使用cordova插件删除iOS中应用程序的临时目录

我使用ionic框架在iOS的Library目录中的应用程序中存储一些图像。是否可以使用Cordova插件文件和Cordova插入文件传输删除相同的目录？

有人能帮忙吗？

我下载图像的代码是：

downloadImage: function(url, fileName) {
        var deferred = $q.defer();
        window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function(fs) {
                fs.root.getDirectory(
                    LOCAL_STORAGE_KEYS.app, {
                        create: true
                    },
                    function(dirEntry) {
                        // console.log(arguments);
                        dirEntry.getFile(
                            fileName, {
                                create: true,
                                exclusive: false
                            },
                            function(fe) {
                                console.log(arguments);
                                var p = fe.toURL();
                                console.log("In service the url path:", p);
                                fe.remove();
                                var ft = new FileTransfer();
                                console.log('File Transfer instance:', ft);
                                ft.download(
                                    encodeURI(url),
                                    p,
                                    function(entry) {
                                        console.log('In service the entry callback:', entry);
                                        if (entry && entry.toURL) {
                                            deferred.resolve(entry.toURL());
                                        } else {
                                            console.log('No entry:', arguments);
                                            deferred.resolve();
                                        }
                                    },
                                    function(err) {
                                        console.log('Getting rejected:', err);
                                        deferred.reject(err);
                                    },
                                    false,
                                    null
                                );
                            },
                            function() {
                                deferred.reject(new Error('get file  failed'));
                            }
                        );
                    }
                );
            },
            function() {
                deferred.reject(new Error('get directory failed'));
            });
        return deferred.promise;
    }
