如何在单击按钮时在SwiftUI中为TextField设置文本

Question

我想在单击按钮的Textfield中为SwiftUI设置文本。我尝试使用@State变量，但变量给出错误

Answer 1

尝试以下代码（已在Xcode中测试：11.2.1）

struct ContentView: View {

   @State var name: String = ""
   var body: some View {

       VStack {
           TextField("Please enter", text: $name)
           Button(action: {
               self.name = "Hello text"
           }) {
               Text("Press")
           }
       }
   }
}

您可以创建按钮状波纹管的动作

@State var name: String = "My Name is jack"

   var body: some View {

       VStack {
           TextField("Name:", text: $name)
           Button(action: {
               self.name = "My Name is Tim"
           }) {
               Text("Change Name")
           }
       }
   }
