推荐答案

我刚刚碰到这个问题，并以这种方式解决：

I just ran into this problem myself, and solved it this way:

我的主控制器对象被设置为WebView的policyDelegate。

My main controller object was set as the policyDelegate for the WebView.

然后实现这个方法：

- (void)webView:(WebView *)webView 
    decidePolicyForNavigationAction:(NSDictionary *)actionInformation
    request:(NSURLRequest *)request frame:(WebFrame *)frame 
    decisionListener:(id < WebPolicyDecisionListener >)listener
{
    NSString *host = [[request URL] host];
    if (host) {
        [[NSWorkspace sharedWorkspace] openURL:[request URL]];
    } else {
        [listener use];
    }
}

我需要检查主机，因为否则当我加载WebView的初始内容（在我的项目中只是一个静态html页面），它是在Safari中启动。现在，只有与实际主机的链接（外部链接）被发送到Safari，这是我想要的行为。我想我也可以没有设置policyDelegate，直到加载初始页面。

I needed to have the check for the host there, because otherwise when I load the initial content of the WebView (just a static html page in my project), it was being launched in Safari. Now, just links with actual hosts (external links) get sent to Safari, which is the behavior I wanted. I think I could also have not set the policyDelegate until after the initial page was loaded.
