使用示例：

    // 选择城市
      public function actionCity()
      {
        $parameters = '
          "requestType": 0
        ';
        $PortData = Interfaces::Connections('city/addresslist', true, Interfaces::Montage($parameters));
        $PortData = json_decode($PortData, true);
        // 热门城市
        $model['topList'] = isset($PortData['topList']) ? $PortData['topList']:[];
        // 所有城市
        $dataList = isset($PortData['topList']) ? $PortData['dataList']:[];
        $model['cityList'] = [];
        if(!empty($dataList)){
          foreach ($dataList as $key => $value) {
            $spell = mobile\models\SpellModel::encode($value['name']);
            $spell = mb_substr($spell , 0 , 1); 
            if(!empty($spell)) $model['cityList'][$spell][] = $value;
          }
          ksort($model['cityList']); //排序
        }
        return $this->render('city', [
          'model' => $model,
        ]);
      }

效果图如下：
