這是我的按鈕
Button(action: {
SearchSomeone()
},label: {
NavigationLink(destination: mySearchList()){
HStack(alignment: .center) {
Text("Search")
.font(.system(size: 17))
.fontWeight(.bold)
.foregroundColor(.white)
.frame(minWidth: 0, maxWidth: .infinity)
.padding()
.background(
RoundedRectangle(cornerRadius: 25)
.fill(Color("Color"))
.shadow(color: .gray, radius: 2, x: 0, y: 2)
)
}
這個按鈕同時執行功能和搜索，由于搜索需要時間，所以我看不到串列，我該如何執行該功能，然后在 8 秒后進行導航？謝謝

根據資訊，您想在 8 秒后切換到新視圖。這段代碼應該適合你。
import SwiftUI
struct ContentView: View {
//Variable to see if view should change or not
@State var viewIsShowing = false
var body: some View {
//Detecting if variable is false
if viewIsShowing == false {
//Showing a button that sets the variable to true
Button(action: {
//Makes it wait 8 seconds before making the variable true
DispatchQueue.main.asyncAfter(deadline: .now() 8.0) {
viewIsShowing = true
}
}) {
//Button text
Text("Search")
.font(.system(size: 17))
.fontWeight(.bold)
.frame(minWidth: 0, maxWidth: .infinity)
.padding()
.background(
RoundedRectangle(cornerRadius: 25)
.fill(Color("Color"))
.shadow(color: .gray, radius: 2, x: 0, y: 2)
)
}
} else {
//If the variable equals false, go here
View2()
}
}
}
//Your other view you want to go to
struct View2: View {
var body: some View {
Text("abc")
}
}
