随着公司的业务越来越多，项目也越来越大，项目耦合也越来越严重。传统的MVC模式已经解决不了问题，组件化势在必行。组件化可以使你的项目变成一个个组件，除了依赖于公共组件，其他每个组件都可以和新的组件组成新的app，这样大大减少了工作量。本文主要采用的是CTMediator的组件化方案。CTMediator源码链接
CTMediator采用的是target-action的方式，通过runtime的反射机制来获取类和方法。
demo链接组件化
首先创建模块分类CTMediator+live.h
.m中的实现
特别注意Target_后的模块名和constkXMMediatorTargetLive的值一定要绝对一致
#import "CTMediator+live.h"
// target 模块名称，对应Action类名后缀，一定要一样！Target_Live.h
NSString*constkXMMediatorTargetLive =@"Live";
NSString*constkXMMediatorActionNativeFetchLiveHomePageController =@"NativeFetchLiveHomePageController";
NSString*constkXMMediatorActionNativeFetchLiveChannelController =@"NativeFetchLiveChannelController";
@implementation CTMediator (live)
- (UIViewController *)XMMediator_viewControllerForLiveHomePage {
UIViewController *viewController = [self performTarget:kXMMediatorTargetLive
action:kXMMediatorActionNativeFetchLiveHomePageController
params:nil
shouldCacheTarget:NO];
if([viewControllerisKindOfClass:[UIViewControllerclass]])
{
returnviewController;
}
else
{
return[[UIViewControlleralloc]init];
}
}
- (UIViewController *)XMMediator_viewControllerForLiveWatchPage:(NSDictionary *)params {
UIViewController *viewController = [self performTarget:kXMMediatorTargetLive
action:kXMMediatorActionNativeFetchLiveChannelController
params:params
shouldCacheTarget:NO];
if([viewControllerisKindOfClass:[UIViewControllerclass]])
{
returnviewController;
}
else
{
return[[UIViewControlleralloc]init];
}
}
@end
然后创建Target_Live.h
.m中实现
注意如果你的参数不用这么复杂可以不用下面的私有方法，跟官方一样简单就好，根据自己的实际需求来
#import "Target_Live.h"
#import
@implementation Target_Live
- (UIViewController *)Action_NativeFetchLiveHomePageController:(NSDictionary *)params {
return [self viewControllerForString:@"XMLiveHomePageController" params:params];
}
- (UIViewController *)Action_NativeFetchLiveChannelController:(NSDictionary *)params {
return [self viewControllerForString:@"XMLiveChannelController" params:params];
}
#pragma mark- private
/// 给vc赋值参数
- (UIViewController *)viewControllerForString:(NSString *)vcStr params:(NSDictionary *)params {
Classcls =NSClassFromString(vcStr);
UIViewController*temInstance = [[clsalloc]init];
if([temInstanceisKindOfClass:[UIViewControllerclass]]) {// 严谨判断 是viewcontroller or子类
if(params) {
[selfupdateParam:paramsforInstance:temInstance];
}
returntemInstance;
}
return nil;
}
/// 给对象赋值参数
- (void)updateParam:(NSDictionary*)paramsforInstance:(NSObject*)obj {
NSDictionary*objProperties = [selfpropertyFroObj:obj];
for(NSString*keyinparams.allKeys) {
if([objPropertiesvalueForKey:key]) {
[objsetValue:params[key]forKey:key];
}else{
NSLog(@"XMSport Router Warning( Live sectoin) : 跳转对象没有该属性 %@ %@", obj, key);
}
}
}
/// 获取obj的所有属性
- (NSDictionary *)propertyFroObj:(NSObject *)obj {
NSMutableDictionary *propertiesDic = [NSMutableDictionary dictionary];
unsignedintpropertyCount =0;
objc_property_t*properties =class_copyPropertyList([objclass], &propertyCount);
for(intidx =0; idx
objc_property_tproperty = properties[idx];
NSString *propertyName = [[NSString alloc] initWithCString:property_getName(property) encoding:NSUTF8StringEncoding];
[propertiesDicsetValue:@1forKey:propertyName];
}
free(properties);
return[propertiesDiccopy];
}
@end
最后调用
UIViewController*viewController = [[CTMediator sharedInstance] XMMediator_viewControllerForLiveHomePage];
[self.navigationController pushViewController:viewController animated:YES]; CTMediator的问题在于你如果只是做一个小的项目，完全用不着组件化，小项目只会增加更多的工作量，另外组件化也可以搭配mvc和MVVM等其他设计模式使用。
另一个问题在于传递参数的时候，有硬编码。这就需要开发人员有较高的技艺，需要细心，不然容易出现找不到值的问题，甚至产生运行时错误。
