ionic中的弹出框---$ionicPopup，

弹出框有两种参看博客，说一下两种弹出框的应用场景

Ionic中（弹出式窗口）的$ionicModal使用方法

function showConfirm() {
                var confirmPopup = $ionicPopup.confirm({
                    title: '<strong>退出应用?</strong>',
                    template: '你肯定要退出应用吗?',
                    okText: '退出',
                    cancelText: '取消'
                });

                confirmPopup.then(function (res) {
                    if (res) {
                        ionic.Platform.exitApp();
                    } else {
                        // Don't close
                    }
                });
            }
