Swift，相机图像不 return

Question

请原谅我的初学者问题。我加载相机并拍照，但似乎从未调用覆盖函数 imagePickerController，所以我永远无法将照片设置到 imageView，代码如下。任何想法？谢谢

@IBAction func takePhotoClick(_ sender: AnyObject) {
    imagePicker =  UIImagePickerController()
    imagePicker.delegate = self
    imagePicker.sourceType = .camera

    present(imagePicker, animated: true, completion: nil)

}    
var imagePicker: UIImagePickerController!

public func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
        imagePicker.dismiss(animated: true, completion: nil)

        photoImageView.image = info[UIImagePickerControllerOriginalImage] as? UIImage




}

Answer 1

You need to ask the use permission before access the user private data like contact number, photos , location , calendar , etc. in iOS 10 Apple is extending the scope of privacy control. You have to declare in Info.plist file access of any private data.

Which framework have privacy key in Info.plist :

Calendar , Contact , Reminder , Photo , Bluetooth Sharing , Microphone , Camera , Location , Heath , HomeKit , Media Library , Motion , CallKit , Speech Recognition , SiriKit , TV Provider.

有关详细信息，请参阅 this

检查一次您是否在 plist 中添加了以下信息

然后像

一样调用委托方法

 func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
if let image = info[UIImagePickerControllerOriginalImage] as? UIImage  {
    photoImageView.image = image
}

picker.dismiss(animated: true, completion: nil);
}
