Question

我是iOS开发的新手，我正在使用具有原生登录屏幕的webview创建应用程序。完成后，我需要关闭webview并返回到本机登录屏幕。我已经看到这个问题得到了解答，但我不明白答案。这是回复的帖子：Close UIWebView using javascript:window.close();

我目前有这个：

NSURL *url = [NSURL URLWithString: @"http://mysite/redirector.php"];
NSString *postData =[[NSString alloc] initWithFormat:@"username=%@&password=%@",[_txtUsername text],[_txtPassword text]];
// Create the request object
NSMutableURLRequest *request = [[NSMutableURLRequest alloc]initWithURL: url];
[request setHTTPMethod: @"POST"];
[request setHTTPBody: [postData dataUsingEncoding: NSUTF8StringEncoding]];

// create the web view
UIWebView *webView = [[UIWebView alloc] initWithFrame:self.view.bounds];
//Change Frame
webView.frame = CGRectMake(webView.frame.origin.x, webView.frame.origin.y + 20,  webView.frame.size.width, webView.frame.size.height);

// Load the request
[webView loadRequest: request];

//show the webview
[self.view addSubview:webView];

我需要在上面的代码中进行哪些更改才能使其工作？

如何“通过[NSURL path]”阅读shouldStartLoadWithRequest:中的模式？

提前致谢。

只需在代码中添加以下内容

即可

NSURL *url = [NSURL URLWithString: @"http://mysite/redirector.php"];
                NSString *postData =[[NSString alloc] initWithFormat:@"username=%@&password=%@",[_txtUsername text],[_txtPassword text]];
                // Create the request object
                NSMutableURLRequest *request = [[NSMutableURLRequest alloc]initWithURL: url];
                [request setHTTPMethod: @"POST"];
                [request setHTTPBody: [postData dataUsingEncoding: NSUTF8StringEncoding]];

                // create the web view
                UIWebView *webView = [[UIWebView alloc] initWithFrame:self.view.bounds];
                //Change Frame
                webView.frame = CGRectMake(webView.frame.origin.x, webView.frame.origin.y + 20, webView.frame.size.width, webView.frame.size.height);

                //assign delegate to webview

                  webView.delegate = self.

                // Load the request
                [webView loadRequest: request];

                //show the webview
                [self.view addSubview:webView];

//并在代理方法

下面实现

  - (void)webViewDidFinishLoad:(UIWebView *)webView{
     [webView removeFromSuperView];
}

//如果要在点击链接时关闭webview，请在代码

下面使用

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

//Webview link press is hyperlink then it will called
    if (navigationType == UIWebViewNavigationTypeLinkClicked){

        [webView removeFromSuperView];
    }

    return YES;

}

从webview返回Native应用程序
