学习技术的最好方式就是做项目,边做功能边看文档,我需要这个推送那我就去看推送文档.就是这样.不是先学再去做,做中学习效率快,成就感,还到赚钱,快乐. 没项目就去看书籍,很枯燥,反正做中看文档的学习方式适合我.

FMDN离线复杂数据存储
拍照给相机显示水印
极光推送
加载html本地显示
上传照片到阿里百川

目录结构

已经App Store上架,这是一款企业级的应用.需要企业账户可以登录.前期2人搭建基础,后期个人单独完成1.0到2.0的版本升级.

首页界面

通用类

结构

App Store上架

1.根据网上资料配置各种证书,耐心加细心.

FMDN离线复杂数据存储

数据结构如下:模型里套模型,模型里有字典,字典里有字典的结果需要离线传递到下个控制器.
参考FMDB安装使用帮助如何引入fmdb到自己xcode项目里.

实现原理:
在启动页面创建数据库,如果没有就创建一张表.用到了:数据库操作.
数据库语言sql操作学习链接.

拍照给相机显示水印

正在拍摄的界面

拍摄完预览的图片

实现原理 使用第三方的相机框架(ZHGWaterMarkMeetingCameraVC.h).可以自定义水印.

极光推送

场景:
1.上传操作服务器推送到手机
2.后台推送到手机

加载html本地显示

提交审核下面是html网页

实现原理:
1.下载html.zip到本地
2.解压
3.根据本地路径去取响应子文件的html文件
4.webview去加载
代码:

上传照片到阿里百川

总结: 阿里百川不好用,异步操作和循环时会把错误的url也返回给我,很多bug没人修复,客服联系不上,不建议使用.
