UIAlertView/UIAlertController iOS 7 and iOS 8 compatibility

Question

I am using Swift to write an app and I need to show an alert. The app must be iOS 7 and iOS 8 compatible. Since UIAlertView has been replaced with UIAlert

Answer 1

In iOS8, there is a new class UIAlertController that replaces UIAlertView and UIActionSheet. From iOS8 on, use UIAlertController, and for iOS8 and before use UIAlertView and UIActionSheet. I think that iOS8 added size classes that change UIAlertView display direction. See: https://github.com/wangyangcc/FYAlertManage
