1. 构造icheck指令

var app = angular.module('myApp', []);
app.directive('icheck', ['$timeout', '$parse', function($timeout, $parse) {    return {
      restrict: 'A',      require: '?ngModel',
      link: function(scope, element, attr, ngModel) {
        $timeout(function() {          var value = attr.value;        
          function update(checked) {            if(attr.type==='radio') { 
              ngModel.$setViewValue(value);
            } else {
              ngModel.$setViewValue(checked);
            }
          }
          
          $(element).iCheck({
            checkboxClass: attr.checkboxClass || 'icheckbox_square-grey',
            radioClass: attr.radioClass || 'iradio_square-grey'
          }).on('ifChanged', function(e) {            if ($(element).attr('type') === 'checkbox' && attr['ngModel']) {
                scope.$apply(function() {                    return ngModel.$setViewValue(e.target.checked);
                });
            }            if ($(element).attr('type') === 'radio' && attr['ngModel']) {                return scope.$apply(function() {                    return ngModel.$setViewValue(value);
                });
            }
          });
    
          scope.$watch(attr.ngChecked, function(checked) {            if(typeof checked === 'undefined') checked = !!ngModel.$viewValue;
            update(checked)
          }, true);
    
          scope.$watch(attr.ngModel, function(model) {
            $(element).iCheck('update');
          }, true);
          
        })
      }
    }
}]);

2. 声明数据模型

angular.module('myApp').controller(function($scope){
    $scope.sexList = [
        {
            id : 0,
            label : '男'
        },
        {
            id : 1,
            label : '女'
        },
        {
            id : 2,
            label : '其他'
        }
    ];    
    
    $scope.ruleList = [
        {
            id: 0,
            name : '信控'
        },
        {
            id: 1,
            name: '风控'
        },
        {
            id: 2,
            name: '客户经理'
        }
    ];
    
    $scope.selectSex = 0;   //选中的性别
    $scope.selectRule = {}  //选中的角色});

3. 使用指令

<div class="form-group">
    <label class="col-md-2 control-label">性别</label>
    <div class="col-md-3 padding-lr-empty">
        <div class="input-group">
            <!-- 横排是inline，竖排是list -->
            <div class="icheck-inline">
                <label ng-repeat="(index,item) in sexList">
                    <input type="radio" name="sex" for="sex"
                    ng-model="$parent.selectSex" ng-value="$index" icheck>{{item.label}}                </label>
            </div>
        </div>
        {{selectSex}}    </div>
    <label class="col-md-2 control-label">角色</label>
    <div class="col-md-3 padding-lr-empty">
        <div class="input-group">
            <div class="icheck-inlie">
                <label ng-repeat="item in ruleList" style="margin-right: 12px;">
                    <input type="checkbox" icheck 
                        ng-model="selectRule[item.id]" name="rule" for="rule">{{item.name}}                </label>
            </div>
        </div>
        {{selectRule}}    </div></div>
