如何检测 UIWebView 中的点击事件 [英] How to detect a click event in a UIWebView

问题描述

我有一个 UITableView，它可以像这样将内容加载到 UIWebView 中:

I have a UITableView that loads content into a UIWebView like this:

//MainViewController.m
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
      CGRect bounds = [ [ UIScreen mainScreen ] applicationFrame ];
      UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:bounds];
      UIWebView *htmlView = [ [ UIWebView alloc ] initWithFrame:[scrollView bounds]];
htmlView.frame = CGRectMake(10,10,280,360);
      NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];

    //Load the request in the UIWebView.
    [htmlView loadRequest:requestObj];

    scrollView.contentSize = [htmlView bounds].size;
    [scrollView addSubview:htmlView];    
    [detailsViewController.view addSubview:htmlView];


    [htmlView release];
    htmlView = nil;

    [scrollView release];
    scrollView = nil;


   [[self navigationController] pushViewController:detailsViewController animated:YES];
   [detailsViewController release];

}

提供给 UIWebView 的所有远程内容都来自我编写的 Web 服务.第一个屏幕截图是从标题为词汇表"的列表视图中选择一个单词时显示的内容

All of the remote content that gets fed to the UIWebView comes from a web service that I wrote. The first screenshot is what is presented when a word is selected from the list view titled "Glossary"

这一切都很好，直到您点击链接，在这种情况下，点击 UIWebView 内容中的框架"链接.新内容已加载，但我需要告诉导航栏 UIWebView 已更改，因此我至少可以更改白色标题文本以匹配新内容.我应该实现哪些 UIWebView 方法以及它们应该去哪里?

This all is great until you follow a link, in this case clicking on the "frame" link in the UIWebView content. The new content gets loaded but I need to tell the nav bar that the UIWebView has changed so I can at least change the white title text to match the new content. What UIWebView methods should I implement and where should they go?

推荐答案

将你的view controller设置为UIWebView的delegate，然后实现

Set your view controller to be the UIWebView's delegate, then implement

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