UIWebView解决加载页面时背景一片空白问题_html/css_WEB-ITnose

webView.backgroundColor = [UIColor clearColor];webView.opaque = NO;[webView setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"webbg.png"]]];

    self.webView=[[[UIWebView alloc]initWithFrame:self.view.bounds]autorelease];    [self.webView loadRequest:request];    [self.view addSubview:self.webView];        UIImageView *imageView = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"gatewaybg.png"]];    imageView.frame = CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, [UIScreen mainScreen].bounds.size.height);    [self.view addSubview:imageView];

- (void)webViewDidFinishLoad:(UIWebView *)webView{    // WebView放到最上层    [self.view bringSubviewToFront:self.webView];    // 或者可以把背景图移除    [self.webView removeFromSuperview];}
