objective-c - 使用委托(delegate)以编程方式创建 UIWebView

Question

我正在以编程方式创建 UIWebView，但我需要触发此函数，以便在自定义 View 中打开 href:

-(bool) webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{

    //You might need to set up a interceptLinks-Bool since you don't want to intercept the initial loading of the content
    if (interceptLinks) {
        NSURL *url = request.URL;
        //This launches your custom ViewController, replace it with your initialization-code
        BrowserViewController *bv = [[BrowserViewController alloc] initWithUrl:url];
        bv.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
        [self presentModalViewController:bv animated:YES];
        [bv release];
         return NO;
    }
    //No need to intercept the initial request to fill the WebView
    else {
        interceptLinks = YES;
        return YES;
    }
}

如何将委托(delegate)链接到以编程方式创建的 UIWebView 以便函数触发？

Answer 1

您在上面所做的看起来是正确的。

只需在接口(interface)类和实现类上添加 UIWebViewDelegate 协议(protocol)
添加

webview.delegate = self;

所以你的 shouldStartLoadWithRequest 被调用。
