如何在iPhone 3.0操作系统中修复NSURLErrorDomain错误-999 [英] How do I fix NSURLErrorDomain error -999 in iPhone 3.0 OS

问题描述

我正在尝试更新我的iPhone应用程序以使用OS 3.0。我有一个显示页面正常的UIWebView。但是，当我单击一个链接时，它会调用我的委托给didFailLoadWithError，错误是操作无法完成。 （NSURLErrorDomain错误-999。）我确认这仍然适用于OS 2.2.1，所以它在3.0中发生了变化。

I am trying to update my iPhone app to work with OS 3.0. I have a UIWebView that shows a page fine. But when I click a link it calls my delegate for didFailLoadWithError and the error is Operation could not be completed. (NSURLErrorDomain error -999.) I verified this is still working with OS 2.2.1, so it is something changed in 3.0.

任何想法？

推荐答案

我能找到答案这里。

此主题包含此说明对于此错误：如果在完成WebView的上一个请求之前发出另一个请求，则可能会发生此错误...

This thread contained this description for this error: This error may occur if an another request is made before the previous request of WebView is completed...

我通过忽略此错误并让webview继续加载来解决这个问题。

I worked around this by ignoring this error and letting the webview continue to load.

if ([error code] != NSURLErrorCancelled) {
//show error alert, etc.
}
