如何在SwiftUI上创建/使用\ .Identifier？

Question

我已经使用pod创建分页滚动：

https://github.com/fermoya/SwiftUIPager

但是，有些错误描述得不够充分。

1. 我已创建

   struct ContentView: View {
       @State private var page = 0
       ...
   }
   

2. self.levels = ["img1", "img2"...]

   3。

   struct cardView: View {
   
   var item : String
   @Binding var page: Int
   let screenW = UIScreen.main.bounds.width
   let screenH = UIScreen.main.bounds.height
   let sceneButtonH = UIScreen.main.bounds.height * 0.6494
   let sceneButtonW = (UIScreen.main.bounds.height * 0.6494) * 1.0867
   let buttonPadding = ((UIScreen.main.bounds.height * 0.6494) * 1.0867) * 0.26
   
   var body: some View{
   
           Button(action: {
               //self.showingDetail.toggle()
           }) {
               Image(uiImage: UIImage(named: item )!)
                   .renderingMode(.original)
                   .resizable()
                   .aspectRatio(contentMode: .fit)
                   .padding(.leading, buttonPadding/2)
                   .padding(.trailing, buttonPadding/2)
           }
   }
   
   }
   

如何创建.identifier？这是一个自定义方法？

Answer 1

根据您的代码，假设self.level为[String]。如果是，请尝试使用id：\ .self

谢谢！
