1、MVC

Apple官方最標(biāo)準(zhǔn)的是UITableViewController

// VC里面對(duì)view進(jìn)行賦值。
cell.textLabel.text = model.title;
delegate

2、MVC變種

view.model = model;
view.delegate = self;

3、MVP

VC任命一個(gè)presenter幫他處理相關(guān)業(yè)務(wù)，實(shí)現(xiàn)代碼拆分。相當(dāng)于manager

// VC中
self.presenter = [[MJAppPresenter alloc] initWithController:self];
// presenter里面處理view、model、delegate
- (instancetype)initWithController:(UIViewController *)controller
{
    if (self = [super init]) {
        self.controller = controller;
        
        // 創(chuàng)建View
        MJAppView *appView = [[MJAppView alloc] initWithFrame:CGRectMake(100, 100, 100, 150)];
        appView.delegate = self;
        [controller.view addSubview:appView];
        
        // 加載模型數(shù)據(jù)
        MJApp *app = [[MJApp alloc] init];
        app.name = @"QQ";
        app.image = @"QQ";
        
        // 賦值數(shù)據(jù)
        [appView setName:app.name andImage:app.image];
//        appView.iconView.image = [UIImage imageNamed:app.image];
//        appView.nameLabel.text = app.name;
    }
    return self;
}

#pragma mark - MJAppViewDelegate
- (void)appViewDidClick:(MJAppView *)appView
{
    NSLog(@"presenter 監(jiān)聽(tīng)了 appView 的點(diǎn)擊");
}

3、MVVM

相當(dāng)于MVP中的P換成了VM，然后加了監(jiān)聽(tīng)機(jī)制(RAC或KVO)

// ViewModel
- (instancetype)initWithController:(UIViewController *)controller
{
    if (self = [super init]) {
        self.controller = controller;
        
        // 創(chuàng)建View
        MJAppView *appView = [[MJAppView alloc] init];
        appView.frame = CGRectMake(100, 100, 100, 150);
        appView.delegate = self;
        appView.viewModel = self;
        [controller.view addSubview:appView];
        
        // 加載模型數(shù)據(jù)
        MJApp *app = [[MJApp alloc] init];
        app.name = @"QQ";
        app.image = @"QQ";
        
        // 設(shè)置數(shù)據(jù)
        self.name = app.name;
        self.image = app.image;
    }
    return self;
}
// View
- (void)setViewModel:(MJAppViewModel *)viewModel
{
    _viewModel = viewModel;
    
    __weak typeof(self) waekSelf = self;
    [self.KVOController observe:viewModel keyPath:@"name" options:NSKeyValueObservingOptionNew block:^(id  _Nullable observer, id  _Nonnull object, NSDictionary<NSKeyValueChangeKey,id> * _Nonnull change) {
        waekSelf.nameLabel.text = change[NSKeyValueChangeNewKey];
    }];
    
    [self.KVOController observe:viewModel keyPath:@"image" options:NSKeyValueObservingOptionNew block:^(id  _Nullable observer, id  _Nonnull object, NSDictionary<NSKeyValueChangeKey,id> * _Nonnull change) {
        waekSelf.iconView.image = [UIImage imageNamed:change[NSKeyValueChangeNewKey]];
    }];
}

4、分層

界面層- 新聞列表，tableview
業(yè)務(wù)層- 加載展示數(shù)據(jù)，一些業(yè)務(wù)邏輯
數(shù)據(jù)層- 網(wǎng)絡(luò)或本地

5、設(shè)計(jì)模式

比架構(gòu)小，關(guān)注類(lèi)與類(lèi)之間的關(guān)系，主要有六大原則：依賴(lài)倒置、單一職責(zé)、最小知道、開(kāi)閉、里氏替換、迪米特(鄰近)

6、組件化
