objective c - Reproducing the Tumblr Tagging Effect in iOS -


i'm stumped how it.

first, view looks this:
starting image

next, tap in tags bar (i assume modified uitextfield placeholder image) , tags bar animates top of view. seen in photo below:
tags tapped image

you can add tag typing word or series of words , clicking return on keyboard. once this, bubble encompasses tag , shows on tag bar.

once have finished, clicked "done" button , tags bar animates downward original position, along tags in bar, shown below:
final position image

i have several questions:

  1. how animate tags bar , tags field downward, , how animate tags field upward (i assume coreanimation - have no experience it. group views this, or one-by-one)
  2. how produce "tagging affect" in uitextview/field?

my 1 theory group bottom 2 views uiview, , animate whole. tagging process, don't bubbles (i have no idea on how this), allow single-word tags , parse textview , insert words manually bar. think may produce bit of lagging affect though.

i finished creating pretty versatile class should need. can find here: rolemodel/rmstokenview.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

Image
