Clicking weird error: "DOMException 105" in an iOS application. Looking for a guide on how to find an error in my code

Question

Cannot find a link to this error - anywhere!

This happens at the same point every time - just like I click on a UITableView row element. Below is a stack trace - can anyone give any suggestions as to what might be the problem and / or how to find the error?

Thanks!

Answer 1

I had the same problem as finding a solution from the last two days. Finally, today I found a solution, either you need to add self.view.isAccessibilityElement = true to viewDidLoad , or set the Attribute property of the view in the interface, as shown below.

Answer 2

I had the same issue when VoiceOver turned on when loading webview. It seemed to be linking to content in a web browser before it was fully downloaded. To stop this crash, I simply hid the accessibility elements until the webview was loaded. Be sure to set the ViewController as a UIWebViewDelegate . Then:

ObjC example:

 -(void)viewDidLoad { [super viewDidLoad]; [self.view setAccessibilityElementsHidden:YES]; } -(void)webViewDidFinishLoad:(UIWebView*)webView { [self.view setAccessibilityElementsHidden:NO]; } 

Swift example: (You must use WKWebView, so I will give you an example of this below). Be sure to set the ViewController as WKNavigationDelegate

 override func viewDidLoad() { super.viewDidLoad() view.accessibilityElementsHidden = true } func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) { view.accessibilityElementsHidden = false } 

Hope this helps.
