iOS App Crashes When WebView Swiped

In my app, I go to a webpage which is a keynote file. Users can browse that keynote and follow along on their own device. I allow all rotations, and it rotates fine. To make more room when in landscape, I have it hide the navigation bar on swipe. When I do this in portrait, it hides it and all is fine. When I do it in landscape, I get a crash. All I get in console is Message from debugger: Terminated due to memory issue. The code is:

- (void) viewDidAppear:(BOOL)animated {
    self.navigationController.hidesBarsOnSwipe = YES;
}
- (void)didReceiveMemoryWarning {
    // Releases the view if it doesn't have a superview.
    [super didReceiveMemoryWarning];

}

- (void)viewDidUnload {
    [super viewDidUnload];

}
-(void)viewWillAppear:(BOOL)animated {
    [super viewDidLoad];
    self.title = @"Worship Slides";
    [worship loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.316apps.com/Fritch/worship.key"] cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:60.0]];

}

I'm guessing this is old code you've found somewhere. Not that this will solve your problems but…

- (void) viewDidAppear:(BOOL)animated {
    [super viewDidAppear: animated];  // Add super call
    self.navigationController.hidesBarsOnSwipe = YES;
}

// No need for this method if you're not actually overriding it
//- (void)didReceiveMemoryWarning {
//    // Releases the view if it doesn't have a superview.
//    [super didReceiveMemoryWarning];
//
//}

// viewDidUnload was deprecated in iOS 6
//- (void)viewDidUnload {
//    [super viewDidUnload];
//
//}
-(void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated]; // User correct super call here
    self.title = @"Worship Slides";
    [worship loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.316apps.com/Fritch/worship.key"] cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:60.0]];

}

You should not be calling [super viewDidLoad] from the viewWillAppear handler. This could be contributing to your problem, since viewDidLoad is for one-time-init stuff.
