在Leopard的WebView中显示内容时出现问题

我制作了一个示例应用程序,包括:WebView(显示URL的内容)、textfield(包含URL)、button(在WebView中加载URL)。

我使用此方法在WebView中显示内容:

- (IBAction)displayAction:(id)sender{
    NSString *liveStreamLink = [[NSString alloc] initWithString:[livestreamLinkTextField stringValue]];
    [[livestreamDisplayView mainFrame] loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:liveStreamLink]]];
}

我在Leopard和snowleopard中都做了这个应用程序。

https://stackoverflow.com/ 在两个应用程序中都正确打开,但是当我尝试以下链接时- http://www.xyz.com/tools/gauges/livestream.php?data=123456
