I’ve just checked in a revision of my open source FMX TClipboard implementation that has an iOS backend. This supports the current rather than the FPC-based version of ‘Delphi for iOS’, however the Windows and OS X backends still compile with XE2 and above.
In essence, the new code wraps the native iOS clipboard API (UIPasteboard) and presents it in a fashion that closely follows the VCL clipboard interface, just like the existing Windows and OS X support did the same for desktop platforms. For some reason Apple in their wisdom decided to make the iOS clipboard API similar yet randomly different to the OS X one, so even though there’s not masses of code, it was a bit fiddly to implement. Anyhow, I’ve also knocked out a little demo similar to the previous desktop one:
Using (say) Photos, you can copy an image to the clipboard and paste it into the demo. Conversely, you can from the demo itself copy either just the text entered, just the image, both the text and the image as two representations of the same clipboard item, or both the text and image as a custom clipboard format. The ‘List Formats on Clipboard’ button, as its name implies, then lists the formats currently on the clipboard. This is what I get after copying an image from Photos on the iOS simulator:
Technically, the iOS clipboard, like the OS X one, can have multiple items, each with multiple representations. Since the multiple-item concept doesn’t exist on Windows (indeed, it didn’t exist on OS X originally either), my class is only concerned with the first item, which is what most applications only bother with anyhow.
If you want the code, the SVN URL for it and a few other pieces is the following:
