android - 类型错误 : Cannot read property 'getPictures' of undefined

Question

这是一个 ionic 应用程序，在同一个 Controller 中具有 $cordovaImagePicker 和 $cordovaCamera 功能，并且都从同一个 reservation.html 调用这是 Controller 定义:

.controller('AppCtrl', ['$scope', '$timeout', '$ionicModal', '$localStorage', '$cordovaCamera', '$ionicPlatform', '$cordovaImagePicker', function($scope, $timeout, $ionicModal, $localStorage, $cordovaCamera, $ionicPlatform, $cordovaImagePicker){

我使用ionic plugin add cordova-plugin-imagepicker安装了$cordovaImagePicker，使用ionic plugin add cordova-plugin-camera安装了$cordovaCamera

这是 Controller 代码:

$ionicPlatform.ready(function() {
            var options1 = {
                quality: 50,
                destinationType: Camera.DestinationType.DATA_URL,
                sourceType: Camera.PictureSourceType.CAMERA,
                allowEdit: true,
                encodingType: Camera.EncodingType.JPEG,
                targetWidth: 100,
                targetHeight: 100,
                popoverOptions: CameraPopoverOptions,
                saveToPhotoAlbum: false
            };

            $scope.takePicture = function() {
                $cordovaCamera.getPicture(options1).then(function(imageData) {
                    $scope.registration.imgSrc = "data:image/jpeg;base64," + imageData;
                }, function(err) {
                    console.log(err);
                });

                $scope.registerform.show();
            };

            var options2 = {
                maximumImagesCount: 1,
                width: 800,
                height: 800,
                quality: 80
            };
            $scope.getPicture = function() {
                $cordovaImagePicker.getPictures(options2).then(function (results) {
                    for (var i = 0; i < results.length; i++) {
                        console.log('Image URI: ' + results[i]);
                        $scope.registration.imgSrc = results[i];
                    }
                }, function(error) {
                    // error getting photos
                    console.log(error);
                });
            };
        });
    }])

我正在 Android 5 手机上运行该应用程序。takePicture 功能完美运行。getPicture 函数不起作用。

devTools 控制台显示:

TypeError: Cannot read property 'getPictures' of undefined
    at Object.getPictures (file:///android_asset/www/lib/ngCordova/dist/ng-cordova.js:4420:28)
    at Scope.$scope.getPicture (file:///android_asset/www/js/controllers.js:132:37)

    at tapClick (file:///android_asset/www/lib/ionic/js/ionic.bundle.js:2937:3) 

错误似乎是说 getPictures 在 Scope.$scope.getPicture 的范围内，但这不是代码的组织方式。我已尝试卸载并重新安装 $cordovaImagePicker，但没有任何变化。

经过几个小时的搜索，我找到了这个链接

https://github.com/ratkop/-cordova-imagePickerEx/issues/8

并用这个重新安装 imagePicker:

ionic 插件添加https://github.com/b-alidra/-cordova-imagePickerEx.git --保存

现在它可以正常工作了。
