screen blacks out when loading a html file in web view iOS - ios

Question

I am trying to load a html file in a web view and the screen blacks out.
Hierachy of view controller are:
View
Web View
Navigation Item
This is the tab and there is navigation controller to present the View Controller.
Code:
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
self.webView = [[UIWebView alloc] init];
self.view.backgroundColor = [UIColor colorWithPatternImage:[JLTBackgroundHelper getBackgroundImageForLandingView]];
self.webView.opaque = NO;
self.webView.backgroundColor = [UIColor clearColor];
UIViewController *rootVC = [[UIViewController alloc] init];
rootVC.title = #"Contact JLT Sport";
rootVC.view = self.webView;
self.viewControllers = #[rootVC];
NSString *fileName;
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
// iPad-specific
fileName = #"contact_ipad";
} else {
// iPhone-specific
fileName = #"contact";
}
NSString *htmlFile = [[NSBundle mainBundle] pathForResource:fileName ofType:#"html" inDirectory:#"Assets/web"];
NSURL *url = [NSURL fileURLWithPath:htmlFile];
NSURLRequest *request =[NSURLRequest requestWithURL:url];
[_webView loadRequest:request];
_webView.delegate= self;
}
- (BOOL) webView:(UIWebView*)wv shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navType
{
if (navType == UIWebViewNavigationTypeLinkClicked
&& [request.URL.scheme hasPrefix:#"http"])
{
[[UIApplication sharedApplication] openURL:request.URL];
return NO;
}
return YES;
}
Not sure whats going wrong. tried for more than 5 hours but no luck.

Instead of
self.viewControllers = #[rootVC];
Try this
[self presentViewController:rootVC animated:NO completion:nil];
If presenting the controller in viewDidLoad gives some problem, then do it in viewDidAppear. First of all I'm not clear why you are creating another view controller within viewDidLoad of a controller and adding the subview to that.
