Warning when presenting UIActivityViewController inside a SwiftUI sheet - ios

Question

I use UIActivityViewController to allow my SwiftUI app to share content with other activities:
import Foundation
import SwiftUI
struct ShareSheet : UIViewControllerRepresentable{
var items: [Any]
func makeUIViewController(context: Context) -> UIActivityViewController {
let ac = UIActivityViewController(activityItems: items, applicationActivities: nil)
return ac
}
func updateUIViewController(_ uiViewController: UIActivityViewController, context: Context) {
}
}
To make it clear, I will use the following simple code:
import SwiftUI
struct ContentView: View {
#State var showForImageShare: Bool = false
var body: some View {
VStack {
Image(systemName: "globe")
.imageScale(.large)
.foregroundColor(.accentColor)
Text("Hello, world!")
.onTapGesture {
showForImageShare.toggle()
}
}
.sheet(isPresented: $showForImageShare){
let image = "Hello everybody"
ShareSheet(items: [image])
}
}
}
I got the following warning in the console:
2022-10-23 23:41:07.692216+0300 Test UIActivityViewController[92164:30374157] [LayoutConstraints] Changing the translatesAutoresizingMaskIntoConstraints property of a UICollectionReusableView that is managed by a UICollectionView is not supported, and will result in incorrect self-sizing. View: <_UIActivityContentFooterView: 0x15cd56340; baseClass = UICollectionReusableView; frame = (16 244.333; 361 52); layer = <CALayer: 0x600001ab8180>>
I use Xcode 14, Deployment Target: 16.0
Could you please help me to find the best way to present UIActivityViewController ?

Answer 1

How about this?
import SwiftUI
struct ContentView: View {
#State private var isActivityViewPresented = false
var body: some View {
Button("Share Link") {
self.isActivityViewPresented = true
}
.background(
ActivityView(
isPresented: $isActivityViewPresented,
activityItmes: [URL(string: "https://stackoverflow.com/questions/74174661/warning-when-presenting-uiactivityviewcontroller-inside-a-swiftui-sheet")!]
)
)
}
}
public struct ActivityView: UIViewControllerRepresentable {
#Binding var isPresented: Bool
public let activityItmes: [Any]
public let applicationActivities: [UIActivity]? = nil
public func makeUIViewController(context: Context) -> UIViewController {
UIViewController()
}
public func updateUIViewController(_ uiViewController: UIViewController, context: Context) {
let activityViewController = UIActivityViewController (
activityItems: activityItmes,
applicationActivities: applicationActivities
)
if isPresented && uiViewController.presentedViewController == nil {
uiViewController.present(activityViewController, animated: true)
}
activityViewController.completionWithItemsHandler = { (_, _, _, _) in
isPresented = false
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
