ios - UICollectionView allow user to choose cell colour -


i making app tracking points, user can add new cell uicollectionview name , default of 0 points.

i don't have issue such not sure on how accomplish task. when user creates new cell want them able choose color of cell 4 predefined options.

if explain me how accomplish make week.

(i tried add images show views give better understanding don't have enough rep)

edit : perhaps should of mentioned first ios project @ work , im super noob, if explain me steps neccessary gets work great.

this method gets called when user creates new cell. (this contained in class sql methods together)

+(void) writedata:(nsstring*)name {  [self databaseinit];  if (sqlite3_open(dbpath, &peopledb ) == sqlite_ok) {      nsstring *insertsql = [nsstring stringwithformat:@"insert people (name, points) values (\"%@\", \"%i\")",name, 0];       const char *insert_stmt = [insertsql utf8string];     sqlite3_prepare_v2( peopledb, insert_stmt,-1, &statement, null);     if (sqlite3_step(statement) == sqlite_done)     {         nslog(@"added successfully");      }     else {         nslog(@"%s sqlite_error '%s' (%1d)", __function__, sqlite3_errmsg(peopledb), sqlite3_errcode(peopledb));     }     sqlite3_finalize(statement);     sqlite3_close(peopledb); }

}

then in viewcontroller.m (main view)

- (void)viewdidload { [super viewdidload]; uinib *cellnib = [uinib nibwithnibname:@"custombrowniecell" bundle:nil]; [self.collectionview registernib:cellnib forcellwithreuseidentifier:@"cbcell"]; people2 = [[nsmutablearray alloc] init]; [databaseclass createdb]; people2 = [databaseclass getdata];

}

-(uicollectionviewcell *)collectionview:(uicollectionview *)collectionview cellforitematindexpath:(nsindexpath *)indexpath{  static nsstring *cellidentifier = @"cbcell"; customcell *cell = (customcell *)[self.collectionview dequeuereusablecellwithreuseidentifier:cellidentifier                                                                                     forindexpath:indexpath]; personobject *a = (personobject*)[people2 objectatindex:indexpath.row]; cell.namelabel.text = a.name; cell.pointslabel.text = [nsstring stringwithformat:@"%i", a.points]; cell.idlabel.text = [nsstring stringwithformat:@"%i", a.id];  return cell;

}

you set flag on whatever object (if any) behind cell, , in cellforitematindexpath set background color based on flag.

how give user choice depend on how "add cell" functionality implemented. if show code, more specific or maybe give example.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
