我无法显示网络视图。我在自定义视图中有一个webview。我将此自定义视图加载为窗口的子视图，然后让一个对象控制器将文本字段链接到Web视图的内容。加载页面后，它将加载所有内容，但外观为白色。您可以单击链接。如果您观看Youtube视频，则可以收听，但仍不显示任何内容。 要加载自定义视图，请运行：

I am having trouble displaying a webview. I have a webview inside a custom view. I load this custom view as a subview of the window, and then have an object controller linking a text field to the content of the web view. Once a page is loaded, it loads all the content, but it is visually white. You can click on links. If you go to a Youtube video you can listen to it, but it still displays nothing. To load the custom view I run:

PageViewController *page = [[PageViewController alloc] initWithNibName:@"PageView" bundle:nil]; [page loadView]; [view addSubview:[page view]];

然后要加载页面，我有以下内容：

Then to load the page I have the following:

-(IBAction)connectURL:(id)sender { NSLog(@"connecting"); [webView setMainFrameURL:[sender stringValue]]; }

connectURL绑定到文本字段的位置。

Where connectURL is bound to a text field.

推荐答案

您是否已将自定义视图设置为分层支持？您不能在层支持的视图中使用 WebView 。如果不是问题，可以张贴自定义视图的绘图代码吗？

Have you set your custom view to be layer-backed? You can't use a WebView in a layer-backed view. If that's not the problem, can you post your custom view's drawing code?
