UIWebView not resizing - objective-c

Question

I've tried everything I can think of to get my UIWebView to fill the screen automatically on an Iphone 4, 5 and Ipads. I've used auto resizing masks, tried setting the frame programmatically based on the device and still noting has worked.
This is not a scaling problem with the HTML that gets loaded the scroll bars are actually not where they should be.
What am I doing wrong? I know it shouldn't be this difficult.
#interface webview ()
#end
#implementation webview
#synthesize weber;
#synthesize suppressesIncrementalRendering;
static NSString* titled;
static NSString* urlholder;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
-(void)viewWillAppear:(BOOL)animated
{
[[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:YES];
}
-(void)viewDidDisappear:(BOOL)animated
{
[[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO];
}
- (void)viewDidLoad
{
[super viewDidLoad];
self.weber.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight);
self.title= titled;
NSString *fullURL = urlholder;
NSURL *url = [NSURL URLWithString:fullURL];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[weber setSuppressesIncrementalRendering:YES];
[weber loadRequest:requestObj];
wasLoaded = NO;
alertWasShown = NO;
weber.delegate = self;
}
- (void)webViewDidStartLoad:(UIWebView *)webView {
[[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:YES];
}
- (void)webViewDidFinishLoad:(UIWebView *)webView {
wasLoaded = YES; // Indicates that it finished loading.
[[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO];
}
-(void) setttl: (NSString*) titler
{
titled= titler;
}
-(void) setURL: (NSString*) url
{
urlholder= url;
}

Answer 1

Nowhere in your code do I see where you are setting the initial frame for the webview. The resizing masks determine how it resizes, but they do not determine the size of the view to start with.
It looks like you are using a xib, try setting the size of the webview to fit correctly in its superview. Then use InterfaceBuilder to set the resizing properties in the Size inspector.
Alternatively, you could set the size programmatically:
self.weber.frame = CGRectMake(0.0, 0.0, 200.0, 700.0);

Assuming the superview fills the screen you should assign the frame of the UIWebView as the bounds of its parent in viewDidLoad:
self.weber.frame = self.view.bounds;
If your UIWebView is being programmatically instantiated the code would look something like this:
-(void)viewDidLoad
{
[super viewDidLoad];
self.weber = [UIWebView new];
self.weber.frame = self.view.bounds;
[self.view addSubview:self.weber];
}

I just came across this question because I had a similar problem. What fixed it for me was setting the frame of my UIWebView in viewDidLayoutSubViews instead of in viewDidLoad. This was suggested by entonio in a comment on one of the other answers, but I'm putting it here as an answer so it's easier to find if someone else comes along.

It appears that storyboard overrides any code to resize UIWebView. If you're trying to load a dynamic html/css into a UIWebView and it won't resize on Orientation change: Try unchecking the "autolayout" setting.
Select .storyboard file
Go to identity qand type window (see link snapshot)
Uncheck "Use Auto Layout" in Interface Builder Document section.
