如何在显示UIWebView时防止初始白色闪烁？ [英] How to prevent initial white flash when showing a UIWebView?

问题描述

我使用 UIWebView 通过显示捆绑的HTML文件来显示关于屏幕。我的应用程序的视图层次结构是： UITabBarController / UIViewController / UIWebView 。

I use a UIWebView to show an "About" screen by displaying a bundled HTML file. My app's view hierarchy is: UITabBarController / UIViewController / UIWebView.

问题是，HTML页面有深色背景，第一次轻击标签时，在显示Web视图之前，会短暂显示一个白色背景。我尝试设置 UIWebView 的背景颜色，但这不解决问题。无论是加载 viewDidLoad 或 viewWillAppear 中的内容，都会出现问题。

The problem is that the HTML page has a dark background, and the very first time the tab is tapped, a white background is visible briefly before the web view is displayed. I tried setting the background color of the UIWebView, but that doesn't solve the problem. The problem occurs whether I load the content in viewDidLoad or viewWillAppear.

推荐答案

[webView setOpaque:NO];
webView.backgroundColor = [UIColor clearColor];
