我正在尝试在ViewController上实现ImagePicker,但事实证明它在控制台上显示空白ImagePicker控制器和UIImagePickerController extension discovery failed with error: (null)
消息。
我不知道我在做什么错,也没有发现有关此事的信息。不过,我注意到的一件事是PickerView花费的时间太长而无法呈现。
与ImagePicker相关的代码如下:
private let imagePicker = UIImagePickerController()
private func setupImagePicker() {
imagePicker.sourceType = .photoLibrary
imagePicker.allowsEditing = false
imagePicker.delegate = self
imagePicker.mediaTypes = ["public.image"]
}
@objc private func launchImagePicker() {
let photos = PHPhotoLibrary.authorizationStatus()
if photos == .notDetermined {
PHPhotoLibrary.requestAuthorization({ [weak self] status in
DispatchQueue.main.async {
if status == .authorized, let picker = self?.imagePicker {
self?.present(picker, animated: true, completion: nil)
} else {
self?.present(URealtorUtils.getAlert(message: "You have to authorize photo library access in order to upload a photo"), animated: true, completion: nil)
}
}
})
} else if photos == .authorized {
present(imagePicker, animated: true, completion: nil)
}
}
extension MyController: UIImagePickerControllerDelegate, UINavigationControllerDelegate {
func imagePickerController(_ picker: UIImagePickerController,
didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey: Any]) {
if let image = info[UIImagePickerController.InfoKey.originalImage] as? UIImage {
self.viewModel.setPropertyImage(image)
}
dismiss(animated: true, completion: nil)
}
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
dismiss(animated: true, completion: nil)
}
}
这是在显示PickerView时得到的屏幕截图:
我检查了详细信息,并且您的实现没有问题。我还在这里检查了苹果的官方样品。https://developer.apple.com/documentation/uikit/uiimagepickercontroller/customizing_an_image_picker_controller结果相同!
最后,这是与iOS版本/模拟器有关的问题。我只希望你们不要在此浪费时间。继续前进。
谢谢。
