@property (strong,nonatomic)UIWebView *webView;
@property (strong,nonatomic)NSString *currentURL;
@property (strong,nonatomic)NSString *currentTitle;
@property (strong,nonatomic)NSString *currentHTML;

-(void) webViewDidFinishLoad:(UIWebView *)webView {
[UIApplicationsharedApplication].networkActivityIndicatorVisible =NO;
self.title ＝ [webViewstringByEvaluatingJavaScriptFromString:@"document.title"];//获取当前页面的title

self.currentURL = webView.request.URL.absoluteString;
NSLog(@"title-%@--url-%@--",self.title,self.currentURL);

NSString *lJs = @"document.documentElement.innerHTML";//获取当前网页的html

self.currentHTML = [webView stringByEvaluatingJavaScriptFromString:lJs];
