iphone:在导航时强制将方向从纵向更改为横向

iphone: Forcefully change orientation from portrait to landscape on navigation(iphone:在导航时强制将方向从纵向更改为横向)

问题描述

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 ?

我有一个要求，在将控制器从 A 推到 B 时.B 应该是横向的，但我的 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.

推荐答案

在你的 ViewController-B 的 viewDidLoad 中添加这行代码:

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，则此代码可以正常工作.

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

我用过这个.

希望这会对你有所帮助.

Hope this will help you.

享受编码:)
