隐藏 uitabbar 时视图上的空白区域
我知道还有其他关于此问题的帖子，但它们似乎对我不起作用。当我的应用程序中的 uinavigationcontroller 推送特定视图时，我将视图旋转到横向模式并隐藏选项卡栏。但是，当选项卡栏隐藏而不是显示其后面的视图时，会显示空白区域。
为了解决此问题，我在 viewDidLoad 方法中使用了以下代码行，正如有关此问题的其他帖子所建议的那样，但并没有解决问题。
[self.view setFrame:CGRectMake(0.0f, 0.0f, 320.0f, 480.0f)];
如果有人知道发生了什么事，请帮忙。 谢谢，
I know there are other posts about this issue, but they don't seem to work for me. When a particular view is pushed by my uinavigationcontroller in my app, I rotate the view to landscape mode and hide the tabbar. however, when the tabbar hides instead of displaying the view behind it displays a blank white space.
To solve this I used the following line of code in my viewDidLoad method as suggested by other posts about this issue, but it didn't solve it.
[self.view setFrame:CGRectMake(0.0f, 0.0f, 320.0f, 480.0f)];
If anyone knows what's going on, please help.
Thanks,

您应该在视图中（无论是笔尖还是代码）将
setAutoresizingMask:设置为UIViewAutoresizingFlexibleHeight或UIViewAutoresizingFlexibleBottomMargin（不确定哪一个）做这个伎俩。如果这不能解决您的问题，我猜您使用setHidden:隐藏选项卡栏。尝试调用此方法。You should set
setAutoresizingMask:in your view (whether in nib or code) toUIViewAutoresizingFlexibleHeightorUIViewAutoresizingFlexibleBottomMargin(don't sure which one) that should do the trick. In case this donesn't solved your problem I guess that you hide the tabbar by usingsetHidden:. Try calling this instead.如果您的视图大小合适，请尝试调用 [self.view setNeedsDisplay]。当你改变大小时它应该做类似的事情，所以我不确定。
If your view is the right size then try calling [self.view setNeedsDisplay]. It should do something similar when you change the size though so I'm not sure.
