There is <code>UIPopOverController</code>, but its use is restricted to iPads:

<blockquote>
 Popover controllers are for use exclusively on iPad devices. Attempting to create one on other devices results in an exception.
</blockquote>

For the sake of those Googling this, <code>UIPopoverController</code> is now available for both iPhone and iPad. You can make popovers that look the same on both (as of iOS 9, I believe).

Step 1: Include <code>UIAdaptivePresentationControllerDelegate</code> and <code>UIPopoverPresentationControllerDelegate</code> on your class definition

Step 2: Override the presentation somewhere in your class like this:

<pre><code>func adaptivePresentationStyle(for controller: UIPresentationController) -&gt; UIModalPresentationStyle {
 return .none
}
</code></pre>

Step 3: When you present a view controller, you tell it to use <code>popover</code> style. Something like this:

<pre><code>//I pull my popover from a separate storyboard, but any modal view will do
let storyboard = UIStoryboard(name: "Popovers", bundle: nil)
let modal = storyboard.instantiateViewController(withIdentifier: "AnyPickerModal") as! AnyPickerVC
modal.modalPresentationStyle = UIModalPresentationStyle.popover

let pc = modal.popoverPresentationController
pc?.permittedArrowDirections = .any
pc?.sourceView = &lt;your button or view you tap to show the popover&gt;
pc?.sourceRect = &lt;your button or view&gt;.bounds

//How big the popover should be
modal.preferredContentSize = CGSize(width: 300, height: 180)

pc?.delegate = self

self.present(modal, animated: true, completion: nil)
</code></pre>

Your presented modal will show up as a popover on both iPhone and iPad. Attached is a screenshot from my iPhone app.

Happy coding!

Is there something similar to NSPopover for iOS apps? It appears in the Object library for Mac but not for iPhone nor iPad, although I have downloaded apps using this (or at least some very similar) feature.

So my question: Is there a legit way to implement this?

是否有类似于NSPopover的iOS应用程序？它出现在Mac的对象库中，而不是iPhone或iPad，尽管我已经使用这个特性(或者至少是一些非常类似的功能)下载了应用程序。那么，我的问题是:是否有一个合法的方式来实现这一点？
