问题描述

我正在尝试使用 UIImagePickerController.它曾经工作正常，但突然停止工作.

I'm trying to use UIImagePickerController. It used to work fine but suddenly stopped working.

目前，我的结果不一致(有时有效，有时无效).以下是与 UIIMagePickerController 相关的方法.

Currently, I have inconsistent results(it sometimes works but sometimes doesn't). Here are methods related to UIIMagePickerController.

怎么了?

 @IBAction func uploadImageTapped(_ sender: UIButton) {

    let pickerView = UIImagePickerController()

    // Set cameraroll sor chooseing a photo
    // choose '.camera' if you want to take the picture
    pickerView.delegate = self
    pickerView.sourceType = .photoLibrary

    self.present(pickerView, animated: true, completion: nil)
}
.
.
.
extension RetailerProfileViewController: UIImagePickerControllerDelegate, UINavigationControllerDelegate {

// method that will be called when user choose the pic
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
    // get the info of photo
    let image = info[.originalImage] as! UIImage
    // show it
    storeImage.image = image

    // dismiss the photo library
    self.dismiss(animated: true)
}

}

我检查了详细信息，您的实施没有问题.我还在这里检查了苹果的官方样本.https://developer.apple.com/documentation/uikit/uiimagepickercontroller/customizing_an_image_picker_controller 同样的结果！

I checked the details, and there are no issues in your implementation. I also checked the apple's official sample here. https://developer.apple.com/documentation/uikit/uiimagepickercontroller/customizing_an_image_picker_controller Same result!

最后，这是一个与 iOS 模拟器(版本 11.3.1)相关的问题.我只是希望你们不要在这上面浪费时间.继续前进.

Finally, this is an issue related to iOS Simulators(version 11.3.1). I just want you guys not wasting time on this. Move ahead.
