之前写了一个本地数据库版本 戳这里
现在这个就是增加了后台 登录注册页面以及web的上传记录展示页面
含有少量php有兴趣可以看下
另外demo中包括数据库操作、json、网络请求等都没有用到第三方库,所以网络方面的逻辑可能有所欠缺,大神请轻拍。
效果
分析
很简单的分析把大致需要编写的模块列出
客户端部分
分析
- 与本地版的demo相比主要是多了服务器请求操作
新增数据库内容:
-
Users表
与Tally表关系:一对多
相反Tally与Users的关系就是:一对多
-
flag字段 决定是否上传
-
需要发送请求的位置
- 登录
- 注册
- 登录成功后第一次加载
- 新增账单
- 修改账单
- 删除账单
代码
登录
登录时向服务器发送用户名和密码,当然只有两个结果:未注册 和 密码错误
#import "LoginViewController.h"

@property (weak, nonatomic) IBOutlet UITextField *userPswField;
