遇到奇怪的错误:"DOMException 105"在IOS应用中.寻找有关如何在我的代码中找到错误的指导 [英] Hitting strange error: "DOMException 105" in IOS app. Looking for guidance on how to locate the bug in my code

问题描述

在任何地方都找不到此错误的引用！

Having trouble finding any reference to this error - anywhere!

每次都在同一时间发生-就像我单击UITableView行元素一样.下面是堆栈跟踪-有人可以提供有关问题可能是什么和/或如何查找错误的任何建议吗?

It happens at the same point every time - just as I click on a UITableView row element. Below is the stack trace - can someone provide any suggestions as to what the problem might be and/or how to go about finding the bug?

谢谢！

推荐答案

在加载Web视图时启用VoiceOver时，我遇到了同样的问题.看起来好像是在完全加载之前引用了Webview中的内容.为了阻止此崩溃的发生，我只是隐藏了可访问性元素，直到加载Webview之后.确保将ViewController设置为 UIWebViewDelegate .然后:

I had the same issue when VoiceOver was on while loading a webview. It seemed like it was referencing the content in the webview before it was fully loaded. To stop this crash from happening, I simply hid the accessibility elements until after the webview was loaded. Be sure to set the ViewController as the UIWebViewDelegate. Then:

ObjC示例:

-(void)viewDidLoad {
   [super viewDidLoad];

   [self.view setAccessibilityElementsHidden:YES];
}

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

快速示例:(您应该使用WKWebView，所以下面为您提供示例).确保将ViewController设置为 WKNavigationDelegate

Swift example: (You should be using WKWebView so I'll give you an example of that 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
}

希望有帮助.
