ionic下拉加载自动触发

ionic提供的下拉加载，是要滑动去下拉加载，没有提供api自动触发下拉加载，比如刚进页面，或者切换tab时想触发一次下拉加载。

　　添加如下service:

　　

angular.module('YourApp').service('utilities', function() {

    this.triggerScrollViewPullToRefresh = function (scrollView) {
        scrollView.__publish(
            scrollView.__scrollLeft, -scrollView.__refreshHeight,
            scrollView.__zoomLevel, true);

        var d = new Date();

        scrollView.refreshStartTime = d.getTime();

        scrollView.__refreshActive = true;
        scrollView.__refreshHidden = false;
        if (scrollView.__refreshShow) {
            scrollView.__refreshShow();
        }
        if (scrollView.__refreshActivate) {
            scrollView.__refreshActivate();
        }
        if (scrollView.__refreshStart) {
            scrollView.__refreshStart();
        }
    }
});

然后在你的controller里添加方法：

　　

angular.module('YourApp').controller('YourController',
  function($scope, $ionicScrollDelegate, utilities) {
    $scope.someFunc = function() {
      // scrollerHandle should be the delegate-handle set on the scrollview
      $scope.scrollDelegate = $ionicScrollDelegate.$getByHandle('scrollerHandle');
      utilities.triggerScrollViewPullToRefresh($scope.scrollDelegate.getScrollView());
    };
  });

只要在你想触发的地方调用$scope.someFunc 就可以触发下拉刷新
