SwiftUI专辑040-显示confirmationDialog

· 预计阅读1分钟

headerimg Confirmation dialogs 是 iOS 15 开始出现的。

他和Actionsheet类似，不过Actionsheet已经被废弃了。

Getting ready​

首先新建一个SwiftUI项目：PresentingConfirmationDialogs

How to do it​

  1. 定义个State控制是否显示confirmationDialog
@State private var showDialog = false
var title  = "Confirmation Dialog"
  1. 添加个按钮，点击后，显示confirmationDialog
var body: some View {
    Button("Present Confirmation Dialog") {
        showDialog = true
    }.confirmationDialog(title, isPresented: $showDialog) {
        Button("Dismiss Dialog", role: .destructive) {

        }
        Button("Save") {

        }
        Button("Cancel", role: .cancel) {

        }
        Button("Print something to console") {
            print("something")
        }
    } message: {
        Text("""
             Use Dialogs to give users alternatives for
             completing a task
            """)
    }
}
