I have problem with UIActivity function
The first, I create 3 activity items: activityDownload,activityTrash,activityMove. And add to UIActivityViewController
And then, when I present UIActivityViewController which includes 3 items above. OK, no problem here.
Then, when I click button More, and sort items, ex, I move "Move" button to the top,
After click "Done" button, I don't know why Download, Trash items was lost?
Move items only display in AirDrop menu view
