我尝试将 AdMob 添加到 Cordova 项目中，因此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，加载时页面底部有更多关于 10px 的空白 block 。 同样的问题也出现在横向 View 中。
这是执行截图。
此问题仅在 webview 调整大小时出现，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，不会出现在 Retina 4 英寸纵向 View 中，也不会出现在 ipad 模拟器中。
这是html代码:

应用初始化
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
我该如何解决这个问题？谢谢!
最佳答案
在html头部使用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 必须为 true 才能启用缩放。
