Hello I am new to swiftUI and am making my first app, my current issue is that I am not sure if it is possible to hide my navigation bar while scrolling using the methods I got from a nav bar tutorial I found. I have tried to implement the UINavigationBar stuff but I don't think its at all compatable with what I have so far. I'm pretty sure if I wanted to go that route I would have to rewrite most of what I have to fit that format.
I was hoping that maybe I am missing a step when doing this so I don't have to rewrite what I have
here's my current code
import Foundation
import SwiftUI
struct ContentView: View{
@State var showMenu = false
@State var scoreUp = false
@State var commentP = false
@State var tags = false
@State var sauce = false
var body: some View{
let drag = DragGesture()
.onEnded {
if $0.translation.width < -100 {
withAnimation {
self.showMenu = false
}
}
}
let dragOpen = DragGesture()
.onEnded {
if $0.translation.width > 100 {
withAnimation {
self.showMenu = true
}
}
}
return NavigationView {
GeometryReader { geometry in
ZStack(alignment: .leading) {
/// this is the main view for the second page allowing most of the app features
MainView(showMenu: self.$showMenu, scoreUp: self.$scoreUp, commentP : self.$commentP,tags : self.$tags,sauce :self.$sauce)
.frame(width: geometry.size.width, height: geometry.size.height)
.offset(x: self.showMenu ? geometry.size.width/2 : 0)
.disabled(self.showMenu ? true : false)
.gesture(dragOpen)
if self.showMenu {
HamburgerMenuView(showMenu: self.$showMenu)
.frame(width: geometry.size.width/2, height: geometry.size.height)
.transition(.move(edge: .leading))
.gesture(drag)
}
if self.scoreUp {
// TO DO : MAke this button score up a post
Image(systemName: "arrow.up")
.animation(.interpolatingSpring(stiffness: 50, damping: 1), value: 10)
}
}
}
.navigationBarItems(leading: (
Button(action: {
withAnimation {
self.showMenu.toggle()
}
}) {
Image(systemName: "line.horizontal.3")
.imageScale(.large)
}
))
}
}
}
