QUESTION
I am using TabView
in my SwiftUI app. I used the side Preview as I was building it. The bottom tab shows on all device types in the Preview section but when I build it to either a real device or simulate device, the TabView doesn't show at all.
ANSWER
Answered 2021-Jun-08 at 20:40Previews are for each individual view. They don't represent the whole app.
You'll need to set it as the root view inside YourAppName_App.swift
.
QUESTION
I am currently trying to use TabView for carousel view(PageTabViewStyle) with CoreData.
The error doesn't occur, when I add a new page in order like this age.name: 3, page.name: 4, page.name: 5
But the error occurs, if I put a number in the first/middle order like page.name: 2
If I put page.name: 6, then no error and it's also same with Alphabet. b c d e -> put "f", no problem, but put "a" error.
After turn off the app and open the app, then I see the updated(Page added/Page deleted) ContentView anyway.
I guess, TabView has a sorting problem, so I tried to sort the list of CoreData, change LifeCycle to SwiftUI, but the error occurs again and again. I've also tried with Firebase, but the same problem.

QUESTION
I am trying to set a bigger font in the tab bar's title fields, but it doesn't work. What I tried changes the size of the icon and the font of the text field in the view. The title in the bar remains unchanged. As you can see I tried many ways (commented lines) and neither of them works.

QUESTION
I'm new to SwiftUI and MVVM, and the whole though process around @Published is still not making total sense to me.
In my contentView, I have an observable object that reads from a class that adopts the ObservedObject protocol.
Content View:

Answered 2021-May-21 at 20:53If ExerciseSelector and its array is your "single source of truth" then you need to do something like you have already done so that both views can use the same instance. Another option to look into is to use a @EnvironmentObject which is a different way of achieving basically the same. See this article for instance to learn about EnvironmentObject
QUESTION
I have a Main View that contains multiple Views and picks one based on the value change of a variable in a ObservabledObject, which change on buttons press.
The problem comes when I select a View that contains input fields, in that case, when I tap on a TextField, instead of showing the keyboard, it takes me back to the Homepage View.
It only happens on devices, not on simulators.
Though, it works if you set that specific view (the one with TextField) as Main View (the first case in the Switch).
Here's the ObservableObject Code:

QUESTION
I've been trying to create a TabView with PageIndexViewStyle
where each page is a ScrollView that contains an image and a WebView. The example code here from @Asperi works great when I'm creating a page outside of the TabView, but when I move things inside the TabView, the WebView on the second page isn't displayed.
ANSWER
Answered 2021-May-12 at 16:08I can't exactly tell you what is causing that odd behaviour but setting the selection
parameter of the TabView
solved the problem.
From my understanding, SwiftUI
wanted us to provide a selection binding
on our TabView
.

QUESTION
It was mentioned in some of my other threads on my app on that my code was incorrect because the apply button is present. I understand that now. It was said to collect the controls and then when apply is hit to send the data.
I have now idea how to approach that. So for the sake of general education. I have 1 property sheet
and 5 property pages
. For the sake of just general controls in use. Between all the 5, there are only radio
controls and buttons
, no edit controls
(yet).
Let's assume there are 2 radios buttons
and 1 button
on each page.. where page 1
is radio1
, radio2
, button 1
and page 2
is radio3
, radio4
, button2
....and so on.
I know that when the user selects something like a button or radio that the IsModified(TRUE)
needs to be called to enable the apply button from grayed to active.
What would the code look like to scan all the controls and then apply them? I've never done it and I can't seem to find an example that isn't already super busy to gain the understanding of how to do it.
Anyone have a tutorial or code snippet or build a primer from the controls that I described above that could demonstrate how to execute this?
Update:Ok so I have the DDX variables added:
...ANSWER
Answered 2021-May-10 at 21:15Below is an example of an application I wrote some time ago. It's a simple "Settings" dialog. Unlike yours, this one is derived from CDialogEx
. But as CPropertyDialog
is derived from CDialog
, these apply in your case too.
Using the Wizard, I added member variables to the dialog class, bound to the dialog controls. Choose "Value", rather than "Control" in the "Category" combo in the Wizard. These are declared in the class definition. For simplicity, I only show three. There is a CString, an int and a BOOL variable, bound to an edit, a combo-box (drop-down list) and a check-box control respectively.
