Question

我看到很多关于这个问题的问题，但我无法找到解决我遇到的问题的方法。我创建了一个iPad应用程序，它应该只是Landscape - 它在iOS6之前的任何操作系统上运行时工作正常但在iOS6上应用程序以纵向视图打开。此屏幕截图显示了我的意思（抱歉，这不是一个很好的解释）http://s1342.beta.photobucket.com/user/designedbyria/media/ScreenShot2012-11-02at122113.png.html

我猜测问题出现在下面的代码中，但我无法确定。我已将支持的界面方向设置为仅横向左侧和横向右侧 - 但这不起作用。我也在这里看了一些没有运气的问题..

我正在使用xcode和cordova / phonegap

}


[self.window addSubview:self.viewController.view];
[self.window makeKeyAndVisible];

return YES; }

Answer 1

我遇到了同样的问题（但没有使用cordova / phonegap）。

您必须将视图控制器设置为appDelegate中的RootViewController，而不是仅仅添加为子视图。

替换你的appdelegate：

[self.window addSubview:self.viewController.view];
[self.window makeKeyAndVisible];

通过

[self.window setRootViewController:self.viewController];
[self.window makeKeyAndVisible];

Answer 2

您可以使用代理

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation

{
  return UIInterfaceOrientationLandscapeLeft;

}

使用此委托，应用程序将以横向模式或任何所需的方向模式显示。

试试吧。
