问题 I'm trying to figure out a way to have my iOS app save a screenshot to the Camera Roll and then pop up an alert to tell the user that the screenshot was saved successfully. The only way I can think to do this would be with some form of an if/else loop (as you'll see in my pseudocode comments below), but I can't think of any syntax to work with the UIImageWriteToSavedPhotosAlbum function from UIKit. I've come across suggestions that say to use completionSelector and completionTarget on Apple's

You can then use the script to do whatever you want with the new files. This article at TUAW includes an example of uploading files to a web
