在UIImagePickerController类型的视频模式下拍照,可以通过以下步骤实现:
以下是一个示例代码:
import UIKit
class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
override func viewDidLoad() {
super.viewDidLoad()
}
// 拍照按钮点击事件
@IBAction func takePhotoButtonTapped(_ sender: UIButton) {
let imagePicker = UIImagePickerController()
imagePicker.sourceType = .camera
imagePicker.mediaTypes = [kUTTypeImage as String]
imagePicker.allowsEditing = false
imagePicker.cameraCaptureMode = .photo
imagePicker.delegate = self
present(imagePicker, animated: true, completion: nil)
}
// 拍照完成后的处理
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
if let image = info[.originalImage] as? UIImage {
// 处理拍摄的照片
// ...
}
picker.dismiss(animated: true, completion: nil)
}
// 用户取消拍照
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
picker.dismiss(animated: true, completion: nil)
}
}
在这个示例中,我们创建了一个UIViewController的子类,并在其中实现了UIImagePickerControllerDelegate和UINavigationControllerDelegate协议。通过点击拍照按钮,我们创建了一个UIImagePickerController实例,并设置其相关属性,然后通过present方法展示出来。当用户拍照完成后,会调用imagePickerController:didFinishPickingMediaWithInfo:方法,我们可以在该方法中获取到拍摄的照片,并进行后续处理。如果用户取消拍照,则会调用imagePickerControllerDidCancel:方法,我们可以在该方法中进行相应的处理。
