无法在 iOS 中更改 UIWebView 的背景

问题描述

有没有办法改变 UIWebView 的背景颜色?

Is there a way to change background color for UIWebView?

IB 中设置的所有颜色均未影响 UIWebView 行为:在加载实际内容之前，它显示为白色(在加载和呈现内容之间导致白色闪烁).

None of the colors set in IB effect UIWebView behavior: before actual content is loaded it shows as up as white (causing a white flash between the moment it is loaded and content is rendered).

以编程方式设置背景颜色也不做任何事情.

Setting background color programmatically does not do anything either.

代码如下:

@interface Web_ViewViewController : UIViewController {

    UIWebView *web;
}

@property (nonatomic, retain) IBOutlet UIWebView *web;
@end

....
-(void)viewDidLoad {
    super viewDidLoad;

    web.backgroundColor = [UIColor blueColor];
    NSURL *clUrl = [NSURL URLWithString:@"http://www.apple.com"];
    NSURLRequest *req = [NSURLRequest requestWithURL:clUrl];

    [web loadRequest:req];
}

推荐答案

可以将webview的opaque属性设置为NO，然后设置下view的背景色.

You can set the opaque property of the webview to NO and then set background color of the view beneath.

[webView setOpaque:NO];
