  • 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];

            break;

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

    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

    switch (result) {
        case 0:
            //连接远程数据库失败
            [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:

            [self showAlertInfoWithTag:2 andMessage:@"注册失败
