搭建app框架-MVVM+RAC+路由
项目的介绍
项目使用了ReactiveCocoa框架，实现了MVVM架构，使用MVVM架构主要目的是分离视图(View)和模型(Model)。
MVVM四大优点:
- 低耦合。视图（View）可以独立于Model变化和修改，一个ViewModel可以绑定到不同的"View"上，当View变化的时候Model可以不变，当Model变化的时候View也可以不变。
- 可重用性。你可以把一些视图逻辑放在一个ViewModel里面，让很多view重用这段视图逻辑。
- 独立开发。开发人员可以专注于业务逻辑和数据的开发（ViewModel），设计人员可以专注于页面设计，使用Expression Blend可以很容易设计界面并生成xaml代码。
- 可测试。界面素来是比较难于测试的，而现在测试可以针对ViewModel来写
项目的搭建
- 1.搭建项目主框架

-
2.CocoaPods集成的第三方框架
- AFNetworking 网络请求
- DateTools 日期的相对处理
- JLRoutes 路由跳转
- JPFPSStatus 显示屏幕的帧数
- MBProgressHUD 蒙版
- MJExtension 字典转模型框架
- MJRefresh 界面刷新
- MYLayout 浮动布局
- ReactiveCocoa 函数响应式编程
- SDAutoLayout 简单的布局
- SDCycleScrollVIew 无限循环轮播图
- SDWebImage 加载图片
3.初步搭建界面
1.初始化项目
- (void)registerRoutes{
WZXTabBarController *rootVC = [WZXTabBarController tabBarControllerWithAddChildVCsBlock:^(WZXTabBarController *tabBarC) {
[tabBarC addChildVC:[WZXHomeViewController new] title:@"主页" normalImageName:@"tabar_zhuye2.png" selectedImageName:@"tabar_zhuye.png" isRequiredNavController:YES];
[tabBarC addChildVC:[WZXCircleFriendsViewController new] title:@"主页2" normalImageName:@"tabar_tuijian2.png" selectedImageName:@"tabar_tuijiani.png" isRequiredNavController:YES];
[tabBarC addChildVC:[WZXHomeViewController new] title:@"中间按钮" normalImageName:@"tabar_suishoupai2.png" selectedImageName:@"tabar_suishoupai.png" isRequiredNavController:YES];
[tabBarC addChildVC:[WZXFindViewController new] title:@"朋友" normalImageName:@"tabar_linxin2.png" selectedImageName:@"tabar_linxin.png" isRequiredNavController:YES];
[tabBarC addChildVC:[WZXAccountViewController new] title:@"我的" normalImageName:@"tabar_geren2.png" selectedImageName:@"tabar_geren.png" isRequiredNavController:YES];
}];
self.window = [[UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds];
self.window.backgroundColor = [UIColor whiteColor];
self.window.rootViewController = rootVC;
[self.window makeKeyAndVisible];
// navigation Push规则
[[JLRoutes globalRoutes] addRoute:@"/NaviPush/:controller" handler:^BOOL(NSDictionary<NSString *,NSString *> * _Nonnull parameters) {
NSLog(@"parameters==%@",parameters);
UIViewController *v = [[NSClassFromString(parameters[@"controller"]) alloc] init];
[self paramToVc:v param:parameters];
[[self currentViewController] pushViewController:v animated:YES];
return YES;
}];
}
- 2.路由跳转
-(void)paramToVc:(UIViewController *) v param:(NSDictionary<NSString *,NSString *> *)parameters{
// runtime将参数传递至需要跳转的控制器
unsigned int outCount = 0;
objc_property_t * properties = class_copyPropertyList(v.class , &outCount);
for (int i = 0; i < outCount; i++) {
objc_property_t property = properties[i];
NSString *key = [NSString stringWithUTF8String:property_getName(property)];
NSString *param = parameters[key];
if (param != nil) {
[v setValue:param forKey:key];
}
}
}
/**
* 获取当前控制器
*/
-(UINavigationController *)currentViewController{
WZXTabBarController *WZXTabBar = (WZXTabBarController *)self.window.rootViewController;
return WZXTabBar.selectedViewController;
}
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options {
NSLog(@"从哪个app跳转而来 Bundle ID: %@", options[UIApplicationOpenURLOptionsSourceApplicationKey]);
NSLog(@"URL scheme:%@", [url scheme]);
#pragma mark - JLRoutes（默认的Scheme）
return [[JLRoutes globalRoutes] routeURL:url];
}
- (void)urlClick{
// 发送请求
RACSignal *signal = [[[WZXHomeViewModel alloc]init].requestCommand execute:@{@"code":@"Home"}];
[signal subscribeNext:^(id x) {
NSLog(@"%@",x);
NSString *customURL = @"WZXArchitecture://NaviPush/TwoViewController?name=home&userId=99999&age=18&adbc=29";
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:customURL]];
}];
}
3.自定义Category
WZXNetworking 网络请求框架
UIView+Extension 控件frame的拓展
MBProgressHUD+WZX HUD网络提示
UIImage+WZXGImage 绘制圆角图片
NSString+WZXString 字符串的加密和验证等
NSArray+WZX 防止数组Crash
NSDictionary+WZX 防止字典的部分操作Crash
UIColor+WZX 颜色十六进制转换UIColor
