iphone:在导航时强制改变从纵向到横向的方向

问题描述:

我们有什么方法可以在导航时强制将应用方向从纵向更改为横向?

Is there any way that we can Forcefully change app orientation from portrait to landscape while navigating ?

我要求将控制器从A推送到B. B应该是横向的,但是我的A控制器是纵向的。

I have a requirement that while pushing controller from A to B. B should be in landscape but my A controller is in portrait.

在你的ViewController-B中,在viewDidLoad中添加以下代码行:

In your ViewController-B add this lines of code in viewDidLoad:

  [[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight];

  float   angle = M_PI/2;  //rotate 180°, or 1 π radians
  self.view.layer.transform = CATransform3DMakeRotation(angle, 0, 0.0, 1.0);

如果您使用导航控制器从A移动到B,此代码工作正常。

This code is working fine if you are using navigation controller to move from A to B.

我用过这个。

希望这会对你有帮助。

享受编码:)
