I am writing an iOS app and I just want to make sure I call it the appropriate thing. I'm used to clipboard but apparently Apple calls it a pasteboard on iOS. Googling doesn't turn anything specific up.
I see the class is called UIPasteboard but I'm just looking to verify the literature/end user communication uses this term as well.
Yes, UIPasteboard is the clipboard (or the service behind the copy and paste feature). Most users are unlikely to know what either pasteboard or clipboard means. If you're describing the feature you should probably use the simple 'copy & paste' terminology.
