UIWebView崩潰加載鏈接從HTML

如果我在包含外部鏈接的UIWebView中調用loadHTMLString，然後嘗試重新加載HTMLString它崩潰。UIWebView崩潰加載鏈接從HTML

HTML載入如下：

NSURL *url = [[NSBundle mainBundle] URLForResource:@"help" withExtension:@"html"]; 
    NSString *text = [NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:nil]; 

    [[self webView] loadHTMLString:text baseURL:nil];

help.html可以包含一個鏈接，如：

Example

如果我點擊它加載頁面的鏈接。但是我在導航欄上有一個「Home」按鈕，它再次調用上面的代碼（loadHTMLString），這會使應用程序崩潰。

任何方式來「欺騙」UIWebView在外部鏈接被查看後再次加載HTML字符串？

其他測試表明，該問題與jQuery手機有關。如果我用鏈接使用簡單的HTML文件，它不會崩潰。我計劃明天再追查一次。 – Christopher 2013-05-14 07:26:30

以及它似乎是在UIWebview.The UIWebView的錯誤是不應該崩潰，即使TEH內容不存在或HTML錯誤occours.File錯誤

是的，我認爲這是一個錯誤，因爲我可以每次重現它。 – Christopher 2013-05-14 07:00:03
