问题 I'm implementing drag and drop in my app. One of the main screens where drag and drop will be applied (mostly drop) is in a UITextView . I've added a drop interaction to this UITextView with the following code: let dropInteraction = UIDropInteraction(delegate: self) inputTextView.addInteraction(dropInteraction) By doing so I now accept drops in it.

问题 I'm playing with cdk Drag and Drop cause I need it to create a POC for work. I started with this code from the documentation website. I saw that every time I drag an element outside its list, said element is hidden until I drop it in the same list or in another one.

问题 I know very well that you are not allowed to upload a whole folder via drag and drop. The problem is, how can I tell if someone tries to do it?

I have tested this in Chrome and Safari and Firefox on Mac OS X and Windows. Depending on the browser and OS, I get slightly different results. Sometimes it succeeds in uploading
