UIWebView使用

例子：

- (void)viewDidLoad
{
    [super viewDidLoad];

    //WebView load   
    //cteate webview
    //动态创建
    _webView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 320, 460)];
    [self.view addSubview:_webView];
    _webView.delegate = self;

    SingleHtmlCollection *theSingleHtml = self.singleHtml;    
    NSString *urlAddress = theSingleHtml.urladdress;     

    NSURL *url = [NSURL URLWithString:urlAddress];
    NSURLRequest *request = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReturnCacheDataElseLoad timeoutInterval:240];
    [_webView loadRequest:request];    
}

在本地实现加载界面：

NSString *aboutPath =
[[NSBundle mainBundle] pathForResource:@"aboutbook" ofType:@"html"];
url = [[NSURL alloc] initFileURLWithPath: aboutPath];

获取当前网页的html的title等信息

例子：

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];

    //get html title and url
    self.singleHtml.urladdress = [_webView stringByEvaluatingJavaScriptFromString:@"document.URL"];
    self.singleHtml.titleName = [_webView stringByEvaluatingJavaScriptFromString:@"document.title"];   
}

在点击WebView中的html链接时，是否跳转

例子：

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

    NSString *strUrl = [request.URL absoluteString];

    if ([strUrl isEqualToString:[_dataController objectInListAtIndex:_intActiveIndex].urladdress]) {
        return YES;
    }else{
        //push new controller
        WebDetailBySYViewController *detailViewController = [[WebDetailBySYViewController alloc] init]; 
        SingleHtmlCollection * aSingleHtml = [[SingleHtmlCollection alloc] init];
        aSingleHtml.urladdress = strUrl;
        aSingleHtml.titleName = [_dataController objectInListAtIndex:_intActiveIndex].titleName;

        detailViewController.singleHtml =  aSingleHtml;
        //detailViewController.bookMarkFlag = YES;        
        detailViewController.hidesBottomBarWhenPushed =  YES;
        [self.navigationController pushViewController:detailViewController animated:YES];
        NSLog(@"nav controller = %@", self.navigationController);
        return NO;
    }

}
