titanium listView dynamic data binding -


sdk: 3.5.1

i'm not familiar listview mechanics. i'm trying understand how apply json data values item template's bound properties.

i start mapping data

//example  var data = ({data:json-data, index:'label'});  var _data = _.map(data, function(item, index) {     return {         properties: {             categorylabel: index,             data: item          }     } });

i want bind list

$.activitydetailslist.sections[0].setitems(_data);

in view have

<listview defaultitemtemplate="activitydetailslistitemtemplate" id="activitydetailslist">   <templates>     <itemtemplate name="activitydetailslistitemtemplate">       <label bindid="categorylabel" class="rowtitle" id="categorylabel"/>       <view bindid="rightspacer" id="rightspacer">         <imageview bindid="arrowimage" id="arrowimage"/>       </view>     </itemtemplate>   </templates>  <listsection id="activitydetailslistsection">     <listitem template='activitydetailslistitemtemplate'/>   </listsection> </listview>

when iterate through 5 elements, blank rows corresponding arrows.

here's question: how categorylabel text values display? have define in template? part isn't clear me. thought binding data template enough. apparently not.

what worked me:

view xml

<alloy>     <window class="container">         <listview defaultitemtemplate="dailyactivitiestemplate" id="activitylist" top="30">             <templates>                 <itemtemplate name="dailyactivitiestemplate">                     <view id="dailyactivities">                         <view class="row" id="fundrow">                             <label class="rowtitle" id="fund" text="fund: "/>                             <label bindid="fund" class="rowvalue" id="fund"/>                         </view>                         <view class="row" id="amountrow">                             <label class="rowtitle" id="amount" text="amount: "/>                             <label bindid="amount" class="rowvalue" id="amount"/>                         </view>                         <view class="row" id="unitsrow">                             <label class="rowtitle" id="units" text="units: "/>                             <label bindid="units" class="rowvalue" id="units"/>                         </view>                         <view class="row" id="sourcerow">                             <label class="rowtitle" id="source" text="source: "/>                             <label bindid="source" class="rowvalue" id="source"/>                         </view>                         <view class="row" id="unitvaluerow">                             <label class="rowtitle" id="unitvalue" text="unit value: "/>                             <label bindid="unitvalue" class="rowvalue" id="unitvalue"/>                         </view>                     </view>                 </itemtemplate>             </templates>             <listsection>                 <listitem template="dailyactivitiestemplate"/>             </listsection>         </listview>     </window> </alloy>

controller:

var items = [];  _.map(_.first(activities), function(element, key) {      if (moment(new date(key)).isvalid()) {          _.each(element, function(item, key) {             items.push({                 fund: {                     text: item.fund                 },                 amount: {                     text: item.amount                 },                 units: {                     text: item.units                 },                 source: {                     text: item.source                 },                 unitvalue: {                     text: item.unitvalue                 }             });          });     }  }); $.activitylist.sections[0].setitems(items);

the important point me didn't need properties:{} parent. confused me. had data in view, needed style tss file.

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
