强制一个视图控制器ios的景观 [英] Force landscape for one view controller ios

问题描述

我已经看过类似问题的几个答案，但答案都没有。我有一个应用程序，我需要一切portait除了我有一个照片查看器。在目标菜单的支持方向部分，我只有肖像。如何强制我的一个视图成为风景。它正从导航控制器推入堆栈，但我正在使用故事板来控制所有这些。

I've looked at several answers to questions similar but none of the answer worked. I have an app where I need everything portait except for one photo viewer I have. In the supported orientations section of the targets menu I only have portrait. How do I force my one view to be landscape. It is being pushed onto the stack from a nav controller but I'm using storyboards to control all that.

推荐答案

自答案以来似乎隐藏在问题的评论中，因为ArunMak的答案非常令人困惑，我只会提供我发现的内容：

Since the answer seems to be hidden in the comments of the question and since ArunMak's answer is quite confusing, I'll just offer what I found out:

我所要做的就是将此函数添加到视图的自定义UIViewController子类中：

All I had to do was to add this function to my custom UIViewController subclass for the view:

- (NSUInteger)supportedInterfaceOrientations {
    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
        // iPad: Allow all orientations
        return UIInterfaceOrientationMaskAll;
    } else {
        // iPhone: Allow only landscape
        return UIInterfaceOrientationMaskLandscape;
    }
}

请注意，项目需要允许所有方向（是：纵向，横向左侧，横向右侧 - 但在iPhone上永远不会颠倒！）。

Note that the project needs to allow all orientations (that is: Portrait, Landscape Left, Landscape Right - but NEVER Upside Down on an iPhone!).

如果您想将部分或大部分视图限制为纵向，则需要在每个视图控制器中实现上面的方法（或者为它使用一个公共超类，并从中继承所有其他视图控制器） - 如果你将Info.plist中的设备方向限制为只是肖像，应用程序将永远不会想到去进入景观。

If you want to limit some or most views to Portrait, you need to implement the above method in every of those view controllers (or use a common super class for it and subclass all others from it) — if you limit the Device Orientation in the Info.plist to just Portrait, the app will never even think of going into landscape.
