Ios WebView中的随机崩溃
调用堆栈在下面。我有点被难倒了。应用程序会随机崩溃，并使用此调用堆栈。我唯一的线索是它总是在用户处理UIWebView时出现。 这可能是因为我没有消除webview代理，或者正在呈现的页面中的一些视频元素吗？有人见过类似的东西吗？ 谢谢 UIWebView是UIViewController中视图的子视图。 viewDidLoad是webView的初始化位置Ios WebView中的随机崩溃,ios,Ios,调用堆栈在下面。我有点被难倒了。应用程序会随机崩溃，并使用此调用堆栈。我唯一的线索是它总是在用户处理UIWebView时出现。 这可能是因为我没有消除webview代理，或者正在呈现的页面中的一些视频元素吗？有人见过类似的东西吗？ 谢谢 UIWebView是UIViewController中视图的子视图。 viewDidLoad是webView的初始化位置 - (void)viewDidLoad { [super viewDidLoad]; // Do any additi
