[self.webView loadRequest：[NSURLRequest requestWithURL：[NSURL URLWithString：@“about：blank”]]];在每个页面加载到应用程序之前，他们希望显示一个空白屏幕以向用户显示应用程序是否响应。因此插入了一个空白页面。一旦我删除它，它修复了前述的崩溃。 – user1208489 2012-02-14 14:33:35

检查您在NSDictionary中添加数据的位置。可能是那个地方插入了空值。

对于其他人有这个问题，如果你无处有意加载空白页，你可以尝试添加这网页视图：shouldStartLoadWithRequest：

if (request == nil) { 
    return NO; 
}
