Run youtube on webView crash sometimes

Question

I build sample app that load youtube in webview, sometimes in specific videos the app is crash. This is the log:

This application is modifying the autolayout engine from a background thread, which can lead to engine corruption and weird crashes. This will cause an exception in a future release.

I know that this is main thread issue when player start play the video, but not have solution, another thing that maybe can help to solve this, when this is happened, the webview delegate methud -shouldStartLoadWithRequest not called...

This is my viewWillApear :

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];

    _ytWebView.delegate = self;
    _ytWebView.allowsLinkPreview = YES; 
    NSURL *url = [NSURL URLWithString:@"https://www.youtube.com"];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];

    [_ytWebView loadRequest:request];

}

Any help would be appreciated.

Try running it on the main thread instead:

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];

    _ytWebView.delegate = self;
    _ytWebView.allowsLinkPreview = YES; 
    NSURL *url = [NSURL URLWithString:@"https://www.youtube.com"];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
dispatch_async(dispatch_get_main_queue(), ^{
    [_ytWebView loadRequest:request];
});
}

and this is still crash : ( – Yakir Sayada Jun 30 '16 at 12:43
Hey wait, why are you calling this in `viewWillAppear`? That's where you're going wrong. Call it in `viewDidLoad`. With `dispatch_async`. I think it should work. I'll update my answer if you confirm this works. – Mtoklitz113 Jun 30 '16 at 12:50
The crash still happened – Yakir Sayada Jun 30 '16 at 12:52
Did you load it in `viewDidLoad`? – Mtoklitz113 Jun 30 '16 at 13:03
Try `__weak typeof(self) weakSelf = self;` in your code and use it in `dispatch_async` block. – Mtoklitz113 Jun 30 '16 at 15:16
I dont understand where and when to use weakSelf parameter. – Yakir Sayada Jul 04 '16 at 08:05
