failed to return after waiting 10 seconds although getting a BOOL back
提问by Segev
I'm trying to show a fully loaded webview. I don't want the user to see the webview in the loading process. I'm handling a few webviews at a time and using webViewDidFinishLoadmakes it a lot more complex for me so I'm trying to do something like this:
我正在尝试显示一个完全加载的 web 视图。我不希望用户在加载过程中看到 webview。我一次处理几个网络视图，使用webViewDidFinishLoad它对我来说变得更加复杂，所以我正在尝试做这样的事情：
while(_lastWebView.isLoading)
{
_lastWebView.hidden=YES;
}
_lastWebView.hidden=NO;
But I get this msg: void SendDelegateMessage(NSInvocation *): delegate () failed to return after waiting 10 seconds. main run loop mode: kCFRunLoopDefaultMode
但是我得到这个消息：void SendDelegateMessage(NSInvocation *): delegate () 等待 10 秒后未能返回。主运行循环模式：kCFRunLoopDefaultMode
I don't understand why is entering a loop because isLoadingreturns 0 when the loading is finished.
我不明白为什么要进入循环，因为isLoading加载完成后返回 0。

Don't block your UI with that loop. It will stop the user from doing anything else on the main thread.
不要用那个循环阻塞你的 UI。它将阻止用户在主线程上做任何其他事情。
Instead, count the number of requests your webView makes, and make it visible when it's done loading.
