基础模块 -> 通用模块 -> 业务模块
只能上层对下层依赖，项⽬公共代码资源 下沉，横向的依赖 最好下沉
组件化需求：
模块间解耦
模块重⽤
提⾼团队协作开发效率
单元测试
不需要组件化：
项⽬较⼩，模块间交互简单，耦合少
模块没有被多个外部模块引⽤，只是⼀个单独的⼩模块
模块不需要重⽤，代码也很少被修改
团队规模很⼩
Cocopods 实现组件化
pod lib create xxx
创建CommonUIModule模块
CommonUIModule -> Assets 图片和资源
CommonUIModule -> Classes 代码
Example CommonUIModule使用案例
Podfile 文件 -> pod install
引用CommonUIModule本身模块，
引用其他模块 MacroAndCategoryModule
use_frameworks!
platform :ios, '9.0'
target 'CommonUIModule_Example' do
pod 'CommonUIModule', :path => '../'
pod 'MacroAndCategoryModule', :path => '../../MacroAndCategoryModule'
...
end
引用Cocopods 线上库
Development Pods -> Pod -> CommonUIModule.podspec
自身模块使用图片
1.打开 resource
2. pathForResource 读取资源
NSString *path = [[NSBundle mainBundle] pathForResource:[NSString stringWithFormat:@"Home_TableView_Response_%@", channelId] ofType:@"json"];
NSData*data = [NSDatadataWithContentsOfFile:path];
主模块读取子模块的 图片和资源
1.打开 resource
2. pathForResource 读取资源
NSString *bundlePath = [[NSBundle bundleForClass:[self class]].resourcePath stringByAppendingPathComponent:@"/LGHomeModule.bundle"];
NSBundle*resoure_bundle = [NSBundlebundleWithPath:bundlePath];
[UIImage imageNamed:@"" inBundle:resoure_bundle withConfiguration:nil];
CTMediator 模块之间解耦
Actions 响应者
Target_A.h 以Target_开头的
Target_A -> DemoModuleADetailViewController
中间层CTMediator
本地组件调用入口
- (id_Nullable)performTarget:(NSString *_Nullable)targetName action:(NSString *_Nullable)actionName params:(NSDictionary*_Nullable)params
targetClassString = [NSStringstringWithFormat:@"Target_%@", targetName];
Class targetClass = NSClassFromString(targetClassString);
target = [[targetClass alloc] init];
NSString*actionString = [NSString stringWithFormat:@"Action_%@:", actionName];
SEL action =NSSelectorFromString(actionString);
[self safePerformAction:action target:target params:params]
方法执行： 快速转发 或 performSelector
- (id)safePerformAction:(SEL)actiontarget:(NSObject*)targetparams:(NSDictionary*)params
{
NSMethodSignature * methodSig = [target methodSignatureForSelector:action];
if(methodSig ==nil) {
returnnil;
}
constchar* retType = [methodSigmethodReturnType];
if(strcmp(retType,@encode(void)) ==0) {
NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:methodSig];
[invocation setArgument:¶msatIndex:2];
[invocations etSelector:action];
[invocation setTarget:target];
[invocation invoke];
return nil;
}
...
return [target performSelector:action withObject:params];
}
CTMediator+HandyTools 增加CTMediator的功能
模块分类 请求者
CTMediator+CTMediatorModuleAActions
- (UIViewController *)CTMediator_viewControllerForDetail;
外界调用分类CTMediator_viewControllerForDetail 就可以执行详情页
