Question

通常，当您点击网络浏览器上的“使用Facebook注册”按钮时，将弹出一个新选项卡。但是当你尝试在WebView上做同样的事情时，它不会做任何事情，它会停留在同一个网站上。如何强制WebView显示对话框？

Answer 1

在您的代理中实施-webView:decidePolicyForNewWindowAction:request:newFrameName:decisionListener:。如果你还没有，你可能还需要实现至少一些WebUIDelegate协议方法。

参考：WebPolicyDelegate Protocol Reference，WebUIDelegate Protocol Reference

Answer 2

这是你可能正在寻找的东西。将它放在AppDelegate.m中，然后所有外部链接将在默认浏览器中打开：

// Habilita links externos abrirem no navegador padrão
- (WebView *)webView:(WebView *)sender createWebViewWithRequest:(NSURLRequest *)request
{
    // HACK: This is all a hack to get around a bug/misfeature in Tiger's WebKit
    // (should be fixed in Leopard). On Javascript window.open, Tiger sends a null
    // request here, then sends a loadRequest: to the new WebView, which will
    // include a decidePolicyForNavigation (which is where we'll open our
    // external window). In Leopard, we should be getting the request here from
    // the start, and we should just be able to create a new window.

    WebView *newWebView = [[WebView alloc] init];
    //[newWebView setUIDelegate:self];
    [newWebView setPolicyDelegate:self];

    return newWebView;
}

- (void)webView:(WebView *)sender decidePolicyForNavigationAction:(NSDictionary *)actionInformation request:(NSURLRequest *)request frame:(WebFrame *)frame decisionListener:(id<WebPolicyDecisionListener>)listener {
    if( [sender isEqual:myWebView] ) {
        [listener use];
    }
    else {
        [[NSWorkspace sharedWorkspace] openURL:[actionInformation objectForKey:WebActionOriginalURLKey]];
        [listener ignore];
        //[sender release];
    }
}

- (void)webView:(WebView *)sender decidePolicyForNewWindowAction:(NSDictionary *)actionInformation request:(NSURLRequest *)request newFrameName:(NSString *)frameName decisionListener:(id<WebPolicyDecisionListener>)listener {
    [[NSWorkspace sharedWorkspace] openURL:[actionInformation objectForKey:WebActionOriginalURLKey]];
    [listener ignore];
}
// -

（sim，eu sou br！）
