单击UIWebView中的链接将推送到NavigationView堆栈 [英] Clicking a link in UIWebView pushes onto the NavigationView stack

问题描述

基本上，我想知道如何拦截网页浏览中的点击，然后弹出一个新视图，顶部有一个导航栏（带后退按钮），内容是我点击的链接。

Basically, I'd like to know how to intercept a click in a webview and then have a new view pop up that has a navigation bar at the top (with a back button) and the content to be the link I clicked.

我目前有一个带有5个标签的标签栏模板，每个标签当前都设置为NavigationView，每个标签内部都包含一个UIWebView视图。这是我处理链接的方式：

I currently have a tab bar template with 5 tabs and each tab is currently set to NavigationView and inside each of those tabs are views that contain a UIWebView. This is how I handle links:

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

    NSURL *url = request.URL;
    NSString *urlString = url.absoluteString;
    NSRange page = [ urlString rangeOfString: @"/?page=" ];
    // URL is main page
    if ( [ urlString isEqualToString: @"http://somelink-yadayadayada.com/" ] ) {
        return YES;
    }
    // URL contains page number
    else if ( page.location != NSNotFound ) {
        return YES;
    }
    // URL is clicked link
    else {
        // THIS IS WHERE I NEED TO HAVE THE LINK OPEN THE NEW NAV VIEW.
        return NO;
    }
}

如果我需要，我们将非常感谢任何帮助提供更多背景信息我很乐意这样做。谢谢。

Any help would be greatly appreciated and If i need to provide more context I'll be happy to do so. Thanks.

推荐答案

此问题之前已被多次询问过。请查看此页面，它几乎就是您所需要的，只需将 [BrowserViewController openBrowserWithUrl：url]; 更改为将新ViewController推送到导航堆栈所需的任何内容。它可能看起来像这样：

This question has been asked many times before. Please have a look at this page, it's almost exactly what you need, just change the [BrowserViewController openBrowserWithUrl:url]; to whatever you need to push your new ViewController to the navigation stack. It might look like that:

LatestView *latestView = [[LatestView alloc] initWithNibName:@"LatestView" bundle:nil]; 

//Pass the URL here, depends on how you passed it into the WebView in the first place   

// Add the ViewController to the stack
[self.navigationController pushViewController:latestView animated:YES]; 
[latestView release];
