ios - 如何将 View 从纵向模式旋转到横向模式

Question

我的应用程序中存在方向问题。假设我有两个 View (带有专用 View Controller ):

• first 应该纵向显示(正确显示)
• second 应该横向显示(显示不正确)

它被缩窄并以纵向显示(如下面的第二张图片所示)。当我水平旋转设备并返回纵向时，一切正常。但在推送 View 后，它显示不正确(下图)。我该如何解决这个问题？

我使用 CustomNavigationController whish 继承自 UINavigatorControler 并实现三个方法:

- (NSUInteger)supportedInterfaceOrientations
{
    return [self.topViewController supportedInterfaceOrientations];
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return [self.topViewController preferredInterfaceOrientationForPresentation];
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)orientation
{
    return [self.topViewController shouldAutorotateToInterfaceOrientation:orientation];
}

在应用程序委托(delegate)中，我以这种方式初始化 Controller :

self.navigationController = [[CustomNavigationController alloc] initWithRootViewController:self.viewController];
[self.window setRootViewController:self.navigationController];

第一个 View Controller 以这种方式实现方向功能:

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationPortrait;
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)orientation
{
    if (orientation == UIInterfaceOrientationPortrait)
        return YES;

    return NO;
}

第二个 View Controller 以这种方式实现方向功能:

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscapeRight;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationLandscapeRight;
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)orientation
{
    if (orientation == UIInterfaceOrientationLandscapeRight)
        return YES;

    return NO;
}

Answer 1

hi 声明一个全局变量 BOOL isLandScape ;

initialize it as isLandScape=NO;


   - (NSUInteger)supportedInterfaceOrientations
    {
    return UIInterfaceOrientationMaskLandscapeRight;
  }


-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)orientation
{

  if ((orientation == UIInterfaceOrientationLandscapeRight)||(orientation == UIInterfaceOrientationLandscapeLeft))
{

      isLandScape=YES;

        return YES;

}

else

{

isLandScape=NO;

 return NO;

}

yourObject.frame=CGRectMake(isLandScape?0:0,isLandScape?0:0,isLandScape?1024:768,isLandScape?768:1024);
