POUIWebView crashing only on second load
text
Body
copied!<p>Ok I've got a dreaded EXC_BAD_ACCESS that I can't seem to track down but it only occurs on my second load of a UIWebView. I've searched and reviewed all the similar issues on SO and tried a few different approaches but I'm still struggling.</p> <p>Here is the program flow that finally loads the WebView.</p> <p>I have a Table View which lists videos. When a row is clicked a Detail View loads, with more info. about the video. Once the detail view is loaded, if the user clicks Play another view loads that has the WebView.</p> <p>In this view, on viewDidLoad the NSURLRequest is created and passed to the WebView loadRequest.</p> <p>The WebView loads fine and displays the webpage with the video I need. All of this is on a navigation controller so the user can click Back and returns to the previous detail view.</p> <p>I am releasing the WebView in the dealloc and also stopping it from loading if it was still doing that. The WebView is obtained via an IBOutlet and is synthesized as (nonatomic,retain).</p> <p>I have NSZombiesEnabled and didn't see any issues there. So when does it crash? If the user clicks Play a second time, the video View is created again and on the [webView loadRequest] - I get a EXC_BAD_ACCESS once the page has loaded.</p> <p>Here is the kicker though, if I go back to the Table and pick another row (video), then I can load that WebView without any problems. It is only if I load the same video twice that it crashes.</p> <p>The view that holds the WebView is released after being created and pushed on the nav. controller. I setup a ton of break points - everything (on the second load) is good right up until the webViewDidFinishLoad is called, whatever happens after that is causing the crash. I don't get a stack trace (or don't know how to find it) :)</p> <p>Thanks!</p> <p>Here is the code from the WebView view - some of this was based on other peoples findings of memory issues with UIWebView.</p> <pre><code> - (void)viewDidLoad { [super viewDidLoad]; self.title = @"Video Player"; NSURL *url = [NSURL URLWithString:video.url]; NSURLRequest *request = [NSURLRequest requestWithURL:url]; [webView loadRequest:request]; } - (void)viewDidUnload { [super viewDidUnload]; [webView setDelegate:nil]; [self setWebView:nil]; } - (void)dealloc { [video release]; [super dealloc]; } </code></pre>
