Ionic 框架介绍  
  
　　Ionic是一个基于Angularjs、可以使用HTML5构建混合移动应用的用户界面框架，它自称为是“本地与HTML5的结合”。该框架提供了很多基本的移动用户界面范例，例如像列表（lists）、标签页栏（tab bars）和触发开关（toggle switches）这样的简单条目。它还提供了更加复杂的可视化布局示例，例如在下面显示内容的滑出式菜单。  
Ionic 自动升级APP  
  
一、准备工作  
  
　　1.Cordova插件：  
  
　　　　cordova plugin add https://github.com/whiteoctober/cordova-plugin-app-version.git  // 获取APP版本  
　　　　cordova plugin add org.apache.cordova.file // 文件系统  
　　　　cordova plugin add org.apache.cordova.file-transfer //文件传输系统  
　　　　cordova plugin add https://github.com/pwlin/cordova-plugin-file-opener2 //文件打开系统  
  
　　2.AngularJS Cordova插件  
  
　　　　ngCordova  
  
二、相关代码，app.js  
复制代码  
  
.run(\['$ionicPlatform', '$rootScope','$ionicActionSheet', '$timeout','$cordovaAppVersion', '$ionicPopup', '$ionicLoading','$cordovaFileTransfer', '$cordovaFile', '$cordovaFileOpener2', function ($ionicPlatform, $rootScope,$ionicActionSheet, $timeout,  $cordovaAppVersion, $ionicPopup, $ionicLoading, $cordovaFileTransfer, $cordovaFile, $cordovaFileOpener2) \{  
        $ionicPlatform.ready(function ($rootScope) \{  
            // Hide the accessory bar by default (remove this to show the accessory bar above the keyboard  
            // for form inputs)  
            if (window.cordova && window.cordova.plugins.Keyboard) \{  
                cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);  
            \}  
            if (window.StatusBar) \{  
                // org.apache.cordova.statusbar required  
                StatusBar.styleDefault();  
            \}  
  
            //检测更新  
            checkUpdate();  
  
            document.addEventListener("menubutton", onHardwareMenuKeyDown, false);  
        \});  
  
  
        // 菜单键  
        function onHardwareMenuKeyDown() \{  
            $ionicActionSheet.show(\{  
                titleText: '检查更新',  
                buttons: \[  
                    \{ text: '关于' \}  
                \],  
                destructiveText: '检查更新',  
                cancelText: '取消',  
                cancel: function () \{  
                    // add cancel code..  
                \},  
                destructiveButtonClicked: function () \{  
                    //检查更新  
                    checkUpdate();  
                \},  
                buttonClicked: function (index) \{  
  
                \}  
            \});  
            $timeout(function () \{  
                hideSheet();  
            \}, 2000);  
        \};  
  
        // 检查更新  
        function checkUpdate() \{  
            var serverAppVersion = "1.0.0"; //从服务端获取最新版本  
            //获取版本  
            $cordovaAppVersion.getAppVersion().then(function (version) \{  
                //如果本地与服务端的APP版本不符合  
                if (version != serverAppVersion) \{  
                    showUpdateConfirm();  
                \}  
            \});  
        \}  
  
        // 显示是否更新对话框  
        function showUpdateConfirm() \{  
            var confirmPopup = $ionicPopup.confirm(\{  
                title: '版本升级',  
                template: '1.xxxx;</br>2.xxxxxx;</br>3.xxxxxx;</br>4.xxxxxx', //从服务端获取更新的内容  
                cancelText: '取消',  
                okText: '升级'  
            \});  
            confirmPopup.then(function (res) \{  
                if (res) \{  
                    $ionicLoading.show(\{  
                        template: "已经下载：0%"  
                    \});  
                    var url = "http://192.168.1.50/1.apk"; //可以从服务端获取更新APP的路径  
                    var targetPath = "file:///storage/sdcard0/Download/1.apk"; //APP下载存放的路径，可以使用cordova file插件进行相关配置  
                    var trustHosts = true  
                    var options = \{\};  
                    $cordovaFileTransfer.download(url, targetPath, options, trustHosts).then(function (result) \{  
                        // 打开下载下来的APP  
                        $cordovaFileOpener2.open(targetPath, 'application/vnd.android.package-archive'  
                        ).then(function () \{  
                                // 成功  
                            \}, function (err) \{  
                                // 错误  
                            \});  
                        $ionicLoading.hide();  
                    \}, function (err) \{  
                        alert('下载失败');  
                    \}, function (progress) \{  
                        //进度，这里使用文字显示下载百分比  
                        $timeout(function () \{  
                            var downloadProgress = (progress.loaded / progress.total) \* 100;  
                            $ionicLoading.show(\{  
                                template: "已经下载：" + Math.floor(downloadProgress) + "%"  
                            \});  
                            if (downloadProgress > 99) \{  
                                $ionicLoading.hide();  
                            \}  
                        \})  
                    \});  
                \} else \{  
                    // 取消更新  
                \}  
            \});  
        \}  
    \}\])

上面是一个简单实现方式，一些数据都在这里写死了，你可以将一些数据从服务端获取，比如最新版本号，最新版的下载路径，这里提供一个思路。
