I want my user to be able to edit his image right after he picks it with the new PHPickerViewController, I was able to do it with UIImagePickercontroller like so:
struct ImagePicker: UIViewControllerRepresentable {
@Environment(\.presentationMode) var presentationMode
@Binding var image: UIImage?
typealias UIViewControllerType = UIImagePickerController
var sourceType : UIImagePickerController.SourceType = .camera
class Coordinator: NSObject, UINavigationControllerDelegate, UIImagePickerControllerDelegate {
let parent: ImagePicker
init(_ parent: ImagePicker) {
self.parent = parent
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey: Any]) {
if let uiImage = info[.editedImage] as? UIImage {
parent.image = uiImage
} else {
print("no image!")
}
parent.presentationMode.wrappedValue.dismiss()
}
}
func makeUIViewController(context: UIViewControllerRepresentableContext<ImagePicker>) -> UIImagePickerController {
let picker = UIImagePickerController()
picker.sourceType = sourceType
picker.allowsEditing = true
picker.delegate = context.coordinator
return picker
}
func updateUIViewController(_ uiViewController: UIImagePickerController, context: UIViewControllerRepresentableContext<ImagePicker>) {
}
func makeCoordinator() -> Coordinator {
Coordinator(self)
}
}
But, when updating to Xcode 12.0 I need to support the iOS 14.0 users by implanting the PHPickerViewController like so:
@available(iOS 14, *)
struct PHPicker : UIViewControllerRepresentable {
func makeCoordinator() -> Coordinator {
return PHPicker.Coordinator(parent1: self)
}
@Binding var image : UIImage?
@Binding var picker : Bool
func makeUIViewController(context: Context) -> PHPickerViewController {
var config = PHPickerConfiguration()
config.filter = .images
config.selectionLimit = 1
let picker = PHPickerViewController(configuration: config)
picker.delegate = context.coordinator
return picker
}
func updateUIViewController(_ uiView: PHPickerViewController, context: Context) {
}
class Coordinator: NSObject, PHPickerViewControllerDelegate {
func picker(_ picker: PHPickerViewController, didFinishPicking results: [PHPickerResult]) {
for img in results {
if img.itemProvider.canLoadObject(ofClass: UIImage.self){
img.itemProvider.loadObject(ofClass: UIImage.self) { (image, err) in
guard let image = image as? UIImage else {return}
self.parent.image = image
self.parent.picker = false
}
} else {
print("error getting image")
}
}
}
var parent : PHPicker
init(parent1: PHPicker) {
parent = parent1
}
}
}
How to I enable the user to edit his image (cutting, changing size, and so on...)?
