I want to pick an image with PHPickerViewController. But this causes to memory link. Can anyone help me with this issue?(
I created ImagePickerManager and I'm using it on ViewController below.
P.s: I didn't get a leak when writing the same code with UIImagePickerViewController.
import Foundation
import Photos
import PhotosUI
class ImagePickerManager: NSObject {
// MARK: Variables
var accessType: PHAccessLevel = .addOnly
var pickerViewController = PHPickerViewController(configuration: PHPickerConfiguration())
//var viewController: UIViewController?
var pickImageCallback : ((UIImage) -> ())?;
// MARK: Init
override init() {
super.init()
setupPhotoPicker()
setupPhotoLibrary(accessType)
}
// convenience init(
// viewController: UIViewController,
// accessType: PHAccessLevel = .addOnly) {
// self.init()
//
// self.viewController = viewController
// setupPhotoLibrary(accessType)
// setupPhotoPicker()
// }
// MARK: Setup
private func setupPhotoLibrary(_ accessType: PHAccessLevel) {
self.checkAuthorizationStatusForPhotoLibrary()
self.accessType = accessType
}
private func setupPhotoPicker() {
pickerViewController.delegate = self
}
// MARK: Present PickerController
func presentPHPicker(_ viewContr: UIViewController,_ callback: @escaping ((UIImage) -> ())) {
pickImageCallback = callback
// self.viewController = viewContr
viewContr.present(pickerViewController, animated: true)
}
// MARK: Checking status of Photo library access
func checkAuthorizationStatusForPhotoLibrary() {
switch PHPhotoLibrary.authorizationStatus(for: accessType) {
case .authorized: break
case .notDetermined:
self.requestAuthorizationForPhotoLibrary()
case .denied:
self.showAccessDeniedMessage()
default: return
}
}
// MARK: Request to Access Photo Library
func requestAuthorizationForPhotoLibrary () {
PHPhotoLibrary.requestAuthorization(for: accessType) { status in
switch status {
case .authorized:
print("Access granted")
case .denied: break
case .notDetermined: break
default: return
}
}
}
// MARK: Access Denied to do action
private func showAccessDeniedMessage() {
print("\n ShowAccessDeniedMessage \n")
}
}
// MARK: - PHPickerViewControllerDelegate
extension ImagePickerManager: PHPickerViewControllerDelegate, UINavigationControllerDelegate {
func picker(_ picker: PHPickerViewController, didFinishPicking results: [PHPickerResult]) {
picker.dismiss(animated: true, completion: nil)
for result in results {
result.itemProvider.loadObject(ofClass: UIImage.self, completionHandler: { (object, error) in
if let image = object as? UIImage {
// DispatchQueue.main.async {
// Use UIImage
self.pickImageCallback?(image)
// }
}
})
}
}
}
/// -------- ViewController
let imageManager = ImagePickerManager()
@objc func pressedButton() {
imageManager.presentPHPicker(self) { image in
print("something...")
}
}
