Save image to app album with UIActivityViewController
I am using UIActivityViewController to share and save images in my app. Right now, images get stored in global Camera roll. I want to save it to app's own album. To do that, I had to exclude UIActivityTypeSaveToCameraRoll from UIActivityViewController and add my own custom SaveImageActivity. Now problem is that the activity comes at the last. How do I change the order to bring my custom UIActivity to the front? Similar queries show that this is not possible to do. How is Dropbox app able to do it then?
