Question

在其他演示中效果很好，但是在我的项目中崩溃了。我用Google搜索“ CAMPreviewViewController”，但什么也没找到

library(tidyr)
separate(df, V1, c("V1", "V2", "V3"), " ")

#### OUTPUT ####

尝试这个

    var imagePicker: UIImagePickerController!

 @IBAction func takePhotoAction(_ sender: UIButton) {
        imagePicker =  UIImagePickerController()
        imagePicker.delegate = self
        imagePicker.sourceType = .camera
        present(imagePicker, animated: true, completion: nil)
    }

Add This to class as delegates 

 UINavigationControllerDelegate, UIImagePickerControllerDelegate

在iOS 13中使用UIImagePickerController时崩溃
