ios - Get NSDate to say "XX time ago" that article was published -


this question has answer here:

i have date article published, need how long ago published in relation current time.

so if article published @ 8:45am, , 9:45am on same day, need able have uilabel says "1 hr ago".

currently, getting date formatted date "may 5, 2013 5:35pm":

- (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath {         feed *feedlocal = [headlinesarray objectatindex:indexpath.row];         nsdateformatter *df = [[nsdateformatter alloc] init];         [df setdateformat:@"mmmm d, yyyy h:mma"];         nsstring *datestring = [df stringfromdate:feedlocal.published];         cell.publishedlabel.text = datestring; }

how convert "1 hr ago"? thanks!

edit

here current method have @ least time ago:

-(nsstring *)timeago {     nsdate *todaydate = [nsdate date];      double ti = [self timeintervalsincedate:todaydate];     ti = ti * -1;     if (ti < 1) {         return @"1s";     } else if (ti < 60) {         return @"1m";     } else if (ti < 3600) {         int diff = round(ti / 60);         return [nsstring stringwithformat:@"%dm", diff];     } else if (ti < 86400) {         int diff = round(ti / 60 / 60);         return[nsstring stringwithformat:@"%dh", diff];     } else if (ti < 2629743) {         int diff = round(ti / 60 / 60 / 24);         return[nsstring stringwithformat:@"%dd", diff];     } else if (ti < 31556926) {         int diff = round(ti / 60 / 60 / 24 / 30);         return [nsstring stringwithformat:@"%dmo", diff];     } else {         int diff = round(ti / 60 / 60 / 24 / 30 / 12);         return [nsstring stringwithformat:@"%dy", diff];     } }

im not sure timeago method of, here solution assuming in same viewcontroller tableview:cellforrowatindexpath. if can clarify method of may able modify , more.

first change timeago take in date , comparison on it.

-(nsstring *)timesincepublished:(nsdate *)publicationdate  {     double ti = [publicationdate timeintervalsincenow];

everything else should same in above method.

- (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath {     feed *feedlocal = [headlinesarray objectatindex:indexpath.row];     nsstring *datestring = [self timesincepublished:feedlocal.published];     cell.publishedlabel.text = datestring; }

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...

i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
