Ionic开发中常见问题和解决方案记录

1npm按装包失败

更换源：npm config set registry https://registry.npm.taobao.org

或者使用cnpm

sudo npm install -g cnpm --registry=https://registry.npm.taobao.org

2.ionic真机调试

ionic run android --livereload -c -s

3.ionic run ios 报错

sudo npm install -g ios-deploy --unsafe-perm=true

4.跨域(这个问题在android上有，请求发不出去)

cordova plugin add cordova-plugin-whitelist

5.google跨域插件：

Access-Control-Allow-Origin

6.更改statusbar颜色

cordova plugin add cordova-plugin-statusbar

7.ionic生成图标资源

准备好icon.png 和splash.png

ionic resources

8.解决android tabs的布局调到底部，和iOS一致

$ionicConfigProvider.tabs.position('bottom');

9.android录制屏幕：

adb shell screenrecord /sdcard/video/littleQ.mp4 命令录制

问题:

Using this version of Cordova with older version of cordova-android is being deprecated. Consider upgrading to cordova-android@5.0.0 ro newer

删除platforms对应的平台，重新platform add [platform]

ionic build android : Unable to start the daemon process error

在用户文件夹中找到.gradle文件夹，新增gradle.properties文件，内容如下：

org.gradle.jvmargs=-Xmx512m 

ionic跨域问题，在接口端加上：

 response.setHeader("Access-Control-Allow-Origin", "*");  
 response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");    

 

问题：ion-scroll 在 ion-content 里不能上下滑动 的解决方案：

        $timeout(function () {
            //return false; // <--- comment this to "fix" the problem
            var sv = $ionicScrollDelegate.$getByHandle('horizontalScroll').getScrollView();

            var container = sv.__container;

            var originaltouchStart = sv.touchStart;
            var originalmouseDown = sv.mouseDown;
            var originaltouchMove = sv.touchMove;
            var originalmouseMove = sv.mouseMove;

            container.removeEventListener('touchstart', sv.touchStart);
            container.removeEventListener('mousedown', sv.mouseDown);
            document.removeEventListener('touchmove', sv.touchMove);
            document.removeEventListener('mousemove', sv.mousemove);

            sv.touchStart = function (e) {
                e.preventDefault = function () { }
                if (originalmouseMove) {
                    originaltouchStart.apply(sv, [e]);
                }
            }

            sv.touchMove = function (e) {
                e.preventDefault = function () { }
                if (originalmouseMove) {
                    originaltouchMove.apply(sv, [e]);
                }
            }

            sv.mouseDown = function (e) {
                e.preventDefault = function () { }
                if (originalmouseMove) {
                    originalmouseDown.apply(sv, [e]);
                }
            }

            sv.mouseMove = function (e) {
                e.preventDefault = function () { }
                if (originalmouseMove) {
                    originalmouseMove.apply(sv, [e]);
                }
            }

            container.addEventListener("touchstart", sv.touchStart, false);
            container.addEventListener("mousedown", sv.mouseDown, false);
            document.addEventListener("touchmove", sv.touchMove, false);
            document.addEventListener("mousemove", sv.mouseMove, false);
        });
