Good day to all,
I have a weird problem with tapping on a button inside collection view cell when search results controllers is active.
So, I'm initializing searchController like this:
private let searchController = UISearchController(searchResultsController: nil)
In my viewDidLoad():
searchController.searchResultsUpdater = self
searchController.obscuresBackgroundDuringPresentation = false
searchController.definesPresentationContext = true
navigationItem.searchController = searchController
Making data source:
private func makeDataSource() -> DataSource {
let cellRegistration = UICollectionView.CellRegistration(
handler: CellProvider().cellRegistrationHandler
)
return DataSource(collectionView: collectionView) {
(collectionView: UICollectionView,
indexPath: IndexPath,
item: IngredientViewData) in
return collectionView.dequeueConfiguredReusableCell(
using: cellRegistration,
for: indexPath,
item: item
)
}
}
Nothing fancy.
In the CellProvider:
var buttonConfiguration = addButtonConfiguration(for: item)
buttonConfiguration.tintColor = .systemBlue
cell.accessories = [
.customView(configuration: buttonConfiguration),
.disclosureIndicator(displayed: .always)
]
cell.contentConfiguration = contentConfiguration
private func addButtonConfiguration(for item: IngredientViewData) -> UICellAccessory.CustomViewConfiguration
{
let symbolName = item.isSelected ? "checkmark.circle" : "circle"
let symbolConfiguration = UIImage.SymbolConfiguration(textStyle: .title1)
let image = UIImage(
systemName: symbolName,
withConfiguration: symbolConfiguration
)
let button = AddButton()
button.addTarget(
nil,
action: #selector(IngredientsCollectionViewController.didPressDoneButton),
for: .touchUpInside
)
button.id = item.id
button.setImage(image, for: .normal)
return UICellAccessory.CustomViewConfiguration(
customView: button, placement: .leading(displayed: .always))
}
Pretty basic setup. Simple button and selector to the view controller.
Tapping works fine when searchController is not active. And if it is, then IngredientsCollectionViewController.didPressDoneButton won't be called.
What am I missing?

Hi all,
I'm developing an app that uses a coordinator pattern. I have a router that presents modally view controllers passed to it. It basically adds the passed view controller to the navigation controller and attaches a cancel navigation bar button.
This way I have the flexibility to present any view controller either modally or push it.
The problem is PHPickerViewController. It has its own "add" and "cancel" buttons which I don't how to disable. It seems that they are not in view controller's navigation bar.
And doing something like this:
navigationController.setViewControllers([phPickerViewController], animated: false)
just adds another navigation bar on top. That looks ugly.
How can I overwrite the default PHPickerViewController's "navigation bar"?
// I can make a customer PHPickerViewController or, easier, a custom router for it, but that seems like a lot of custom work for such a simple thing. I'd rather make a proper configuration in coordinator...
Hey all,
I'm developing a fully programmatically app (not sure if it matters) and get to the point where I want to localize it.
Most of my strings are look like this:
swift
cell.label.text = localized("Hello world")
where localized() is just a wrapper around NSLocalizedString():
swift
func localized(_ string: String) - String {
return NSLocalizedString(string, comment: "")
}
So, I added desirable languages to my project and created *.strings file, but when I do
bash
find ./ -name "*.swift" -exec echo {} \; -exec genstrings -s localized -a -o Resources/en.lproj {} \;
I get a lot of errors:
genstrings: error: bad entry in file ./bla-bla/myfile.swift (line = 30): Argument is not a literal string.
So, it seems that genstrings doesn't work with wrappers, though the man states:
s routine [-s routine ...]
Recognizes routine() as equivalent to NSLocalizedString(). For example, -s MyLocalString will catch calls to MyLocalString(), MyLocalStringFromTable(), and so on.
Am I missing something? Is there any way to generate a strings file except looking for some better tools on GitHub/creating my own?
Hi all,I have a static TableView with text fields. I want them to have the same width, but I can't make "relative constraint" (with ctrl, or how it's called) to each other because they placed in different cells. As a workaround, I made fixed width constraints, but now xcode shows warnings "fixed width constraints may cause clipping". So I wonder if there is a better way?Those text fields are for numbers only, so probably there will be no localization issues.
