> Closing the InAppBrowsers sometimes causes a crash on iOS.
> I think the problem is with the UIWebView delegate.
> Apple documentation states that the delegate should be set to nil before release but it is not done.
> See: https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIWebViewDelegate_Protocol/
> The following code in CDVInAppBrowserViewController seems to solve the problem:
> -(void)dealloc
> {
>     self.webView.delegate = nil;
> }
> The crashes are seen in an App that closes the IAB at 'loadstart'.
> I think this is required to get the crashes that occur around 1/10 times.
> The following error is seen at crashes when Zombie Objects are enabled:
> *** -[CDVWebViewDelegate respondsToSelector:]: message sent to deallocated instance 0x171846e70
