請幫我解決這個問題：
重現我的問題的步驟：
點擊“編輯我的名字”按鈕
在 .sheet 中，點擊 TextField，然后在仍然顯示鍵盤的情況下，一直向下滾動
點擊“洗掉姓名”按鈕
這是問題所在：
確認對話框只出現一秒鐘，然后消失，沒有給用戶任何機會（或少于一秒鐘的機會）點擊確認對話框的按鈕之一！
這是我的代碼：

uj5u.com熱心網友回復：
如果您將其.confirmationDialogue移出Form：
struct EditView: View {
@Binding var name: String
@State private var isShowingConfirmationDialog = false
var body: some View {
Form {
Section {
TextField("Name", text: $name)
}
Section {
VStack {
ForEach(0..<50, id: \.self) { number in
Text("\(number)")
}
}
}
Section {
Button("Delete Name", role: .destructive) {
isShowingConfirmationDialog = true
}
}
}
.confirmationDialog("Are you sure you want to delete name?", isPresented: $isShowingConfirmationDialog) {
Button("Delete Name", role: .destructive) {
name = ""
}
Button("Cancel", role: .cancel) { }
} message: {
Text("Are you sure you want to delete name?")
}
}
}
