如何将刚选择或拍摄的照片设置为myPhoto?您可以从 UIImagePickerControllerDelegate函数。你必须把它设置好 UIImagePickerController(picker)实例的委托 请求许可 在访问应用程序之前,应用程序必须获得用户的许可 照相机/已保存的照片。应用程序应向用户显示一条消息 解释为什么需要摄像头或照片库访问。你可以 通过设置nsCamerauseControlation和 应用程序的Info.plist文件中的NSPhotoLibraryUsageDescription密钥 这肯定会奏效
imagePicker.delegate = self
extension StackOverflowViewController: UIImagePickerControllerDelegate, UINavigationControllerDelegate {
func imagePickerController( picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
var selectedImage: UIImage?
if let editedImage = info[.editedImage] as? UIImage {
selectedImage = editedImage
self.imgView.image = selectedImage!
} else if let originalImage = info[.originalImage] as? UIImage {
selectedImage = originalImage
self.imgView.image = selectedImage!
picker.dismiss(animated: true, completion: nil)
}
}
func imagePickerControllerDidCancel( picker: UIImagePickerController) {
picker.dismiss(animated: true) {
// Further logic to perform
}
}
}
