Swiftui 来自另一个绑定值的init state变量-初始化前自用的变量

我试图用一个条件子句初始化一个切换选择器。如果显示“自由”计划，则默认情况下应选择该计划（选项3）。我正在努力从绑定showFreeversion初始化状态

struct PricingView: View {
    @Binding var isPresented: Bool
    @Binding var showFreeVersion: Bool
    @State private var selectedPrice: Int
    
    init(isPresented: Binding<Bool>, showFreeVersion: Binding<Bool>) {
        self._isPresented = isPresented
        self._showFreeVersion = showFreeVersion
        self.selectedPrice = showFreeVersion.wrappedValue ? 3 : 0
    }

但是如果我将状态初始化为0，如果有免费版本，默认情况下它不会更改为3

非常感谢，

您应该如下初始化状态

init(isPresented: Binding<Bool>, showFreeVersion: Binding<Bool>) {
    self._isPresented = isPresented
    self._showFreeVersion = showFreeVersion
    self._selectedPrice = State(initialValue: showFreeVersion.wrappedValue ? 3 : 0)
}

init（isPresented:Binding，showFreeVersion:Binding）{
self.\u isPresented=isPresented
self.\u showFreeVersion=showFreeVersion
self.\u selectedPrice=State（初始值：showFreeVersion.wrappedValue？3:0）
}

init(isPresented: Binding<Bool>, showFreeVersion: Binding<Bool>) {
    self._isPresented = isPresented
    self._showFreeVersion = showFreeVersion
    self._selectedPrice = State(initialValue: showFreeVersion.wrappedValue ? 3 : 0)
}
