如何在 iPhone 的横向模式下正确调整 webview 的大小？

我添加一个导航栏、一个网络视图和一个工具栏（从上到下）作为视图控制器视图的子视图。我希望导航栏和工具栏的高度在横向方向上稍微缩小一些，因此我使用 autoresizingmask 来使高度灵活。（UIViewAutoresizingFlexibleHeight会让navigationbar和toolbar的高度从44缩小到30左右）：

webNavBar.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleBottomMargin;
webToolBar.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleTopMargin;
webView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;

现在我发现当我将设备旋转到横向模式时，webview的顶部和底部会出现两个空白的白色条（每个空白条的高度为44-30）。导航栏和工具栏似乎位于正确的位置。有什么方法可以调整网络视图的大小并填补空白吗？

I add a navigationbar, a webview and a toolbar(from top to bottom) as subviews of my viewcontroller's view. I want the navigationbar and toolbar's height shrink a little in landscape orientation so I use autoresizingmask to make the height flexible. (UIViewAutoresizingFlexibleHeight will make navigationbar and toolbar's height shrink from 44 to around 30):

webNavBar.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleBottomMargin;
webToolBar.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleTopMargin;
webView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;

Now I found that when I rotate the device to landscape mode, there will be two blank white bars on the top and bottom of the webview(each blank bar's height is 44-30). Navigationbar and toolbar appear to be in the correct position. Is there any way to resize the webview and fill the gaps?

您确定 Web 视图的自动调整边距设置正确吗？总是可以做：

-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
   webView.frame = self.view.frame;
}

不知道这是否有效，但值得一试。

Are you sure the Autoresizing margins are set correctly for the webview? could always do:

-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
   webView.frame = self.view.frame;
}

No idea if that will work but worth a shot.

检查此链接。
UIWebView 在将方向更改为景观

这对我有用：-
将以下代码添加到具有 webView 的控制器中：-

 (void)willAnimateRotationToInterfaceOrientation: (UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration  
 {
     [self.myWebView setFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
 }

Check this link.
UIWebView not re-sizing after changing orientation to landscape

This worked for me: -
Add the following code to the controller which has the webView: -

 (void)willAnimateRotationToInterfaceOrientation: (UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration  
 {
     [self.myWebView setFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
 }
