在Swift iOS中设置设备方向 [英] Setting device orientation in Swift iOS

问题描述

我正在开发一款适用于iPhone的快速应用程序。在我的应用程序中有一个模态视图，我只想在纵向视图中。

I am working on a swift app for iPhone. There is a modal view in my application that I want only to be in portrait view.

我的问题是，如何以编程方式强制手机不允许旋转？换句话说，我正在寻找不允许以横向模式显示模态视图的代码（打开纵向旋转锁定）。

My question is, how do I programmatically force the phone to not allow rotation? In other words, I am looking for code that will not allow a modal view to be displayed in landscape mode (turning on portrait rotation lock).

这仅适用于1模态视图，所以我无法关闭整个应用程序的旋转，否则我只会完全禁用旋转。

This is just for 1 modal view, so I can't turn off rotation for the entire app, otherwise I would just disable rotation altogether.

我在研究中找到了代码在哪里
但它是在客观C中，如果有帮助的话。谢谢！

I found code in my research here But it is in objective C, in case that helps. Thanks!

推荐答案

您可以将这些方法粘贴到需要为肖像的每个视图的ViewController中：

You can paste these methods in the ViewController of each view that needs to be portrait:

override func shouldAutorotate() -> Bool {
    return false
}

override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
    return UIInterfaceOrientationMask.Portrait
}
