Iphone 纵向应用程序-横向模式视图-无自动旋转

我们的应用程序处于强制肖像模式。没有自动旋转，支持的界面方向设置为仅纵向

现在，我们需要显示一个“签名”视图，它需要处于横向。这应该通过纵向视图进行模式输入，并且需要有导航控制器和导航栏。它应该不能旋转到纵向，并且当模式视图被隐藏时，前一个视图仍应处于纵向

我试过使用：

[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeLeft animated:YES];

但这不会旋转导航栏。。。大概是因为

supportedInterfaceOrientations

需要返回0才能工作

有什么办法可以满足我的需要吗？使用NIB（而不是故事板）

非常感谢

如我所述，您需要允许更多（所有您想要的纵向和横向）模式

原因: 如果应用程序仅支持纵向，则没有ViewController可以支持横向。 如果应用程序同时支持横向和纵向，则所有ViewController都可以定义进一步的限制

在所有ViewController的源代码中，您可以根据具体情况决定是否希望单个ViewController派生为允许纵向或横向。您还可以考虑为所有肖像画等创建一个通用的超级类。

它适用于iPhone

首先，支持的接口方向设置为所有接口 然后

在yourview.h文件中

      AppDelegate *appDel;
 BOOL isShowingLandscapeView;
 CGAffineTransform _originalTransform;
 CGRect _originalBounds;
 CGPoint _originalCenter;
 BOOL isLand,touch;

在yourview.m文件中

    -(void)viewWillAppear:(BOOL)animated
    {
          isLand = NO;

appDel = (AppDelegate*)[[UIApplication sharedApplication] delegate];
[[UIApplication sharedApplication] setStatusBarHidden:TRUE withAnimation:UIStatusBarAnimationNone];
AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
_originalTransform = [[appDelegate navigationController].view transform];
_originalBounds = [[appDelegate navigationController].view bounds];
_originalCenter = [[appDelegate navigationController].view center];

[appDelegate navigationController].view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;

//[appDelegate navigationController].view.bounds  = CGRectMake(0.0,20.0, 480.0, 320.0);
CGSize result = [[UIScreen mainScreen] bounds].size;

if(result.height == 480)
{

    CGAffineTransform landscapeTransform = CGAffineTransformMakeRotation(M_PI/2);
    landscapeTransform = CGAffineTransformTranslate (landscapeTransform, +60.0, +80.0);
    [[appDelegate navigationController].view setTransform:landscapeTransform];

    [appDelegate navigationController].view.bounds  = CGRectMake(-20.0,00.0, 480.0, 320.0);
    [appDelegate navigationController].view.center  = CGPointMake (240.0, 160.0);
}
if(result.height == 568)
{
    CGAffineTransform landscapeTransform = CGAffineTransformMakeRotation(M_PI/2);
    landscapeTransform = CGAffineTransformTranslate (landscapeTransform, +124.0, +124.0);
    [[appDelegate navigationController].view setTransform:landscapeTransform];
    [appDelegate navigationController].view.bounds  = CGRectMake(0.0,0.0, 568, 320.0);
    [appDelegate navigationController].view.center  = CGPointMake (284, 160.0);
}


    }


  -(NSUInteger)supportedInterfaceOrientations
 {
     return UIInterfaceOrientationLandscapeLeft;
 }
  -(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
 {
   AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
  CGSize result = [[UIScreen mainScreen] bounds].size;

  if(result.height == 480)
  {
    [appDelegate navigationController].view.bounds  = CGRectMake(0.0,0.0, 480.0, 320.0);
 }
if(result.height == 568)
{
    [appDelegate navigationController].view.bounds  = CGRectMake(0.0,0.0, 568, 320.0);
}

//    [appDelegate navigationController].view.bounds  = CGRectMake(0.0,0.0, 480.0, 320.0);
 }
     - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
    {
     if(interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight)
    {
       return YES;
    }
   else
   {
      return NO;
   }
   }
  - (void) viewWillDisappear:(BOOL)animated {

   AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
  [[appDelegate navigationController].view setTransform:_originalTransform];
  [[appDelegate navigationController].view setBounds:_originalBounds];
  [[appDelegate navigationController].view setCenter:_originalCenter];

  if (isLand == NO) {
     isLand = YES;

    [UIApplication sharedApplication].statusBarOrientation = UIInterfaceOrientationLandscapeRight;
} else {
    isLand = NO;
     [UIApplication sharedApplication].statusBarOrientation = UIInterfaceOrientationPortrait;
 }


 }

只需执行这些步骤

在目标中进行可能的旋转

在你的应用程序代理（我认为你的应用程序是导航基础）中创建一个UINavigationController类别，如下所示

希望这会有所帮助。

您将演示/推送签名控制器，或者只是将其添加为子视图？您是否仅针对ios 6？@Jennis演示为模式视图否。它也适用于iOS5。应该在IOS 6之前使用AutoRotateTointerFaceOrientation方法。这对我不起作用，你能给我一些关于如何强制旋转的更多信息吗？非常感谢。我们可以聊聊吗？那么我可以更好地帮助你。嗨，这很有效，老实说也很有效。唯一的问题是导航栏-我得到的是更高的纵向导航栏，而不是短的横向导航栏不幸。是否仍有强制它重新绘制导航栏的方法？请尝试此方法[self.navigationController setNavigationBarHidden:YES动画：YES]；请给我一分
