Since I recently updated my iPad Air to iOS 8 (big mistake), I noticed that I can’t copy some of the forum code. As usual, Apple screwed things up with their update because I have no problem copying any forum code on my iPad 1 running iOS 5. It seems I can copy small programs, but larger one just won’t select/copy. I managed to find a way to do it. If it won’t select for copy on a single tap, what works is a tap, tap slide. In other words, tap the screen then immediately tap and slide the second time. This will leave the up/down slider pins that can now be moved to select the code.
EDIT: Just an example, I can’t do a normal copy on Luatee’s “A present for everyone”. I have to do the tap, tap slide.
