Swift if文の中にアラートを入れる方法

Last updated at Posted at 2019-09-12

自分用のメモです。

ネットで多く用いられている方法を使うとif文の中にアラートを入れられないのですが、以下のコードで試したところうまく行きました。

ViewVontroller.swift
//if分の中に挿入しても問題なく出せる。
let alert = UIAlertView()
alert.title = "Title"
alert.message = "My message"
alert.addButton(withTitle: "Ok")
alert.show()
