• iOS开发实战-时光记账Demo 网络版


    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

    服务器交互.png

    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
      user表
      相反Tally与Users的关系就是:一对多
      tally表

    • 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"
    
    @interface LoginViewController ()<ServerOperationsDelegate>
    @property (weak, nonatomic) IBOutlet UITextField *userNameField;
    @property (weak, nonatomic) IBOutlet UITextField *userPswField;
    
    @end
    
    @implementation LoginViewController
    
    - (void)viewDidLoad {
        [super viewDidLoad];
        self.title = @"登录";
        [[CoreDataOperations sharedInstance] loadTallyTypeToSqlite];
        // Do any additional setup after loading the view.
    }
    
    - (void)viewWillAppear:(BOOL)animated{
        self.userNameField.text = [[NSUserDefaults standardUserDefaults] objectForKey:@"userName"];
        self.userPswField.text = nil;
    }
    
    - (void)didReceiveMemoryWarning {
        [super didReceiveMemoryWarning];
        // Dispose of any resources that can be recreated.
    }
    //去注册
    - (IBAction)clickRegister:(id)sender {
        [self.userPswField resignFirstResponder];
        [self.userPswField resignFirstResponder];
    }
    
    //输入检查 6-20为正常字符
    - (BOOL)inputCheck:(NSString*)passWord{
        NSString *passWordRegex = @"^[a-zA-Z0-9]{6,20}+$";
        NSPredicate *passWordPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",passWordRegex];
        return [passWordPredicate evaluateWithObject:passWord];
        
    }
    
    //去登录
    - (IBAction)clickLogin:(id)sender {
        
        //输入检查
        BOOL userNameCheck = [self inputCheck:self.userNameField.text];
        BOOL userPswCheck = [self inputCheck:self.userPswField.text];
        if (!userNameCheck | !userPswCheck) {
            [self showAlertInfoWithTag:999 andMessage:@"用户名或密码出错
    请输入6-20位合法字符"];
            return;
        }
        //键盘收起
        [self.userPswField resignFirstResponder];
        [self.userNameField resignFirstResponder];
        
        ServerOperations *op = [ServerOperations sharedInstance];
        op.delegate = self;
        [op loginWithUser:self.userNameField.text andPsw:self.userPswField.text];
    }
    
    //登录结果
    - (void)didLoginBackWithTag:(int)tag{
        [self loginAlertWithReslut:tag];
    }
    
    //验证登录
    - (void)loginAlertWithReslut:(int)result{
        switch (result) {
            case 0:
                //连接远程数据库失败
                [self showAlertInfoWithTag:result andMessage:@"连接远程数据库失败"];
                break;
            case 1:
                //验证成功
                [self performSegueWithIdentifier:@"toHome" sender:nil];
                break;
            case 2:
                //密码错误
                [self showAlertInfoWithTag:result andMessage:@"密码错误"];
                break;
            case 3:
                //用户不存在
                [self showAlertInfoWithTag:result andMessage:@"用户名不存在
    请注册"];
                break;
            default:
                break;
        }
    }
    
    //弹出提示框
    - (void)showAlertInfoWithTag:(int)tag andMessage:(NSString*)message {
        UIAlertController *alertVC =[UIAlertController alertControllerWithTitle:@"提示" message:message preferredStyle:UIAlertControllerStyleAlert];
        [alertVC addAction:[UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:nil]];
        if (tag == 3) {
            [alertVC addAction:[UIAlertAction actionWithTitle:@"注册" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
                [self performSegueWithIdentifier:@"toRegister" sender:nil];
            }]];
        }
        [self presentViewController:alertVC animated:YES completion:nil];
    }
    
    -(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
        NSLog(@"准备push");
        //本地保存用户名
        [[NSUserDefaults standardUserDefaults] setBool:NO forKey:@"isLoaded"];
        [[NSUserDefaults standardUserDefaults] setObject:self.userNameField.text forKey:@"userName"];
        
    }
    @end
    

    注册

    注册也很简单,发送注册信息给服务器,服务器判断下用户名是否存在就行。

    #import "RegisterViewController.h"
    
    @interface RegisterViewController ()<ServerOperationsDelegate>
    @property (weak, nonatomic) IBOutlet UITextField *userNameField;

        [super viewDidLoad];
        self.title = @"注册";
    }
    
    - (void)didReceiveMemoryWarning {
        [super didReceiveMemoryWarning];
        // Dispose of any resources that can be recreated.
    }
    
    //输入检查 6-20为正常字符
    - (BOOL)inputCheck:(NSString*)passWord{
        NSString *passWordRegex = @"^[a-zA-Z0-9]{6,20}+$";
        NSPredicate *passWordPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",passWordRegex];
        return [passWordPredicate evaluateWithObject:passWord];
        
    }
    
    - (void)didRegisterBackWithTag:(int)tag{
        [self loginAlertWithReslut:tag];
    }
    
    //提交注册
    - (IBAction)clickRegister:(id)sender {
        
        //输入检查
        BOOL userNameCheck = [self inputCheck:self.userNameField.text];
        BOOL userPswCheck = [self inputCheck:self.userPswField.text];
        if (!userNameCheck | !userPswCheck) {
            [self showAlertInfoWithTag:0 andMessage:@"用户名或密码出错
    请输入6-20位合法字符"];
            return;
        }
        
        //取消键盘响应
        [self.userNameField resignFirstResponder];
        [self.userPswField resignFirstResponder];
    
        ServerOperations *ops = [ServerOperations sharedInstance];
        ops.delegate = self;
        [ops registerWithUser:self.userNameField.text andPsw:self.userPswField.text];
    }
    
    //登录提示
    - (void)loginAlertWithReslut:(int)result{
        switch (result) {

                [self showAlertInfoWithTag:0 andMessage:@"连接远程数据库失败"];
                break;
            case 1:
                //注册成功
                [self showAlertInfoWithTag:1 andMessage:@"注册成功"];
                break;
            case 2:
                //注册失败 用户已经存在
                [self showAlertInfoWithTag:2 andMessage:@"注册失败
    用户已经存在"];
                break;
            default:
                break;
        }
    }
    
    //弹出提示框
    - (void)showAlertInfoWithTag:(int)tag andMessage:(NSString*)message {
        UIAlertController *alertVC =[UIAlertController alertControllerWithTitle:@"提示" message:message preferredStyle:UIAlertControllerStyleAlert];
        if (tag == 1) {
            [alertVC addAction:[UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
                [[NSUserDefaults standardUserDefaults] setObject:self.userNameField.text forKey:@"userName"];
                [self.navigationController popViewControllerAnimated:YES];
            }]];
    
        }else{
            [alertVC addAction:[UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:nil]];
    
        }
        [self presentViewController:alertVC animated:YES completion:nil];
    }
