Upgrading Cordova-iOS apps Outside App Store

· Java Zone

Microservices! They are everywhere, or at least, the term is. When should you use a microservice architecture? What factors should be considered when making that decision? Do the benefits outweigh the costs? Why is everyone so excited about them, anyway?  Brought to you in partnership with IBM.

In one of my last post I explained how to upgrade Cordova-Android apps outside Google Play Store with angularjs. Today is the turn of iOS applications.

If you work with in-house iOS applications you need to define a distribution strategy (you cannot use Apple Store, indeed). Apple provides documentation to do it. Basically we need to place our ipa file in addition to the plist file (generated when we archive our application with xCode). I’m not going to explain how to do it here. As I said before it’s well documented. Here I’m going to explain how to do the same trick than the Android’s post but now with our iOS application.

With iOS, to install the application, we only need to provide the iTunes link to our plist application (something like this: itms-services://?action=download-manifest&url=http://url.to.plist) and open it with the InAppBrowser plugin.

First we install the InAppBrowser plugin:

$ cordova plugin add https://git-wip-us.apache.org/repos/asf/cordova-plugin-inappbrowser.git

And now we only need to open the url using the plugin:

var iosPlistUrl = 'http://url.to.plist';
cordova.exec(null, null, "InAppBrowser", "open", [encodeURI("itms-services://?action=download-manifest&url=" + iosPlistUrl), "_system"]);

We can use exactly the same angularJs used the the previous post to check the version and the same server-side verification.

We also can detect the platform with Device plugin and do one thing or another depending on we are using Android or iOS.

Here you can see one example using ionic framework. This example uses one $http interceptor to send version number within each request and we trigger ‘wrong.version’ to the event dispatcher when it detects a wrong versions between client and server

angular.module('G', ['ionic'])
 
    .value('appConf', {
        version: 1,
        apiHost: 'http://localhost:8080'
    })
 
    .config(function ($httpProvider, $urlRouterProvider, $stateProvider) {
        $httpProvider.interceptors.push('versionInterceptor');
 
        $stateProvider
            .state('home', {
                url: '/home',
                templateUrl: 'partials/home.html',
                controller: 'HomeController'
            })
            .state('upgrade', {
                url: '/upgrade',
                templateUrl: 'partials/upgrade.html',
                controller: 'UpgradeController'
            })
        ;
 
        $urlRouterProvider.otherwise('/home');
 
    })
 
    .run(function ($ionicPlatform, $rootScope, $state) {
        $ionicPlatform.ready(function () {
            if (window.cordova && window.cordova.plugins.Keyboard) {
                cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
            }
            if (window.StatusBar) {
                StatusBar.styleDefault();
            }
        });
 
        $rootScope.$on('wrong.version', function () {
            $state.go("upgrade");
        });
    })
 
    .controller('HomeController', function ($scope, $http, appConf) {
        $scope.someAction = function () {
            $http.get(appConf.apiHost + "/hello", function (data) {
                alert(data);
            });
        }
    })
 
    .controller('UpgradeController', function ($scope) {
        $scope.upgrade = function () {
            cordova.exec(null, null, "InAppBrowser", "open", [encodeURI("itms-services://?action=download-manifest&url=https://path/to/plist.plist"), "_system"]);
        }
    })
 
    .factory('versionInterceptor', function ($rootScope, appConf) {
        var versionInterceptor = {
            request: function (config) {
                config.url = config.url + '?_version=' + appConf.version;
 
                return config;
            },
            responseError: function(response) {
                if (response.status == 410) {
                    $rootScope.$emit('wrong.version');
                }
            }
        };
 
        return versionInterceptor;
    })
;
