ios - 提示 iOS 用户选择要由应用程序处理的 JPEG

Question

我已经在 Android 中完成了此操作，但似乎找不到有关在 iOS 中执行此操作的任何信息。基本上:

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("image/JPEG");
Intent i = Intent.createChooser(intent, "File");
startActivityForResult(i, CHOOSE_FILE_REQUESTCODE);

然后

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // Check which request we're responding to
    if (requestCode == CHOOSE_FILE_REQUESTCODE) {
        // Make sure the request was successful
        if (resultCode == RESULT_OK) {
            // The user picked a contact.
            // The Intent's data Uri identifies which contact was selected.

            // Do something with the contact here (bigger example below)
        }
    }
}

相应的术语和示例代码是什么/在哪里？

iOS 中的 UIImagePickerController View Controller 是允许用户从媒体库中选择图片的标准方法。有关此问题的 Apple 文档可在 UIImagePickerController. 处获取。还有一个很好的教程展示了如何使用 UIImagePickerController 在 Picking images with UIImagePickerController in Swift 5 .
