iOS6旋转问题：从另一个视图控制器弹出时，使我的视图保持直立

Question

I have two viewcontrollers, ViewControllerA supports both landscape and portrait, click a button in ViewControllerA push into ViewControllerB, which supports landscape only, then I make the phone in the landscape direction and then pop back to ViewControllerA, by default A is in landscape mode now, but I want it to be portrait first in this situation. How can I implement that?

Answer 1

在您的ViewControllerA的viewwillappear方法中，将方向设置为

[[UIDevice currentDevice]setOrientation:UIInterfaceOrientationPortrait];
