使用此代碼爲我的代碼swift 3.0，

@IBAction func selectPhoto(_ sender: UIButton) { 
    var picker = UIImagePickerController() 
    picker.delegate = self 
    picker.allowsEditing = true 
    picker.sourceType = .photoLibrary 
    self.present(picker, animated: true, completion: { _ in }) 
} 

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [AnyHashable: Any]) { 
    var chosenImage = info[UIImagePickerControllerEditedImage] 
    self.imageView!.image! = chosenImage 
    picker.dismiss(animated: true, completion: { _ in }) 
} 

func imagePickerControllerDidCancel(_ picker: UIImagePickerController) { 
    picker.dismiss(animated: true, completion: { _ in }) 
}

您需要在圖像視圖的屬性編輯器中單擊「用戶交互已啓用」複選框。 Screenshot。從本質上講，這個錯誤「添加膳食照片」部分源於缺少的指令＃12：

在屬性檢查器中，找到互動領域，並選擇用戶交互啓用複選框。您稍後需要使用此功能才能讓用戶與圖片視圖進行互動。
