在iOS 13中，UIImagePickerController不返回实时照片

import Photos

// 在UIImagePickerController的代理方法中获取PHAsset对象
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
    if let asset = info[.phAsset] as? PHAsset {
        // 使用PHImageManager获取照片的实时数据
        let imageManager = PHImageManager.default()
        let requestOptions = PHImageRequestOptions()
        requestOptions.isSynchronous = true
        requestOptions.deliveryMode = .highQualityFormat
        
        imageManager.requestImage(for: asset, targetSize: CGSize(width: 1000, height: 1000), contentMode: .aspectFit, options: requestOptions) { (image, _) in
            // 在这里处理获取到的实时照片
            if let image = image {
                // 处理照片
            }
        }
    }
    
    picker.dismiss(animated: true, completion: nil)
}
