Swift中如何进行相机和相册的调用

发布时间:2024-04-12 15:59:20 来源:亿速云 阅读:304 作者:小樊 栏目:移动开发

在Swift中,可以使用UIImagePickerController类来调用相机和相册。以下是一个简单的示例代码,演示了如何调用相机和相册:

import UIKit

class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()
    }

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

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

    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
        if let pickedImage = info[UIImagePickerController.InfoKey.originalImage] as? UIImage {
            // 在此处处理选择的照片
        }
        dismiss(animated: true, completion: nil)
    }

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

}

在这个示例中,我们创建了一个ViewController类,并实现了UIImagePickerControllerDelegate和UINavigationControllerDelegate协议。我们在takePhoto和choosePhoto方法中分别调用相机和相册。在imagePickerController和imagePickerControllerDidCancel方法中,我们处理选取照片和取消选取照片的逻辑。
