iOS + UIWebView 实践

1. 调用java script

现在只能实现弹出窗口

[self.m_webView stringByEvaluatingJavaScriptFromString:@"alert(1)"];

2. 获取页面的标签

NSString *title = [self.m_webView stringByEvaluatingJavaScriptFromString:@"document.title"];

3. 页面调用函数

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
 
    if ([request.URL.absoluteString rangeOfString:@"shareMessIOS"].location!=NSNotFound)
    {
        NSString *utf8 = [request.URL.absoluteString stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
        NSArray *array = [utf8 componentsSeparatedByString:@"<|#@VGSEPERATOR@#|>"];
 
        NSString * ss = [array objectAtIndex:1];
        NSLog(@"intro=%@",array );
 
        return NO;
    }
 
    return YES;
}

应该会进来两次，或者以上。第一次不会进入到if ，第二次才进来。
