iOS组件化学习笔记

看了大神示例工程LCLive（面向协议组件化思路），我来总结几个步骤：

LCMediator 作为一个单独的子工程 ，定义各模块协议。只负责定义方法，不负责实现，模块解耦。

1、创建各个模块的协议  LCChatModuleProtocol.h

/**私信模块协议*/

@protocol LCChatModule <NSObject>

/***/

- (UIViewController *)sessionListViewController;

/**读取未读数*/

- (NSUInteger)unreadCount;

/**跳转到单聊聊天详情*/

- (void)pushUserChatViewControllerWithUserId:(NSString *)userId fromViewController:(UIViewController *)viewController;

2、业务工程LCChat中，定义Module类，遵循协议，控制器的实例化与push跳转动作都写在Module中

#import "LCChatModuleProtocol.h"

@interface LCChatModule : NSObject<LCChatModule>

@end

@implementation LCChatModule

- (UIViewController *)sessionListViewController {

    LCSessionListViewController *vc = [[LCSessionListViewController alloc]init];

    returnvc;

}

- (NSUInteger)unreadCount {

    return3;

}

- (void)pushUserChatViewControllerWithUserId:(NSString *)userId fromViewController:(UIViewController *)viewController {

    LCUserChatViewController *userChatVC = [[LCUserChatViewController alloc]init];

    [viewController.navigationController pushViewController:userChatVC animated:YES];

}

@end

3、LCLaunch 工程中，配置控制器初始化的代码

在appDelegate类中执行

- (BOOL)application:(UIApplication*)applicationdidFinishLaunchingWithOptions:(NSDictionary*)launchOptions {

    // Override point for customization after application launch.

    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

    [LCGetModuleInstance(LCLaunchModule)handleDidFinishLaunchingApplication:applicationoptions:launchOptionswindow:self.window];

    return YES;

}

LCLaunchModule类中封装控制器的创建

- (void)handleDidFinishLaunchingApplication:(UIApplication*)applicationoptions:(NSDictionary*)launchOptionswindow:(UIWindow*)window{

    window.backgroundColor = [UIColor whiteColor];

    NSArray*titles =@[@"消息",@"动态",@"我的"];

    NSArray *imageTags = @[@"message",@"moment",@"me"];

    NSMutableArray*viewControllers = [NSMutableArrayarray];

    for(NSIntegeri =0; i < titles.count; i ++) {

        UIViewController*vc =nil;

        switch(i) {

            case0:{

                vc = [LCGetModuleInstance(LCChatModule)sessionListViewController];

            }

                break;

            case1:{

                vc = [LCGetModuleInstance(LCMomentModule)momentListViewController];

            }

                break;

            case2:{

                vc = [LCGetModuleInstance(LCMeModule)meViewController];

            }

                break;

            default:

                break;

        }

        //        NSLog(@"vc = %@",vc);

        UITabBarItem *tabBarItem = [[UITabBarItem alloc]initWithTitle:titles[i] image:[UIImage imageNamed:[NSString stringWithFormat:@"lc_root_tab_%@_normal",imageTags[i]]] selectedImage:[UIImage imageNamed:[NSString stringWithFormat:@"lc_root_tab_%@_pressed",imageTags[i]]]];

        vc.tabBarItem= tabBarItem;

        UINavigationController *nc = [[UINavigationController alloc]initWithRootViewController:vc];

        //        LCNavigationController *nc = [[LCNavigationController alloc]initWithRootViewController:vc];

        [viewControllersaddObject:nc];

    }

    UITabBarController *tbc = [[UITabBarController alloc]init];

    tbc.viewControllers= viewControllers;

    window.rootViewController= tbc;

    [windowmakeKeyAndVisible];

}
