用本地“加载”填充 UIWebView互联网内容之前的图像

发布于 2024-11-27 02:52:49 字数 214 浏览 1 评论 0原文

我有一个 UITableView ，其标题作为 uiwebview (320*44px) 用于发布内容。我想知道如何在从网络加载内容之前显示一些本地内容图像或背景颜色或其他内容？

（目标：消除未加载的 uiwebview 横幅的白色默认背景）

UIImageView *imageView=[[UIImageView alloc]initWithFrame:webView.bounds];

[imageView setImage:[UIImage imageNamed:@"vijay.png"]];//image size should ur specification 320*44px

[imageView setTag:55];


[webView addSubview:imageView];

[imageView release];

    [[webView viewWithTag:55] removeFromSuperview];
