角度指令中的Google自动填充不适用于移动版Safari

Question

我有一个角度指令，用于侦听谷歌地方'place_changed'事件。代码在桌面浏览器中运行良好。

但是，它不适用于iOS7中的移动Safari（未测试旧版本）。点击一个位置似乎没有触发place_changed事件，并且输入字段没有填充位置值。

是否还有其他一些我应该触发的事件，在听？

angular.module('app').directive('googlePlace', function (Location) {
    return {
        restrict: 'A',
        require: 'ngModel',
        link: function ($scope, element, attributes, model) {

            var autocomplete = new google.maps.places.Autocomplete(element[0], {types: ['(cities)']});
            google.maps.event.addListener(autocomplete, 'place_changed', function () {



                    if (autocomplete.getPlace()){
                        var googlePlace = autocomplete.getPlace();
                        $scope.googlePlace = googlePlace;
                        Location.setGooglePlace(googlePlace);

                        var location = googlePlace.address_components[0].long_name + ', ';
                        if (googlePlace.address_components.length === 2) {
                            location = location + googlePlace.address_components[1].long_name;
                        } else if (googlePlace.address_components.length === 3) {
                            location = location + googlePlace.address_components[2].long_name;
                        } else if (googlePlace.address_components[3].short_name === 'US') {
                            location = location + googlePlace.address_components[2].short_name;
                        } else {
                            location = location + googlePlace.address_components[3].long_name;
                        }

                        $scope.displayLocation = location;

                        $scope.$apply(function () {
                            setTimeout(function(){
                                model.$setViewValue($scope.displayLocation);
                                model.$setValidity(element.name, true);
                                element.val($scope.displayLocation);
                            }, 100);

                        });
                    } else {
                        $scope.googlePlace = null;
                        $scope.displayLocation = null;
                        model.$setViewValue($scope.displayLocation);
                        model.$setValidity(element.name, true);
                        element.val($scope.displayLocation);
                    }

                });


            element.on('blur', function () {

                setTimeout(function(){
                    if (attributes.required && !$scope.googlePlace){
                        model.$setValidity(element.name, false);
                    } else if (element.val() && !$scope.googlePlace){
                        model.$setValidity(element.name, false);
                    } else if (!element.val()){
                        Location.setGooglePlace(null);
                        model.$setValidity(element.name, true);
                    } else{
                        model.$setViewValue($scope.displayLocation);
                        model.$setValidity(element.name, true);
                        element.val($scope.displayLocation);
                    }
                }, 300); // this seems to matter even though 0
            });


            element.on('keypress', function (e) {
                $scope.googlePlace = null;
                Location.setGooglePlace(null);

                if (e.which === 13) {
                    google.maps.event.trigger(autocomplete, 'place_changed');
                }

            });

        }
    };
});
