I have a working code where I copy an image to UIPasteboard, but I cannot find a way to implement the PASTE functionality programmatically. Any idea or tip?
The following piece of code might work. Make sure you are testing on the device.
let image = UIImage(named: "person.png")
UIPasteboard.generalPasteboard().image = image;
based on the comment, you can do it as follows. I am putting here the objective-c code, I hope you could get the idea then convert it to the swift.
NSData* pasteData = [[UIPasteboard generalPasteboard] dataForPasteboardType:(NSString*)kUTTypeJPEG];
