我正在尝试将iOS应用程序移植到OSX,有一件事我没有得到。 iOS应用程序使用UIWebView,更精确的是实现UIWebViewDelegate的UIView:
@interface Dialog : UIView <UIWebViewDelegate> {
并实现这三个委托方法:
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request
navigationType:(UIWebViewNavigationType)navigationType {
- (void)webViewDidFinishLoad:(UIWebView *)webView {
- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error {
有人能给我一个提示,告诉我如何将其移植到普通的OSX框架中吗?我知道有WebView但它有4个代表,据我所知,并且这些代理都没有委托方法听起来像那些。
谢谢

对于第一个,您可能想要使用WebPolicyDelegate。而对于其他两个,WebFrameLoadDelegate中有相应的方法:
- (void)webView:(WebView *)sender didFinishLoadForFrame:(WebFrame *)frame
- (void)webView:(WebView *)sender didFailLoadWithError:(NSError *)error forFrame:(WebFrame *)frame

关于iOS UIWebView
webView:shouldStartLoadWithRequest:navigationType:
,要使用OSX WebView
完成此操作:
为您的WebView实例设置WebPolicyDelegate delegate:
self.webview.policyDelegate = self;
然后在您的委托中实施– webView:decidePolicyForNavigationAction:request:frame:decisionListener:
方法:
-(void)webView:(WebView *)webView
decidePolicyForNavigationAction:(NSDictionary *)actionInformation
request:(NSURLRequest *)request
frame:(WebFrame *)frame
decisionListener:(id < WebPolicyDecisionListener >)listener
{
int actionKey = [[actionInformation objectForKey: WebActionNavigationTypeKey] intValue];
if (actionKey == WebNavigationTypeOther)
{
[listener use];
}
else
{
//
// Here is where you would intercept the user navigating away
// from the current page, and use `[listener ignore];`
//
NSLog(@"\n\nuser navigating from: \n\t%@\nto:\n\t%@",
[webView mainFrameURL],
[[request URL] absoluteString]);
[listener use];
}
}

- (void)webView:(WebView *)webView decisionPolicyForNavigationAction:(NSDictionary *)actionInformation 请求:(NSURLRequest *)请求 frame:(WebFrame *)框架 decisionListener:(id&lt; WebPolicyDecisionListener&gt;)侦听器
我正在使用它而不是shouldStartLoadWithRequest,这很好用
