页面跳转
MBProgressHUD第三方类库
数据存储
UITableView深入理解
代理（代理传值）

storyBoard实现页面跳转布局

删除系统的VC storyBoard中的xib 拖拽自己的xib并添加导航控制器 item等等最后创建VC进行关联

实现输入框的监听

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    
    [self addobser];
}

- (void)addobser{
    // 注册通知 添加观察者
    /*
     observer:给self添加 的意思是针对本控制器
     selector:调用的方法
     name:表示对哪一个属性观察
     object:表示要观察的对象
     */
    //    添加用户名输入框观察者
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(textChange) name:UITextFieldTextDidChangeNotification object:self.nameField];
    //    添加密码输入框观察者
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(textChange) name:UITextFieldTextDidChangeNotification object:self.passwordField];
}```

pragma mark - 文本框变化后调用的方法

(void)textChange{
// if (self.nameField.text.length && self.passwordField.text.length) {
// self.loginBtn.enabled = YES;
// }else{
// self.loginBtn.enabled = NO;
// }
// 等价于三目运算符
self.loginBtn.enabled = (self.nameField.text.length && self.passwordField.text.length);
}
(void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}```

效果：

实现Segue的传值和跳转

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; color: #78492a}p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; color: #008400}p.p3 {margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo}p.p4 {margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; color: #703daa}p.p5 {margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; min-height: 21.0px}p.p6 {margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; color: #3d1d81}span.s1 {font-variant-ligatures: no-common-ligatures}span.s2 {font: 18.0px 'Heiti SC Light'; font-variant-ligatures: no-common-ligatures}span.s3 {font-variant-ligatures: no-common-ligatures; color: #bb2ca2}span.s4 {font-variant-ligatures: no-common-ligatures; color: #703daa}span.s5 {font-variant-ligatures: no-common-ligatures; color: #000000}span.s6 {font-variant-ligatures: no-common-ligatures; color: #3d1d81}span.s7 {font-variant-ligatures: no-common-ligatures; color: #d12f1b}span.s8 {font: 18.0px 'Heiti SC Light'; font-variant-ligatures: no-common-ligatures; color: #d12f1b}span.s9 {font-variant-ligatures: no-common-ligatures; color: #4f8187}

#pragma mark - Navigation 跳转之前的准备工作
// In a storyboard-based application, you will often want to do a little preparation before navigation
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    // Get the new view controller using [segue destinationViewController].
    // Pass the selected object to the new view controller.
    //1:取得目标控制器
    UIViewController *contactVC = segue.destinationViewController;
    // 2:设置标题（传值）
    contactVC.title = [NSString stringWithFormat:@"%@的联系人列表",self.nameField.text];
}

#pragma mark - 当用户点击之后 实现传值和跳转工作
- (IBAction)loginOnclick:(id)sender {
    // 执行跳转
    [self performSegueWithIdentifier:@"LoginToContact" sender:nil];
}```

效果

###UIAlertViewController与添加页面布局

(IBAction)exitAction:(id)sender {
UIAlertController *alertC = [UIAlertController alertControllerWithTitle:@"要注销吗" message:@"真的要注销吗？" preferredStyle:UIAlertControllerStyleActionSheet];
// 添加取消按钮
[alertC addAction:[UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:nil]];
// 添加确定按钮
[alertC addAction:[UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDestructive handler:^(UIAlertAction * _Nonnull action) {
[self.navigationController popViewControllerAnimated:NO];
}]];
// 弹出
[self presentViewController:alertC animated:YES completion:nil];

}```

添加功能与传值

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; color: #d12f1b}p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; min-height: 21.0px}p.p3 {margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; color: #4f8187}p.p4 {margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo}p.p5 {margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; color: #bb2ca2}span.s1 {font-variant-ligatures: no-common-ligatures; color: #78492a}span.s2 {font-variant-ligatures: no-common-ligatures}span.s3 {font-variant-ligatures: no-common-ligatures; color: #bb2ca2}span.s4 {font-variant-ligatures: no-common-ligatures; color: #000000}span.s5 {font-variant-ligatures: no-common-ligatures; color: #703daa}span.s6 {font-variant-ligatures: no-common-ligatures; color: #4f8187}

}
(void)textChange{

}

pragma mark - 视图已经出现让输入框成为第一响应者

[self.delegate addContact:self didAddContact:contactModel];
}
}
(void)didReceiveMemoryWarning {

@end```

联系人控制器获取并刷新数据

设置代理遵守代理实现代理方法中获取数据刷新TableView 并存储数据

数据归档存储

用户名密码记住密码用NSUserDefults存储
编写key 存储于读取

// 数据存储
#define User_Name_Key @"name"
#define PWD_key @"password"
#define RemPwdKry @"rem_pwd"```

- 读取数据

(void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.

// 读取上次的配置
NSUserDefaults *defults = [NSUserDefaults standardUserDefaults];
self.nameField.text = [defults valueForKey:User_Name_Key];
self.passwordField.text = [defults valueForKey:PWD_key];
self.remberSwitch.on = [defults boolForKey:RemPwdKry];
// 如果开关打开密码框则自动存入数据
if (self.remberSwitch.isOn) {
self.passwordField.text = [defults valueForKey:PWD_key];
self.loginBtn.enabled = YES;
}

// 监听输入框
[self addobser];
}```
存储数据并同步数据

#pragma mark - 当用户点击之后 实现传值和跳转工作
- (IBAction)loginOnclick:(id)sender {
    if (![self.nameField.text isEqualToString:@"jafar"]) {
        [MBProgressHUD showError:@"账号不存在"];
        return;
    }
    if (![self.passwordField.text isEqualToString:@"jyf2015."]){
        [MBProgressHUD showError:@"密码错误"];
        return;
    }
    // 显示蒙版
    [MBProgressHUD showMessage:@"正在登录"];
    // 模拟两秒时间，结束跳转
    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(2.0 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
        // 移除遮盖
        [MBProgressHUD hideHUD];
        // 执行跳转
        [self performSegueWithIdentifier:@"LoginToContact" sender:nil];
    });
    
    // 存储用户名和密码
    NSUserDefaults *userDefult = [NSUserDefaults standardUserDefaults];
    [userDefult setValue:self.nameField.text forKey:User_Name_Key];
    [userDefult setValue:self.passwordField.text forKey:PWD_key];
    [userDefult setBool:self.remberSwitch.isOn forKey:RemPwdKry];
    [userDefult synchronize];   // 同步
}```

####数据模型的存储方式

- 归档  遵守归档协议 编写路径宏定义 存储  取出  展示  可以存储数组类型哦

import <Foundation/Foundation.h>

@interface ContactModel : NSObject<NSCoding>

@property(nonatomic, copy) NSString * name;
@property(nonatomic, copy) NSString * phone;

@end```

#import "ContactModel.h"

@implementation ContactModel

/*
 将某个对象写入文件是会调用
 在这个方法中说清楚哪些属性需要存储
 */
- (void)encodeWithCoder:(NSCoder *)aCoder{
    [aCoder encodeObject:self.name forKey:@"name"];
    [aCoder encodeObject:self.phone forKey:@"phone"];
}

/*
 解析对象的时候会调用这个方法
 需要解析哪些属性
 */

- (instancetype)initWithCoder:(NSCoder *)aDecoder{
    if (self = [super init]) {
        self.name = [aDecoder decodeObjectForKey:@"name"];
        self.phone = [aDecoder decodeObjectForKey:@"phone"];
    }
    return self;
}
@end```

//路径

define ContactFilePath [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject] stringByAppendingPathComponent:@"contacts.data"]```

数组获取的时候先从本地来获取

@interface ContactTableViewController ()<AddVCDelegate,EditTVCDelegate>

@property (nonatomic, strong) NSMutableArray *contactArr;   // 联系人数组

@end

@implementation ContactTableViewController

#pragma mark - 懒加载
- (NSMutableArray *)contactArr{
    if (!_contactArr) {
        // 数据解码
        _contactArr = [NSKeyedUnarchiver unarchiveObjectWithFile:ContactFilePath];
        if (_contactArr == nil) {
            _contactArr = [NSMutableArray array];
        }
    }
    return _contactArr;
    
}```

- 存储 这里注意 不管是添加联系人还是编辑修改之后的数据都要重新归档

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; color: #78492a}p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo}p.p3 {margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px 'Heiti SC Light'; color: #008400}p.p4 {margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; color: #008400}p.p5 {margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; color: #3d1d81}p.p6 {margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; min-height: 21.0px}span.s1 {font-variant-ligatures: no-common-ligatures}span.s2 {font-variant-ligatures: no-common-ligatures; color: #bb2ca2}span.s3 {font-variant-ligatures: no-common-ligatures; color: #4f8187}span.s4 {font: 18.0px Menlo; font-variant-ligatures: no-common-ligatures; color: #000000}span.s5 {font: 18.0px Menlo; font-variant-ligatures: no-common-ligatures}span.s6 {font-variant-ligatures: no-common-ligatures; color: #3d1d81}span.s7 {font-variant-ligatures: no-common-ligatures; color: #000000}span.s8 {font: 18.0px 'Heiti SC Light'; font-variant-ligatures: no-common-ligatures}span.s9 {font-variant-ligatures: no-common-ligatures; color: #703daa}span.s10 {font-variant-ligatures: no-common-ligatures; color: #78492a}
