Doing this in setup will make sure it happens for each test method. 25 | [[[XCUIApplication alloc] init] launch]; 26 | 27 | // In UI tests it’s important to set the initial state - such as interface orientation - required for your tests before they run. The setUp method is a good place to do this. 28 | } 29 | 30 | - (void)tearDown { 31 | // Put teardown code here. This method is called after the invocation of each test method in the class. 32 | [super tearDown]; 33 | } 34 | 35 | - (void)testExample { 36 | // Use recording to get started writing UI tests. 37 | // Use XCTAssert and related functions to verify your tests produce the correct results. 38 | } 39 | 40 | @end 41 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | # MVVMDemo 2 | # 我对iOS开发中使用MVVM的理解(初级) 3 | ![运行](https://github.com/RabbitBell/MVVMDemo/raw/master/运行.PNG) 4 | ## 前言 5 | 之前几个月一直在学习react-native，它的组件化开发真的是很棒，控件和页面的组件化在开发中可以很好的复用，节省开发时间。那个时候还不知道react-native开发用到的就是MVVM设计模式。 6 | 前几天，UI给了新的需求，需要添加几个页面（之前的项目一直使用MVC开发的），在给这几个新页面添加入口的时候，感觉之前写的代码真的是好恶心😱😱😱，就在网上搜了搜MVP和MVVM，发现MVVM和我在写RN时的写法很像。就研究了一下，然后写下了这篇文章。(可能会有很多问题，欢迎评论) 7 | ps：这篇文章实用为主，那些理论性的东西，我都没有研究。 8 | 俗话说得好：黑猫白猫，能用在项目中的就是好🐱 9 | ## 使用 10 | MVVM顾名思义，那就是Model，View，ViewModel，所以我们需要创建这些类了。 11 | 12 | ![项目目录](https://github.com/RabbitBell/MVVMDemo/raw/master/项目目录.png) 13 | 14 | 接下来就把我的理解说说。 15 | ### ViewModelClass 16 | ![ViewModelClass](https://github.com/RabbitBell/MVVMDemo/raw/master/ViewModelClass.png) 17 | `ViewModelClass.h`中 18 | 19 | ``` 20 | #import 21 | #import 22 | 23 | //定义返回请求数据的block类型 24 | typedef void (^ReturnValueBlock) (id returnValue); 25 | typedef void (^ErrorCodeBlock) (id errorCode); 26 | 27 | @interface ViewModelClass : NSObject 28 | 29 | @property (strong, nonatomic) ReturnValueBlock returnBlock; 30 | @property (strong, nonatomic) ErrorCodeBlock errorBlock; 31 | 32 | // 传入交互的Block块 33 | -(void) setBlockWithReturnBlock: (ReturnValueBlock) returnBlock 34 | WithErrorBlock: (ErrorCodeBlock) errorBlock; 35 | @end 36 | ``` 37 | `ViewModelClass.m` 38 | 39 | ``` 40 | #import "ViewModelClass.h" 41 | #import "RTNetworking.h" 42 | 43 | @implementation ViewModelClass 44 | 45 | #pragma 接收传过来的block 46 | -(void) setBlockWithReturnBlock: (ReturnValueBlock) returnBlock 47 | WithErrorBlock: (ErrorCodeBlock) errorBlock 48 | { 49 | _returnBlock = returnBlock; 50 | _errorBlock = errorBlock; 51 | } 52 | @end 53 | ``` 54 | 上面的两个类放着的就是ViewModel的基类，用下面的方法承接之后继承于这个基类的VM中的回调数据。 55 | 56 | ``` 57 | - (void)setBlockWithReturnBlock: (ReturnValueBlock) returnBlock 58 | WithErrorBlock: (ErrorCodeBlock) errorBlock; 59 | ``` 60 | ### ViewController 61 | 我之前的项目用的MVC设计模式，C指的就是这个ViewController了，之前写的垃圾代码，一个Controller里面最多放过1000多行代码，现在去找个方法需要N久。但虽然这是个简单的例子，但其实并不简单。 62 | `ViewController.m` 63 | 64 | 65 | ``` 66 | // 初始化HeaderVM 67 | HeaderVM *headerView = [[HeaderVM alloc] init]; 68 | // 初始化HomeVM 69 | HomeVM *model = [[HomeVM alloc]init]; 70 | // 调用ViewModelClass基类的方法，来获取数据 71 | [model setBlockWithReturnBlock:^(id returnValue) { 72 | 73 | _dataArray = returnValue; 74 | _listArray = returnValue[@"picList"]; 75 | _categoryArray = returnValue[@"category_new"]; 76 | 77 | UIView *view = [headerView headerViewWithData:_categoryArray]; 78 | self.tableView.tableHeaderView = view; 79 | 80 | [self.tableView reloadData]; 81 | 82 | } WithErrorBlock:^(id errorCode) { 83 | 84 | NSLog(@"%@",errorCode); 85 | 86 | }]; 87 | 88 | ``` 89 | 上面的代码虽短，但最重要的东西都在里面，通过Block回调，将需要的数据在VM页面回传了回来。具体内容可以在Demo 90 | 91 | ### HomeVM 92 | ![HomeVM](https://github.com/RabbitBell/MVVMDemo/raw/master/HomeVM.png) 93 | `HomeVM.h` 94 | 95 | ``` 96 | #import "ViewModelClass.h" 97 | 98 | @interface HomeVM : ViewModelClass 99 | 100 | // 获取商品列表 101 | - (void)fetchShopList; 102 | // 跳转到商品详情页 103 | - (void)shopListDetailWithVC:(UIViewController *)vc didSelectRowAtDic:(NSDictionary *)dic; 104 | 105 | @end 106 | ``` 107 | `HomeVM.m` 108 | 109 | ``` 110 | #import "HomeVM.h" 111 | #import "RTNetworking.h" 112 | #import "DetailViewController.h" 113 | 114 | @implementation HomeVM 115 | 116 | - (void)fetchShopList{ 117 | [RTNetworking getWithUrl:@"/v1/Home/all.json" refreshCache:NO success:^(id response) { 118 | [self loadDataWithSuccessDic:response]; 119 | } fail:^(NSError *error) { 120 | self.errorBlock(error); 121 | }]; 122 | } 123 | - (void)loadDataWithSuccessDic:(NSDictionary *)dic{ 124 | NSMutableArray *arr = dic[@"data"]; 125 | self.returnBlock(arr); 126 | } 127 | - (void)shopListDetailWithVC:(UIViewController *)vc didSelectRowAtDic:(NSDictionary *)dic{ 128 | DetailViewController *view = [[DetailViewController alloc]init]; 129 | view.labelText = dic[@"title"]; 130 | [vc.navigationController pushViewController:view animated:YES]; 131 | } 132 | @end 133 | ``` 134 | 135 | 可以明显看出`HomeVM`是继承于`ViewModelClass`，在这个VM中，将Push到新页面的方法也写在了里面。 136 | 137 | ### HeaderVM 138 | 这个是一个tableView的headerView。 139 | ![HeaderV](https://github.com/RabbitBell/MVVMDemo/raw/master/HeaderView.png) 140 | 141 | `HeaderView.h` 142 | 143 | 144 | ``` 145 | #import 146 | #import 147 | #import "ViewModelClass.h" 148 | 149 | @interface HeaderView : ViewModelClass 150 | 151 | // headerView中的数据 152 | - (UIView *)headerViewWithData:(id)data; 153 | 154 | // headerView中的按钮的点击事件 155 | - (void)headerViewDidSeletced:(UIViewController *)vc indexPath:(NSString *)string; 156 | 157 | @end 158 | ``` 159 | `HeaderView.m` 160 | 161 | ``` 162 | #import "HeaderView.h" 163 | #import "UIKit+AFNetworking.h" 164 | #import "DetailViewController.h" 165 | 166 | #define SCREEN_WIDTH [UIScreen mainScreen].bounds.size.width 167 | 168 | @implementation HeaderView{ 169 | UIImageView *topImage; 170 | NSMutableArray *dataArray; 171 | UIButton *button; 172 | } 173 | 174 | - (UIView *)headerViewWithData:(id)data{ 175 | dataArray = data; 176 | UIView * view=[[UIView alloc]initWithFrame:CGRectMake(0, 0,SCREEN_WIDTH,SCREEN_WIDTH/5*2)]; 177 | view.userInteractionEnabled = YES; 178 | 179 | CGFloat btnWidth = SCREEN_WIDTH/5; 180 | CGFloat btnHeight = SCREEN_WIDTH/5; 181 | CGFloat margin=(SCREEN_WIDTH-5*btnWidth)/6; 182 | 183 | for (int i = 0; i
