column

I'm not sure I made my problem clearWhile I set the values in the table using the tableView method I'm allowing the user to change the values in the tableview by making the cells in the second column editable.I want to know how to retrieve the new values the user has entered from the table.I notice there are two versions of the tableView function. the first is called by the tableview to populate the cells.I'm unclear as to how/when the second version of the function is called:func tableView(tableView: NSTableView, setObjectValue object: AnyObject?, forTableColumn tableColumn: NSTableColumn?, row: Int) { an example of how to get the value for row n, column i of a tableview would be appreciated.Thanks for your help!

Why is there no toggle button above? What do you mean by toggle button? Do you mean the button that hides and shows the sidebar? This is only present when the horizontalSizeClass is .regular. On an iPhone in portrait mode, it won't appear. ‎ And why is the menu always showing? What menu are you talking about? ‎ I cant see the detiail view anymore If you want to see the detail view, you need to select an item from the list. As I said before, the two-column layout with the sidebar toggle button is only present when the horizontalSizeClass is .regular. In your screenshot (an iPhone in portrait mode) the NavigationSplitView collapses down to a single column layout and acts more like a NavigationStack.

I'm having the exact same issue but it seems to be confined to list and column views. I can't click the fourth item from the top whether it's a file or folder. Quite bizarre.

IB. but i also have 6 cells, each with a different image in it. its showing 6 cells in 2 columns, exactly like i want it to, but its all the same cell, just repeated, and very small

What doesn't work ? I have opened A projet Targets, selected Info. I could resize the Key column at will. Not the Type nor Value. Can you describe exactly the problem (SO capture is not very explicit of the problem).

This is a very essential question since it would give us the possibilities to show/hide table columns dynamically which is not possible another way. So I am asking the same. Can someone provide a complete working solution ?

I'm trying to do it in Swift Playgrounds and here's my code: import PlaygroundSupport let columns: [GridItem] = [GridItem(.flexible()), GridItem(.flexible()), GridItem(.flexible())] struct ContentView: View { var body: some View { GeometryReader { geometry in VStack { Spacer(minLength: 290) Text(text) .font(.largeTitle) ZStack { LazyVGrid(columns: columns) { Group { Button { } label: { ZStack { Circle() .frame(width: 90, height: 90) .foregroundColor(Color(.systemBlue)) .opacity(0.5) //.position(x: geometry.size.width/2, y: -100) Text(5) .font(.largeTitle) .bold() .foregroundColor(.black) } .frame(width: 90, height: 90) } } } } } } } } PlaygroundPage.current.setLiveView(ContentView()) I've created a text and I would like that the text will change on the press of the button. For example: there's a Text() witch now has written on it text and when I press the blue button (you can see it in my code), I want text to change to number 5

I edited with <> to make it more readableimport UIKit class testVCViewController: UIViewController, UICollectionViewDelegate, UICollectionViewDataSource, UICollectionViewDelegateFlowLayout, ImagesCVLayoutDelegate { @IBOutlet weak var cv: UICollectionView! @IBOutlet weak var btn: UIButton! @IBAction func btn(_ sender: UIButton) { items.remove(at: 0) cv.deleteItems(at: [IndexPath(row: 0, section: 0)]) // THIS IS WHERE THE WARNINGS AND ERROR OCCUR. cv.reloadData() } var items = [1,2,3,4,5,6,7,8,9] // Data source. func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int { return items.count } func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell { let cell = collectionView.dequeueReusableCell(withReuseIdentifier: cell, for: indexPath) as! zCollectionViewCell cell.lbl.text = (items[indexPath.row]) return cell } func numberOfSections(in collectionView: UICollectionView) -> Int { return 1 } func co

Actually, I was able to get the content displayed. Following guide was helpful although different then what is current working:https://developer.apple.com/library/content/documentation/Cocoa/Conceptual/TableView/PopulatingView-TablesProgrammatically/PopulatingView-TablesProgrammatically.htmlI then had to match the identifier of the cell with the column.

As works fine thanks. :-)I seem to have a problem with the identifier not working. The result is always nil not sure why, I set up an ident for the column but the rest of the hierarchy items are default. Where is the ident being called from ?

One workaround would be to change my model to not have nullable fields, and set to when decoding a null. However, that to me, is a kludge. My model data is coming from a database table in Postgres where the column(s) are NULLABLE.

I found that appending an .id modifier to the detail column resolved the problem for me: } detail: { if let selectedCocktail { CocktailDetailView(pCocktail: selectedCocktail) .navigationTitle((selectedCocktail.favorite ? (profile.userData.favoriteCocktailsIcon.rawValue) : ) (selectedCocktail.cocktailName ?? )) .id(selectedCocktail.id) //workaround }

Pretty straightforward, I think, in that children always inherit from parents.If you're asking for a tool/menu that allows you to visualize them, the left column in IB's editor is sorted on hierarchy, just be sure to toggle everything to show.

So I start off with a structure like so:Table ColumnTable Cell View Table View Cell Table View Cell Number FormatterText CellTable ColumnTable Cell View Table View Cell <=- I delete this one Table View CellText CellSo I then delete the one that I pointed at, which is the one I think you're telling me to, so it and the one child go away. Now I drag a check cell into that second column, and then suddenly stuff from other columns disappear as well, and I'm left with this:Table ColumnText CellTable ColumnCheckWhat did I do wrong?
