I am trying to get data from one view to another.
I can not figure out how to get values from the fourth view array into the Third view.
I am not using storyboards. I tried using @EnvironmentObject but can not make it work. New to coding. In xcode I am using watchos without app.
I tried to strip out most of the code and leave just the important stuff that can be tested. I used NavigationLink(destination: )to transfer between views.
enter code here
class viewFromEveryWhere: ObservableObject {
@Published var testname2: String = "testTTname"
}
struct secondView: View {
var body: some View {
Text("second view")
List(1..<7) {
Text("\($0)")
}
}
}
struct thirdView: View {
@EnvironmentObject var testname2: viewFromEveryWhere
@EnvironmentObject var testSixTestArray: viewFromEveryWhere
@State var sixTestArray:[String] = ["ww","GS","DW","CD","TS","JW",]
var body: some View {
List(sixTestArray, id:\.self) {
Text($0)
}
}
}
struct fourthView: View {
@StateObject var testname2 = viewFromEveryWhere()
@State private var name: String = ""
@State var testSixTestArray:[String] = []
func collectName () {
print("collectName triggered")
if testSixTestArray.count < 5 {
// testSixTestArray.append(name)
print(name)
print(testSixTestArray)
}
// .enviromentObject(testSixTestArray)
}
var body: some View {
VStack(alignment: . leading) {
Text("Type a name")
TextField("Enter your name", text: $name)
Text("Click to add, \(name)!")
// Button("click this if \(name) is correct") {}
Button(action:{
print("Button Tapped")
collectName()
print(testSixTestArray.count)
name = ""
}) {
Text("Add \(name) to list")
}
// .buttonStyle(GrowingButton1())
}
Text("forth view")
// testSixTestArray.append(name)
.environmentObject(testname2)
}
}
/*func presentTextInputControllerWithSuggestions(forLanguage suggestionsHandler:
((String)-> [Any]?)?,
allowedInputMode inputMode:
WKTextInputMode,
completion: @escaping ([Any]?) -> Void) {}
*/
struct ContentView: View {
@State var sixNameArray:[String] = ["","","","","","",]
@State var messageTextBox: String = "Start"
@State var button1: String = "Button 1"
@State var button2: String = "Button 2"
@State var button3: String = "Button 3"
var body: some View {
NavigationView {
VStack{
Text(messageTextBox)
.frame(width: 120, height: 15, alignment: .center)
.truncationMode(.tail)
.padding()
NavigationLink(destination: secondView(),
label:{
Text(button1)
})
.navigationBarTitle("Main Page")
NavigationLink(destination: thirdView(),
label:{
Text(button2)
})
NavigationLink(destination: fourthView(),
label:{
Text(button3)
})
}
}
}
}
