ios - UIImagePicker源类型不想更改

为了开发一个应用程序，我设置了一个UIImagePicker，它的源类型是.savedPhotosAlbum。

import UIKit

class PictureViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

    /////////////////// OUTLETS ////////////////////
    ///////////////// PROPERTIES ///////////////////
    var imagePicker = UIImagePickerController()

override func viewDidLoad() {
        super.viewDidLoad()

        imagePicker.delegate = self

    }

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
        // Where do we want our photos from and we don't want edited photos
        imagePicker.allowsEditing = false
        imagePicker.sourceType = UIImagePickerControllerSourceType.camera
        imagePicker.cameraCaptureMode = .photo
        imagePicker.modalPresentationStyle = .fullScreen

        // Let's take the image from the picker
        let image = info[UIImagePickerControllerOriginalImage] as! UIImage
        snapImage.image = image

        // When the user picks a picture, disabling the background color of the UIImageView
        snapImage.backgroundColor = UIColor.clear

        // Closing the image picker
        imagePicker.dismiss(animated: true, completion: nil)
    }

    @IBAction func cameraTapped(_ sender: Any) {
        present(imagePicker, animated: true, completion: nil)
    }

现在我的应用程序已经完成，我想在我的Iphone上尝试我的应用程序，所以我更改了以下内容：

imagePicker.sourceType = .savedPhotosAlbum

到

imagePicker.sourceType = UIImagePickerControllerSourceType.camera

我在我的info.plist中添加了

<key>NSCameraUsageDescription</key>
    <string>We want to access your camera to ...</string>

但当我试着拍照时，它总是给我看我的相册，这就是问题所在。
我想用手机的摄像头拍张照片。

最佳答案

你需要把这个密码

imagePicker.allowsEditing = false
imagePicker.sourceType = UIImagePickerControllerSourceType.camera
imagePicker.cameraCaptureMode = .photo
imagePicker.modalPresentationStyle = .fullScreen

在viewDidLoad或cameraTapped中
问题-现在您将此代码放在UIImagePicker的delegate方法中，该方法在选择图像或拍摄图像后调用。
