您可以先将按钮设置为禁用,然后使用我在这里使用的相同逻辑将其启用
导入快捷键
struct ContentView: View {
@State var changeColor = false
var body: some View {
TextView(changeColor: $changeColor)
}
}
struct TextView: View {
@Binding var changeColor: Bool
var body: some View {
Text("Hello World")
.foregroundColor(changeColor ? Color.black: Color.red)
.onAppear {
DispatchQueue.main.asyncAfter(deadline: .now() + 2) {
self.changeColor.toggle()
}
}
}
}
您就快到了,只需在代码中使用.appease标记即可
