强制将视图控制器仅设置为纵向 [英] Force view controller to portrait only

问题描述

在我的应用程序中，我试图将视图控制器强制设置为仅纵向.我正在使用下面的代码，但实际上没有任何反应.我仍然可以像人像一样看到风景的屏幕吗?

In my application I am trying to force a view controller to be portrait only. I am using the code below but nothing is really happening. I am still able to see the screen in landscape as in portrait?

我在项目设置中启用了横向(左右)肖像.

I have enabled landscape (left/right), portrait in my project settings.

我做错了什么?

ViewController.m

ViewController.m

- (BOOL)shouldAutorotate
{
    return NO;
}

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
}

推荐答案

如果VC嵌入在导航或标签栏控制器中，则需要在该控制器上创建一个类别.这是一个允许导航控制器以各种方式旋转的示例:

If you VC is embedded in a navigation or tab bar controller you need to create a category on that controller. This is an example that allow navigation controller rotate in all ways:

#import "UINavigationController+RotationAll.h"

@implementation UINavigationController (RotationAll)

- (NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskAll;
}

@end
