NSTimeInterval)duration
{
CGRect rect;
if(toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft||toInterfaceOrientation == UIInterfaceOrientationLandscapeRight)
{
rect = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height);
}
else
{
//some other dimensions.
}
self.webView = [[UIWebView alloc] initWithFrame:rect];
}

Because web view not called only once it need to be called again
to set the new frame
self.webView = [[UIWebView alloc] initWithFrame:rect];
so you have to register notification in viwewillappear or viewdidload
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(viewBecamePortrait:) name:#"orientationIsPortrait" object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(viewBecameLandscape:) name:#"orientationIsLandscape" object:nil];
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return YES;
}
-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration{
if (UIInterfaceOrientationIsPortrait(toInterfaceOrientation)) {
NSNotification* notification = [NSNotification notificationWithName:#"orientationIsPortrait" object:self];
[[NSNotificationCenter defaultCenter] postNotification:notification];
}else {
NSNotification* notification = [NSNotification notificationWithName:#"orientationIsLandscape" object:self];
[[NSNotificationCenter defaultCenter] postNotification:notification];
}
}
Then implement
-(void)viewBecameLandscape:(id)sender{
if(webview){
[webview.setframe(cgrectmake(x,y,width,height))];
}
}
-(void)viewBecamePortrait:(id)sender{
}
