Question: I've just installed xcode 7 with ios 9.1 and I get this warning on a webview:

> 
> Null passed to a callee that requires a non-null argument

This is the code that fires the error:

```
-(void)viewWillDisappear:(BOOL)animated
{
    if(exitView)
        [ytView.webView loadHTMLString:nil baseURL:nil];
}

```

This way when the user goes back the webView (that plays a YT video) stops, it worked fine before, why does it gives this warning now?
How can I fix it?

Answer: 
```
[ytView.webView loadHTMLString:"" baseURL: [NSURL URLWithString:@"http://"] ];

```

regards
change the return type in CDVInAppBrowser.m at lines..

```
732    [self.webView loadHTMLString:@"" baseURL:nil];
1002  (UIInterfaceOrientationMask)supportedInterfaceOrientations

```
