VSRouter

使用方法

VSRouter ( https://github.com/linwaiwai/vsrouter) 是一个iOS路由器，参考了web设计中Router的设计，其提供了iOS中组件解耦一种方式。模块可以自己设计自己资源链接形式，注入Router中。如TestViewController中有：

其使用场景有： 1、提供了应用内部web页面和应用页面资源的相互调用方法。并且保证每个route是可插拔。 2、提供应用间调用之后event dispatch的处理，每个route handle能够方便的插拔。

• (void)load { VSComponentRoute *route = [[VSComponentRoute alloc] initWithPattern:@"/:controler/:action" handler:^BOOL(VSRoute *route) { TestViewController *testViewController = [[TestViewController alloc] init]; UINavigationController navigation = (UINavigationController)[[AppDelegate sharedInstance].window rootViewController]; // route.params [navigation pushViewController:testViewController animated:YES]; return YES; }]; [[VSRouter sharedInstance] addRoute:route]; }

在该文件被引入项目文件中时候，工程文件具备处理如http://:controller/:action (:controller 和 :action 为变量) 或者 vipshop://:controller/:action 这样链接的能力。如果提供给VSComponentRoute的链接有scheme，如：

VSComponentRoute *route = [[VSComponentRoute alloc] initWithPattern:@"vipshop://:controler/:action" handler:^BOOL(VSRoute *route) { }

则指定该Route仅仅接受有vipshop作为shceme的请求信息。为了方便的处理更加复杂的请求URL，VSRoute提供了正则支持：

• (void)load{ __block VSRegexRoute *route = [[VSRegexRoute alloc] initWithPattern:@"/archive/(\d+)/page/(\d+)" map:@{[NSNumber numberWithInteger:0]:@"package", [NSNumber numberWithInteger:1]: @"page"} handler:^BOOL(VSRoute *route) { RegexViewController *testViewController = [[RegexViewController alloc] init]; UINavigationController navigation = (UINavigationController)[[AppDelegate sharedInstance].window rootViewController]; [navigation pushViewController:testViewController animated:YES]; return YES; }]; [[VSRouter sharedInstance] addRoute:route]; }

map指定了变量被映射到参数的时候使用的key。 Web请求的处理 为了方便的处理各种浏览器的请求。VSRoute提供了拦截http的方法（拦截App内部请求，请参考App请求拦截），如有类WebViewController ，写入：

• (void)load{ __block VSComponentRoute route = [[VSComponentRoute alloc] initWithPattern:@"http://" handler:^BOOL(VSRoute *route) { WebViewController *testViewController = [[WebViewController alloc] init]; UINavigationController navigation = (UINavigationController)[[AppDelegate sharedInstance].window rootViewController]; [navigation pushViewController:testViewController animated:YES]; [testViewController loadURL:route.matched]; return YES; }]; [[VSRouter sharedInstance] addRoute:route]; }

表示该controller将处理所有的所有http的请求。 对老代码改造，如有代码：

• (void)openURLWithURLString:(NSString *)urlString { if (urlString != nil && ![urlString isEqualToString:@""]) { self.urlString = urlString; }

  if (self.urlString != nil && ![self.urlString isEqualToString:@""]) { if ([self.urlString rangeOfString:BRANDPRODUCTS].length) { [[VSOpenURLManager sharedInstance] openURLWithURLString:self.urlString rangeString:BRANDPRODUCTS block:^(NSDictionary *paramDic) { NSString *brandId = [paramDic objectForKey:@"brandId"]; NSString *brandName = [paramDic objectForKey:@"brandName"];

            VSGoodsListViewControllerEx *goodListVC = [[[VSGoodsListViewControllerEx alloc] initWithBrandID:brandId brandIndex:-1] autorelease];
            goodListVC.isRoot = YES;
            goodListVC.title = [brandName stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
            goodListVC.pageEvent.parentPage=@"12";
            goodListVC.parentPageSource=@"12";
            [[VSRouteManager defaultManager] routeTo:[VSRouteTarget targetWithViewController:goodListVC
                                                                                     h
        }];
    } else if ([self.urlString rangeOfString:GOODSDETAIL].length) {
        [[VSOpenURLManager sharedInstance] openURLWithURLString:self.urlString rangeString:GOODSDETAIL block:^(NSDictionary *paramDic) {
            NSString *brandId = [paramDic objectForKey:@"brandId"];
            NSString *goodsId = [paramDic objectForKey:@"goodsId"];
            NSString *goodsType = [paramDic objectForKey:@"goodsType"];
            NSString *goodsTitle = [paramDic objectForKey:@"goodsTitle"];
            AccessPath accessPath = apFromOpenURL;
            if ([goodsType isEqualToString:@"1"]){
                accessPath = apFromCosmeticList;
            } else {
                accessPath = apFromOpenURL;
            }
            //进入商品详情
            VSMerchandiseDetailViewController *merchandiseDetailViewController = [[[VSMerchandiseDetailViewController alloc] initWithMerchandiseId:goodsId brandId:brandId accessPath:accessPath] autorelease];
            merchandiseDetailViewController.title = [goodsTitle stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
            VSPullController *pull=[[[VSPullController alloc] initWithRootViewController:merchandiseDetailViewController] autorelease];
            [[VSRouteManager defaultManager] routeTo:[VSRouteTarget targetWithViewController:pull                                                                         
        }];
    }
  

  } }

可在VSGoodsListViewControllerEx 中写入：

• (void)load{ __block VSComponentRoute route = [[VSComponentRoute alloc] initWithPattern:@"http://" handler:^BOOL(VSRoute *route) { NSDictionary *parameters = route.params; NSString *brandId = [parameters objectForKey:@"brandId"]; NSString *brandName = [parameters objectForKey:@"brandName"]; VSGoodsListViewControllerEx *goodListVC = [[[VSGoodsListViewControllerEx alloc] initWithBrandID:brandId brandIndex:-1] autorelease]; goodListVC.isRoot = YES; goodListVC.title = [brandName stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; goodListVC.pageEvent.parentPage=@"12"; goodListVC.parentPageSource=@"12"; [[VSRouteManager defaultManager] routeTo:[VSRouteTarget targetWithViewController:goodListVC ]]; return YES; }]; [[VSRouter sharedInstance] addRoute:route]; }

除了做消息路由之外，VSRoute提供了自动转换机制，同时提供，修改方法。如：

[VSRouter sharedInstance].mapper = (id)^(VSRoute *route, NSDictionary *params){ id expected = [route.expectedClass modelWithJson:params]; return expected; };

VSRoute提供了简单自带可拆卸的自动转换机制。转换之后可以使用route.object 读取。
