Also provided is a custom URL scheme to annotate the local clipboard. You will need Xcode to compile the app; see the start of the generated C file for instructions. If Xcode runs out of space, try using --data-driven. The --ios option has been deprecated because it relies on a component called UIWebView which Apple have deprecated. Since I do not have the necessary equipment to test a rewrite with WKWebView, nor am I aware of Apple's App Store having ever accepted an app from an Annogen user, I do not now plan to invest time in migrating the code from UIWebView to WKWebView, and if I ever find out Apple removed UIWebView altogether then I will probably delete the --ios option (unless somebody sends me a patch to fix it).")
