UIAlertController の title と message のパターン

Last updated at Posted at 2020-01-21

毎回 title と message のどっちを設定するとどうなるかを忘れるので表にしてみました

style = actionSheet のときに title あり/message = nil と title = nil/message あり のパターンで後者の方がフォントが太くなるあたりが見どころです

UIAlertController.Style.alert

not empty message empty message nil message
not empty title alertTextText alertTextEmpty alertTextNil
empty title alertEmptyText alertEmptyEmpty alertEmptyNil
nil title alertNilText alertNilEmpty alertNilNil

UIAlertController.Style.actionSheet

not empty message empty message nil message
not empty title actionSheetTextText actionSheetTextEmpty actionSheetTextNil
empty title actionSheetEmptyText actionSheetEmptyEmpty actionSheetEmptyNil
nil title actionSheetNilText actionSheetNilEmpty actionSheetNilNil
