ios - Material 设计 snackbar 在 swift 4 中不起作用

Question

作为materialdesign.io给出的代码

let action = MDCSnackbarMessageAction()
let actionHandler = {() in
    let message = MDCSnackbarMessage()
    message.text = "Please complete your KYC detail"
    MDCSnackbarManager.show(message)
 }
 action.handler = actionHandler
 action.title = "OK"
 message.action = action

我已经尝试了所有方法，但是 google Materialdesign.io 的这段代码不起作用。

Answer 1

你可以像这样使用 Snackbar

let message = MDCSnackbarMessage()
message.text = "Item Closed"

let action = MDCSnackbarMessageAction()
let actionHandler = {() in

    let answerMessage = MDCSnackbarMessage()
    answerMessage.text = "Item Opened"
    MDCSnackbarManager.show(answerMessage)

}
action.handler = actionHandler
action.title = "UNDO"
message.action = action
MDCSnackbarManager.show(message)
