按下后退按钮时旋转至纵向
[英]Rotate to Portrait Orientation when back button pressed
问题描述
Hey, I have an issue were I allow one viewcontroller to be displayed in portrait and landscape, however when the user hits the back button I want to switch the apps orientation back to portrait. 
嘿，我有一个问题是我允许一个ViewController以纵向和横向显示，但是当用户单击“后退”按钮时，我想将应用的方向切换回纵向。 At present if the user hits the back button when its in landscape mode the rest of the application stays in landscape mode, has anyone came across a solution for auto-rotating? 目前，如果用户在横向模式下单击后退按钮，则应用程序的其余部分保持横向模式，是否有人遇到过自动旋转的解决方案？
[EDIT] [编辑]
The effect is similar to what occurs when use [[UIDevice currentDevice] setOrientation:UIInterfaceOrientationPortrait]; 效果类似于使用[[UIDevice currentDevice] setOrientation:UIInterfaceOrientationPortrait]; but this is a hidden API method :-( 但这是一个隐藏的API方法:-(

What I got from your question is you want to rotate only one view portrait and landscape. 我从您的问题中得到的是，您只想旋转一幅肖像和风景。 If that is what you want, then just go to method - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 如果那是您想要的，那么只需转到方法-（BOOL）应该AutorotateToInterfaceOrientation：（UIInterfaceOrientation）interfaceOrientation
and then return true then your only that view will rotate. 然后返回true，那么您唯一的那个视图将旋转。
