iphone - How to filter array of NSDictionary for key separated by comma -


i have array of nsdictionary.nsdictionary has key named multiple_image key contain string separated ,.

i want set of array contain 123.png multiple_images key. can 1 show me how using nspredicate or without predicate.

//array  {     image = "<uiimage: 0xf72df30>";     active = yes;     "admin_id" = 169;     "category_id" = 32;     "chef_id" = 175;     descr = "cool tea cool down mind.";     id = 110;     "multiple_images" = "jellyfish.jpg,345.png";     name = "southern sweet ice tea";     price = 160;     rating = 3;     selected = 0;     "subcat_id" = 23;     "tag_id" = 45;     "tax_id" = 10;     "tax_value" = "12.00"; },     {     image = "<uiimage: 0xf72ebd0>";     active = yes;     "admin_id" = 169;     "category_id" = 31;     "chef_id" = 175;     descr = "ingredients almonds or cashews. no hydrogenated stuff, no weirdo ingredients";     id = 107;     "multiple_images" = "jellyfish.jpg,123.png";     name = "butter chicken";     price = 300;     rating = 3;     selected = 0;     "subcat_id" = 24;     "tag_id" = 43;     "tax_id" = 9;     "tax_value" = "0.00"; },     {     image = "<uiimage: 0xf72f870>";     active = yes;     "admin_id" = 169;     "category_id" = 31;     "chef_id" = 173;     descr = "raw vegetables  including carrots, cucumbers.";     id = 100;     "multiple_images" = "jellyfish.jpg,shake.png,";     name = salads;     price = 50;     rating = 3;     selected = 0;     "subcat_id" = 22;     "tag_id" = 44;     "tax_id" = 9;     "tax_value" = "0.00"; }

using predicates,

[array filteredarrayusingpredicate:[nspredicate predicatewithformat:@"multiple_images contains '123'"]];

using predicates, blocks

    nsarray *filtered = [test filteredarrayusingpredicate:[nspredicate predicatewithblock:     ^bool(nsdictionary *evaluatedobject, nsdictionary * bindings) {         nsstring *key = @"123";         return ([evaluatedobject[@"multiple_images"] rangeofstring:key].location != nsnotfound);     }]];

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...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
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...
