我正在使用：

 if (UIInterfaceOrientationLandscapeLeft | UIInterfaceOrientationLandscapeRight)
{
    viewofimage.frame = CGRectMake(130, 45, 220, 115);
    share.frame = CGRectMake(205, 161, 70, 70);
    invite.frame = CGRectMake(8, 161, 70, 70);
    contact.frame = CGRectMake(402, 161, 70, 70);
    invitation.frame = CGRectMake(3, 227, 81, 21);
    sharing.frame = CGRectMake(200, 227, 81, 21);
    contacting.frame = CGRectMake(397, 227, 81, 21);
}
else
{
    viewofimage.frame = CGRectMake(20, 64, 280, 206);
    invite.frame = CGRectMake(8, 285, 70, 70);
    share.frame = CGRectMake(125, 285, 70, 70);
    contact.frame = CGRectMake(242, 285, 70, 70);
    invitation.frame = CGRectMake(3, 358, 81, 21);
    sharing.frame = CGRectMake(120, 358, 81, 21);
    contacting.frame = CGRectMake(237, 358, 81, 21);
}

旋转时在特定位置设置按钮和标签。唯一的问题是，当我离开该视图控制器并转到另一个控制器时，使用相同的代码，它不会将按钮和标签移动到定义的 CGRECTMAKE 值。它仅在选定的视图控制器旋转时移动它们。如何让其他视图控制器检测它所处的方向，并在到达它们时正确调整其大小？

【解决方案1】：

设置 UIView 的 autoMaskSubView 为 false 使用这种方法：

 - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation{

if (interfaceOrientation = UIInterfaceOrientationLandscapeLeft || interfaceOrientation = UIInterfaceOrientationLandscapeRight)
{
viewofimage.frame = CGRectMake(130, 45, 220, 115);
share.frame = CGRectMake(205, 161, 70, 70);
invite.frame = CGRectMake(8, 161, 70, 70);
contact.frame = CGRectMake(402, 161, 70, 70);
invitation.frame = CGRectMake(3, 227, 81, 21);
sharing.frame = CGRectMake(200, 227, 81, 21);
contacting.frame = CGRectMake(397, 227, 81, 21);
}
else
{
viewofimage.frame = CGRectMake(20, 64, 280, 206);
invite.frame = CGRectMake(8, 285, 70, 70);
share.frame = CGRectMake(125, 285, 70, 70);
contact.frame = CGRectMake(242, 285, 70, 70);
invitation.frame = CGRectMake(3, 358, 81, 21);
sharing.frame = CGRectMake(120, 358, 81, 21);
contacting.frame = CGRectMake(237, 358, 81, 21);
}

return YES; 
}

这是有效的，但我遇到了一个问题。每个选项卡都是一个导航控制器，我将导航栏设置为隐藏。一些按钮推动了一个带有自己的 xib 的表格视图，需要有导航栏，所以当这些按钮出现时，我取消隐藏导航栏。这会导致 UIButtons 向下滑动导航栏的高度，而不是 ImageView。关于如何防止这种情况发生的任何想法？

View Controller 每次检测到旋转时都会调用此方法。我认为这就是您目前拥有此代码的地方

-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
    if (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft || toInterfaceOrientation == UIInterfaceOrientationLandscapeRight)
    {
        viewofimage.frame = CGRectMake(130, 45, 220, 115);
        share.frame = CGRectMake(205, 161, 70, 70);
        invite.frame = CGRectMake(8, 161, 70, 70);
        contact.frame = CGRectMake(402, 161, 70, 70);
        invitation.frame = CGRectMake(3, 227, 81, 21);
        sharing.frame = CGRectMake(200, 227, 81, 21);
        contacting.frame = CGRectMake(397, 227, 81, 21);
    }
    else
    {
        viewofimage.frame = CGRectMake(20, 64, 280, 206);
        invite.frame = CGRectMake(8, 285, 70, 70);
        share.frame = CGRectMake(125, 285, 70, 70);
        contact.frame = CGRectMake(242, 285, 70, 70);
        invitation.frame = CGRectMake(3, 358, 81, 21);
        sharing.frame = CGRectMake(120, 358, 81, 21);
        contacting.frame = CGRectMake(237, 358, 81, 21);
    }
}

如果您想在移动到不同的 viewController 时检测方向并相应地放置对象...那么您可以像这样检测您所处的方向：

-(void)viewWillAppear:(BOOL)animated
{
    UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];
    if (orientation == UIInterfaceOrientationLandscapeLeft || orientation == UIInterfaceOrientationLandscapeRight)
    {
        viewofimage.frame = CGRectMake(130, 45, 220, 115);
        share.frame = CGRectMake(205, 161, 70, 70);
        invite.frame = CGRectMake(8, 161, 70, 70);
        contact.frame = CGRectMake(402, 161, 70, 70);
        invitation.frame = CGRectMake(3, 227, 81, 21);
        sharing.frame = CGRectMake(200, 227, 81, 21);
        contacting.frame = CGRectMake(397, 227, 81, 21);
    }
    else
    {
        viewofimage.frame = CGRectMake(20, 64, 280, 206);
        invite.frame = CGRectMake(8, 285, 70, 70);
        share.frame = CGRectMake(125, 285, 70, 70);
        contact.frame = CGRectMake(242, 285, 70, 70);
        invitation.frame = CGRectMake(3, 358, 81, 21);
        sharing.frame = CGRectMake(120, 358, 81, 21);
        contacting.frame = CGRectMake(237, 358, 81, 21);
    }
}
