Question

我正在使用自定义摄像机。为了方便录制，我将相机设置为纵向叠加，但看起来好像是在风景中。这对我有用，因为我希望视频由于项目的性质而被拉长。目前我正在使用iOS 6来挑战我的视图控制器旋转到纵向，以及当设备旋转到landscapeLeft和landscapeRight时的portraitUpsideDown。无论如何在iOS 6中告诉视图控制器在设备旋转到横向时旋转到纵向？以前我会用shouldAutoRotateToOrientation

来做这件事

目前我正在使用这些方法

- (BOOL)shouldAutorotate {
    return YES;
}

- (NSUInteger)supportedInterfaceOrientationsForWindow {
    return UIInterfaceOrientationMaskPortrait;
}

我已经看过很多关于iOS6中关于这些更改的堆栈溢出的其他文档，但还没有找到解决这个问题的方法。

我们能够开始工作。我们为Landscape做了，但你可以通过修改下面的代码来实现它：

首先在界面中（这只是公司政策的部分b / c，我无法向您展示一切）：

@interface YourViewController : UIViewController <UITableViewDelegate, UITableViewDataSource>
{
    UITableView *myTableView;
    CGAffineTransform _originalTransform;
    CGRect _originalBounds;
    CGPoint _originalCenter;
}

@property (nonatomic, retain) UITableView *myTableView;

@end

接下来是实施：

@implementation YourViewController

@synthesize myTableView;

- (void)loadView {

    UIView *viewContainer = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];

    CGRect tableFrame;
    tableFrame.origin.x += 10;
    tableFrame.origin.y -= 15;
    tableFrame.size.height = 320;
    tableFrame.size.width = 460;

    // create and configure the table view
    myTableView = [[UITableView alloc] initWithFrame:tableFrame style:UITableViewStylePlain];

    myTableView.delegate = self;
    myTableView.dataSource = self;
    myTableView.autoresizesSubviews = YES;
    myTableView.scrollEnabled = YES;    
    myTableView.autoresizingMask = UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleWidth;


    [viewContainer addSubview:myTableView];
    self.view = viewContainer;  
}

- (void)viewWillAppear:(BOOL)animated {

    AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];

    _originalTransform = [[appDelegate navController].view transform];
    _originalBounds = [[appDelegate navController].view bounds];
    _originalCenter = [[appDelegate navController].view center];

    CGAffineTransform landscapeTransform = CGAffineTransformMakeRotation(degreesToRadian(3.14/2));
    //landscapeTransform = CGAffineTransformTranslate (landscapeTransform, +80.0, +100.0);

    [[appDelegate navController].view setTransform:landscapeTransform];

    [appDelegate navController].view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
    [appDelegate navController].view.bounds  = CGRectMake(0.0, 0.0, 480.0, 320.0);
    //[appDelegate navController].view.center  = CGPointMake (240.0, 160.0);

    [UIApplication sharedApplication].statusBarOrientation = UIInterfaceOrientationLandscapeRight;
}

- (void) viewWillDisappear:(BOOL)animated {

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

    [UIApplication sharedApplication].statusBarOrientation = UIInterfaceOrientationPortrait; 
}
