【问题描述】：

为了开发应用，我设置了一个带有.savedPhotosAlbum 的 UIImagePicker 作为源类型。

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 上试用我的应用程序，所以我改变了这个：

imagePicker.sourceType = .savedPhotosAlbum

到

imagePicker.sourceType = UIImagePickerControllerSourceType.camera

我已经添加了我的info.plist

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

但是当我尝试拍照时，它一直显示我的相册，这就是问题所在。我希望能够从手机的相机中拍照。

【问题讨论】：

您需要添加更多上下文，因此将代码放在您正在检查设备并显示picker的位置
@Santosh 第一次发布有关 IOS 的帖子抱歉，我已经添加了所有我所拥有的

标签： ios swift camera uiimagepickercontroller

【解决方案1】：

你需要输入这段代码

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 的委托方法中，该方法在选择图像或获取图像后被调用。

非常感谢您的解决方案和解释！
