在iOS 7中强制使用Landscape ViewController [英] Force Landscape ViewController in iOS 7

问题描述

我在纵向模式下有十多个ViewControllers，但无论设备的方向如何，我都需要在横向模式下强制使用一个。

I have more than ten ViewControllers in portrait mode, but I need to force a single one in Landscape mode regardless of the device´s orientation.

推荐答案

以下是解决方案：

1）将LandscapeViewController嵌入到子类的NavigationController中，并使用模态segue从PortraitViewController连接它。

1) Embed the LandscapeViewController in a subclassed NavigationController and connect it from your PortraitViewController using a modal segue.

2）子类UINavigationController

2) Subclass UINavigationController

LandscapeNavigationController.m

LandscapeNavigationController.m

-(BOOL)shouldAutorotate
{
    return NO;
}

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscapeLeft;
}

3）不要忘记解雇你的模态VC（在这种情况下来自我的Bar Buttom项目动作）

3) Don't forget to dismiss your modal VC (in this case from my Bar Buttom Item Action)

- (IBAction)goBack:(id)sender
{
    [self.navigationController dismissViewControllerAnimated:YES completion:nil];
}
