我试图将 AdMob 添加到 Cordova 项目中，所以我在应用加载时修改了 webview 大小。

- (void)viewWillAppear:(BOOL)animated
{
    // View defaults to full size.  If you want to customize the view's size, or its subviews (e.g. webView),
    // you can do so here.

    /*add admob*/
    CGSize sizeOfScreen = [[UIScreen mainScreen] bounds].size;
    CGSize sizeOfView = self.view.bounds.size;
    CGRect statusBarFrame = [[UIApplication sharedApplication] statusBarFrame];

    if  (UIInterfaceOrientationIsLandscape(self.interfaceOrientation))
    {
        //landscape view code
        CGPoint origin = CGPointMake(0, sizeOfScreen.width - CGSizeFromGADAdSize(kGADAdSizeSmartBannerLandscape).height-statusBarFrame.size.width);
        bannerView_ = [[[GADBannerView alloc]initWithAdSize:kGADAdSizeSmartBannerLandscape origin:origin] autorelease];
    }else{
        //portrait view code
        CGPoint origin = CGPointMake(0, sizeOfScreen.height - CGSizeFromGADAdSize(kGADAdSizeSmartBannerPortrait).height-statusBarFrame.size.height);
        bannerView_ = [[[GADBannerView alloc]initWithAdSize:kGADAdSizeSmartBannerPortrait origin:origin] autorelease];
    }

    bannerView_.adUnitID = MY_BANNER_UNIT_ID;
    bannerView_.rootViewController = self;
    [self.view addSubview:bannerView_];
    GADRequest *request = [GADRequest request];

    request.testing = YES;
    [bannerView_ loadRequest:request];

    /*resize webview*/
    CGRect webViewFrame = [ [ UIScreen mainScreen ] applicationFrame ];
    CGRect windowFrame = [ [ UIScreen mainScreen ] bounds ];

    webViewFrame.origin = windowFrame.origin;

    if  (UIInterfaceOrientationIsLandscape(self.interfaceOrientation)){
        webViewFrame.size.height = sizeOfScreen.width-CGSizeFromGADAdSize(kGADAdSizeSmartBannerLandscape).height-statusBarFrame.size.width;
        webViewFrame.size.width = sizeOfScreen.height;

    }else{
        webViewFrame.size.height = windowFrame.size.height-CGSizeFromGADAdSize(kGADAdSizeSmartBannerPortrait).height-statusBarFrame.size.height;
        webViewFrame.size.width = sizeOfScreen.width;
    }

    self.webView.frame = webViewFrame;

    [super viewWillAppear:animated];
}

现在 webview 的大小应该是 320X410。但是，加载时页面底部会有更多大约 10px 的空白块。同样的问题也出现在横向视图中。

这是执行截图。 这是执行截图

仅当 webview 调整大小时才会出现此问题，并且内容超出屏幕没有问题。此问题将出现在 iphone 5.0 5.1 6.0 模拟器中，而不会出现在 Retina 4 英寸纵向视图中，也不会出现在 ipad 模拟器中。

这是html代码：

<!DOCTYPE html> 
<html>

<head>
    <meta charset="utf-8">
    <title>Single page template</title>
    <link rel="stylesheet" href="http://code.jquery.com/mobile/1.3.0-beta.1/jquery.mobile-1.3.0-beta.1.min.css" />
    <script src="http://code.jquery.com/jquery-1.8.2.min.js"></script>
    <script src="http://code.jquery.com/mobile/1.3.0-beta.1/jquery.mobile-1.3.0-beta.1.min.js"></script>
</head>
<script type="text/javascript">
  $(document).ready(function() {
    alert($(window).height());
    alert($(document).height());
    alert($("body").height());
  });
</script> 
<body> 

<div data-role="page">

    <div data-role="header">
        <h1>Single page</h1>
    </div><!-- /header -->

    <div data-role="content">   
        <p>This is a single page boilerplate template that you can copy to build your first jQuery Mobile page. Each link or form from here will pull a new page in via Ajax to support the animated page transitions.</p>      
    </div><!-- /content -->

</div><!-- /page -->

</body>
</html>

配置文件

<preference name="KeyboardDisplayRequiresUserAction" value="true" />
<preference name="SuppressesIncrementalRendering" value="false" />
<preference name="UIWebViewBounce" value="false" />
<preference name="TopActivityIndicator" value="gray" />
<preference name="EnableLocation" value="false" />
<preference name="EnableViewportScale" value="false" />
<preference name="AutoHideSplashScreen" value="true" />
<preference name="ShowSplashScreenSpinner" value="false" />
<preference name="MediaPlaybackRequiresUserAction" value="false" />
<preference name="AllowInlineMediaPlayback" value="false" />
<preference name="OpenAllWhitelistURLsInWebView" value="false" />
<preference name="BackupWebStorage" value="cloud" />

应用程序初始化

self.window = [[[UIWindow alloc] initWithFrame:screenBounds] autorelease];
self.window.autoresizesSubviews = YES;
self.viewController = [[[MainViewController alloc] init] autorelease];
self.viewController.useSplashScreen = NO;
self.viewController.wwwFolderName = @"www";
self.viewController.startPage = @"index.html";

Cordova 2.3.0 Xcode 4.5.2 jQuery Mobile 1.3.0 beta1, 1.2.0

我应该如何解决这个问题？谢谢！

在 html 头中使用 viewport 标签

<meta name="viewport" content="user-scalable=yes, initial-scale=1, maximum-scale=1, minimum-scale=1, width=device-width, height=device-height, target-densityDpi=device-dpi" />

还要确保EnableViewportScale桅杆是true启用规模。

提出这个问题的原因是jquery-mobile限制了屏幕的最小高度。纵向屏幕min-height为 420px，横向屏幕min-height为 300px。当webview高度修改为410px时，底部多了10px左右的空白块。

jquery.mobile-1.2.0.min.css

media screen and (orientation: portrait){
  .ui-mobile, .ui-mobile .ui-page {
    min-height: 420px;
  }
}
media screen and (orientation: landscape){
  .ui-mobile, .ui-mobile .ui-page {
    min-height: 300px;
  }
}

覆盖或删除 css 规则可以解决此问题。

<html style="min-height:0px">

或者

html{
  min-height: 0px !important; 
}
