Iphone 横向显示视图

我正在显示一个视频，我需要旋转视图，使其以横向方向显示。我写了下面的代码，它完全符合我的要求。问题是，当我单击后退按钮时，（显示载体标题和时间的栏）仍然是横向的（对于假定为纵向的视图）。我如何纠正这个问题

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}

---

现在只需将新位置放入框架即可：

-(void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration{
    if(self.interfaceOrientation == UIInterfaceOrientationLandscapeLeft ||
       self.interfaceOrientation == UIInterfaceOrientationLandscapeRight){
        video1.frame = CGRectMake(50, 650, 150, 30);
        video2.frame = CGRectMake(350, 650, 150, 30);
    } else {
        video1.frame = CGRectMake(10, 10, 150, 30);
        video2.frame = CGRectMake(610, 10, 150, 30);
    }
}

让这一切保持原样

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return YES;
}

可以在要更改的方法中调用方向。所以它知道

例如：

-(void)videoDisplayMothod {
    //video code
    toInterfaceOrientation = UIInterfaceOrientationLandscapeLeft;
}

您是否定义了：

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

对于视图为纵向的控制器？（关闭视频后返回的那个）
