SwiftUI的Alert使用方式

记录一下SwiftUI的Alert使用方式，比较简单直接上代码

import SwiftUI

struct AlertBootCamp: View {
    @State var showAlert = false
    var body: some View {
        Button {
            showAlert.toggle()
        } label: {
            Text("alert show")
        }
        /// 单按钮
//        .alert(isPresented: $showAlert, content: {
//            Alert(title: Text("this is a alert!"))
//        })
        .alert(isPresented: $showAlert, content: {
            Alert(title: Text("title"), message: Text("message"), primaryButton: .default(Text("sure"), action: {
                print("sure")
            }), secondaryButton: .cancel(Text("cancel"), action: {
                print("cancel")
            }))
                             
        })
        
    }
    
}

#Preview {
    AlertBootCamp()
}
