如何创建类似于WhatsApp中出现的弹出菜单?

How can I create a popup menu like the one present in WhatsApp?

很抱歉，您的问题很愚蠢，但我什至不知道要搜索什么.我很确定它不是UIPickerView.

Sorry for the dumb question, but I don't even know what to search. I'm pretty sure it's not a UIPickerView.

推荐答案

这是具有actionSheet首选样式的UIAlertController.您可以像这样初始化一个:

This is a UIAlertController with an actionSheet preferred style. You can initialize one like this:

let alert = UIAlertController(title: nil, message: nil, preferredStyle: .actionSheet)

alert.addAction(UIAlertAction(title: "Action 1", style: .default) { _ in
   <handler>
})

alert.addAction(UIAlertAction(title: "Action 2", style: .default) { _ in
    <handler>
})

present(alert, animated: true)
