Ios 如何将视图从纵向模式旋转到横向模式

我的应用程序中的方向有问题。假设我有两个视图（使用专用视图控制器）：

• 首先应以纵向显示（正确显示）
• 秒应以横向显示（未正确显示）

它被压缩并以纵向显示（如下面的第二幅图所示）。 当我水平旋转设备并返回到纵向时，一切正常。但在按下view后，它的显示不正确（下图）。我怎样才能解决这个问题

我使用CustomNavigationController，它继承了UINavigatorController并实现了三种方法：

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

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

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

在application delegate I中，以以下方式初始化控制器：

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

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationPortrait;
}

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

    return NO;
}

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscapeRight;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationLandscapeRight;
}

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

    return NO;
}

第一视图控制器通过以下方式实现方向功能：

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

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationPortrait;
}

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

    return NO;
}

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscapeRight;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationLandscapeRight;
}

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

    return NO;
}

“第二视图控制器”通过以下方式实现方向功能：

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

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationPortrait;
}

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

    return NO;
}

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscapeRight;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationLandscapeRight;
}

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

    return NO;
}

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);


}

为此，您可以使用此功能：

[[UIDevice currentDevice] performSelector:NSSelectorFromString(@"setOrientation:") withObject:(id)UIInterfaceOrientationPortrait];

您可以在任何地方使用它，但在application delegate（在didFinishLaunchingWithOptions中）中，我必须输入以下代码：

[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];

它工作得很好

检查问题并在此处查看答案，以获取您所需的项目示例

基本上，您需要在viewcontroller（要旋转的）中嵌入自定义导航控制器。在此自定义导航控制器中添加以下方法（如果此方法用于横向，但也可以更改为纵向）

并添加到应旋转的视图控制器：

- (BOOL)shouldAutorotate
{
    return YES;
}

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight;
}

确保在项目中启用了纵向、横向右侧和横向左侧方向。然后，如果要阻止特定窗口的某些方向，请执行以下操作：

– application:supportedInterfaceOrientationsForWindow:
