ios - PrepareForSegue issues -


i have 3 methods below using storyboard have "segue" connect "view movie info" button next view. identifier "web"

when click on button call method: (ibaction)synopsis:(id)sender method calls -> (void)fetchemovie:(nsdata *)responsedata , should go (void)prepareforsegue:(uistoryboardsegue *)segue sender:(id)jason

on prepareforsegue method put nsslog on "jsonsendetasparaminperformsegue" , 2 logs

1: uiroundedrectbutton: 0x9595c60; frame = (11 322; 298 44); opaque = no; autoresize = tm+bm; layer = calayer: 0x9595d30

2->my json results ( expect )

and below this: 2013-05-09 18:55:06.185 drigo[840:c07] nested push animation can result in corrupted navigation bar unbalanced calls begin/end appearance transitions . finishing navigation transition in unexpected state. navigation bar subview tree might corrupted.

i need 1 of values json , pass next view

the methods below.. please help.. i've been stuck couple of days on this

- (ibaction)synopsis:(id)sender {     nsstring *urlstring = [nsstring stringwithformat:@"http://api.themoviedb.org/3/movie/%@?api_key=34eb86f3b94de2676e8d3007b5ce1993",movieid];     dispatch_async(kbgqueue, ^{     nsurl *url = [nsurl urlwithstring:urlstring];     nsdata* data = [nsdata datawithcontentsofurl:url];     [self performselectoronmainthread:@selector(fetchemovie:)withobject:data waituntildone:no];     }); }  - (void)fetchemovie:(nsdata *)responsedata {     nserror* error;     nsdictionary* json = [nsjsonserialization jsonobjectwithdata:responsedata  options:kniloptions error:&error];     news = [nsjsonserialization jsonobjectwithdata:responsedata  options:kniloptions error:&error];     [self performseguewithidentifier:@"web" sender:news]; }  - (void)prepareforsegue:(uistoryboardsegue *)segue sender:(id)jason {     nserror* error;     nsdictionary *jsonsendetasparaminperformsegue = (nsdictionary*)jason;     nslog(@"%@",jsonsendetasparaminperformsegue);     //webviewcontroller *targetvc = (webviewcontroller*)segue.destinationviewcontroller;     //targetvc.newsarticles = jsonsendetasparaminperformsegue; }

you should connect segue source viewcontroller destination viewcontroller, don't connect button.

if connect button, when click button, performs segue(the sender button), in code call perform segue again, why it's wrong.

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...
