早期 iCome iOS客户端设计

简书部分流程图看不到,可移步

应用启动的主要流程

st=>start: AppDelegate
islogin=>condition: isLogin?
login=>operation: http登录
tcp=>operation: tcp注册登录
newdesc=>operation: 功能引导
rootVC=>operation: 主控制器
mainVC=>operation: 主页
sync=>operation: 数据同步

e=>end



st->islogin
islogin(yes)->tcp->rootVC->e
islogin(no)->newdesc->login(left)->tcp->rootVC->mainVC->sync->e

1. 整体架构与模块化划分设计

项目采用Category方式设计把项目按照某个具体业务逻辑功能划分、采用中间调度模块IComMediator管理输入与回调内容进行模块化解耦

#import <Foundation/Foundation.h>
typedef void (^IComMediatorObjectHandler)(id result);
@interface IComMediator : NSObject
+(instancetype)sharedInstance;
// 远程App调用入口
- (id)performActionWithUrl:(NSURL *)url completion:(void(^)(NSDictionary *info))completion;

// 本地组件调用入口
- (id)performTarget:(NSString *)targetName action:(NSString *)actionName params:(NSDictionary *)params;

// 充分模块化解耦 存储block用页面跳转调用
- (id)performTarget:(NSString *)targetName action:(NSString *)actionName params:(NSDictionary *)params completion:(IComMediatorObjectHandler)completion;
// 所有b页面回调
- (void)toHandlerTargetName:(NSString *)targetName action:(NSString *)actionName param:(id)param;

@end

项目文件结构

项目文件结构.png

每一个模块文件结构相同,模块中的Actions与Category 负责本模块的功能被调度

项目文件结构展开.png

    #import "IComMediator+DynamicModuleActions.h"
    // action 类名 Dynamic 模块统一用Dynamic 模块名
    NSString * const kIComMediatorTargetDynamic = @"Dynamic";
    // 类对应方法名 一个模块下不同控制器的类名
    NSString * const kIComNativeFetchDynamicViewController = @"nativeFetchDynamicViewController";
    NSString * const kIComNativeFetchDiscoverViewController = @"nativeFetchDiscoverViewController";
    //DiscoverViewController

    @implementation IComMediator (DynamicModuleActions)
    - (UIViewController *)IComMediator_DynamicViewController:(NSDictionary *)params {
    UIViewController *viewController = [self performTarget:kIComMediatorTargetDynamic
                                                    action:kIComNativeFetchDynamicViewController
                                                    params:params];
    if ([viewController isKindOfClass:[UIViewController class]]) {
        // view controller 交付出去之后,可以由外界选择是push还是present
        return viewController;
    } else {
        // 这里处理异常场景,具体如何处理取决于产品
        return [[UIViewController alloc] init];
    }
    }

- (UIViewController *)IComMediator_DiscoverViewController:    (NSDictionary *)params
    {
    UIViewController *viewController = [self performTarget:kIComMediatorTargetDynamic
                                                    action:kIComNativeFetchDiscoverViewController
                                                    params:params];
    if ([viewController isKindOfClass:[UIViewController class]]) {

        return viewController;
    } else {
        return [[UIViewController alloc] init];
    }
    }
    @end

公共部分负责项目每个模块的整体调度与协作

负责公共部分.png

每个模块的Category调度器均为主调度器(IComMediator)的Category

IComMediator.h

#import <Foundation/Foundation.h>

@interface IComMediator : NSObject

+(instancetype)sharedInstance;

// 远程App调用入口
- (id)performActionWithUrl:(NSURL *)url completion:(void(^)(NSDictionary *info))completion;

// 本地组件调用入口
- (id)performTarget:(NSString *)targetName action:(NSString *)actionName params:(NSDictionary *)params;

@end

IComMediator.m

    #import "IComMediator.h"
    #import "NSDictionary+URL.h"

    @implementation IComMediator
    +(instancetype)sharedInstance {
    static IComMediator *mediator;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        mediator = [[IComMediator alloc] init];
    });
    return mediator;
    }

    // 远程App调用入口
    - (id)performActionWithUrl:(NSURL *)url completion:(void(^)(NSDictionary *info))completion {
    if (![url.scheme isEqualToString:@"icom"]) { // 外部启动规则
        // 这里就是针对远程app调用404的简单处理了
        return @(NO);
        }

    NSDictionary *params = [NSDictionary dictionaryWithURLQuery:[url query]];
    
    NSString *actionName =
    [url.path stringByReplacingOccurrencesOfString:@"/" withString:@""];
    
    id result = [self performTarget:url.host action:actionName params:params];
    if (completion) {
        if (result) {
            completion(@{ @"result" : result });
        } else {
            completion(nil);
        }
    }
    return result;
    }

    // 本地组件调用入口
    - (id)performTarget:(NSString *)targetName action:(NSString *)actionName params:(NSDictionary *)params {
    // 运行时方式 让对应的目标类执行对应的目标方法
    NSString *targetClassString =
    [NSString stringWithFormat:@"Target_%@", targetName];
    NSString *actionString =
    [NSString stringWithFormat:@"Action_%@:", actionName];
    
    Class targetClass = NSClassFromString(targetClassString);
    id target = [[targetClass alloc] init];
    SEL action = NSSelectorFromString(actionString);
    
    if (target == nil) {
        // 这里是处理无响应请求的地方之一,这个demo做得比较简单,如果没有可以响应的target,就直接return了。实际开发过程中是可以事先给一个固定的target专门用于在这个时候顶上,然后处理这种请求的
        return nil;
        }
    
    if ([target respondsToSelector:action]) {
    #pragma clang diagnostic push
    #pragma clang diagnostic ignored "-Warc-performSelector-leaks"
        return [target performSelector:action withObject:params];
    #pragma clang diagnostic pop
    } else {
        // 这里是处理无响应请求的地方,如果无响应,则尝试调用对应target的notFound方法统一处理
        SEL action = NSSelectorFromString(@"notFound:");
        if ([target respondsToSelector:action]) {
    #pragma clang diagnostic push
    #pragma clang diagnostic ignored "-Warc-performSelector-leaks"
            return [target performSelector:action withObject:params];
    #pragma clang diagnostic pop
        } else {
            // 这里也是处理无响应请求的地方,在notFound都没有的时候,这个demo是直接return了。实际开发过程中,可以用前面提到的固定的target顶上的。
            return nil;
        }
    }
    }

模块间调度

    UIViewController *viewController = [[IComMediator sharedInstance]         
    IComMediator_DiscoverViewController:nil];
    [self.navigationController pushViewController:viewController animated:YES];

模块注册 每个模块注册IComMediator的Category后声明需要提供外部模块调用的类

#import "IComMediator+DynamicModuleActions.h"
// action 类名 Work 模块统一用Work
NSString * const kIComMediatorTargetDynamic = @"Dynamic";

// 类对应方法名
NSString * const kIComNativeFetchDynamicViewController = @"nativeFetchDynamicViewController";
NSString * const kIComNativeFetchDiscoverViewController = @"nativeFetchDiscoverViewController";
//DiscoverViewController


@implementation IComMediator (DynamicModuleActions)
- (UIViewController *)IComMediator_DynamicViewController:(NSDictionary *)params {
    UIViewController *viewController = [self performTarget:kIComMediatorTargetDynamic
                                                    action:kIComNativeFetchDynamicViewController
                                                    params:params];
    if ([viewController isKindOfClass:[UIViewController class]]) {
        // view controller 交付出去之后,可以由外界选择是push还是present
        return viewController;
    } else {
        // 这里处理异常场景,具体如何处理取决于产品
        return [[UIViewController alloc] init];
    }
}

##2. TCP连接模块设计

![B215DD52-0EB9-4EA8-B342-CA7DCAB4C0F5.png](http://upload-images.jianshu.io/upload_images/1775503-da62d481d2c5d647.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240)

```flow
st=>start: TCP登录
islogin=>condition: TCP登录成功?
sendBeat=>operation: 创建轮询发送心跳请求
sendBeatStatus=>condition: 心跳包发送成功?
reSendBeat=>operation: 重新发送机制
isbeatFailOut=>condition: 失败次数超限?
reSendF=>operation: 失败次数达到上限后判断是否断开连接,做相应处理


reConnect=>operation: tcp断开重新连接机制
reIsSuccess=>condition: 重连接机?
disConnect=>condition: 断开连接?
alert=>operation: 提示用户无法正常连接

login=>operation: http登录
tcp=>operation: tcp注册登录
newdesc=>operation: 功能引导
rootVC=>operation: 主控制器
mainVC=>operation: 主页

e=>end

st->islogin
islogin(yes)->sendBeat->sendBeatStatus(yes)->e
sendBeatStatus(no)->isbeatFailOut(yes,right)->reConnect
isbeatFailOut(no)->e
disConnect(no,bottom)->e
islogin(no)->reConnect(right)->reIsSuccess
reIsSuccess(yes,left)->sendBeat
reIsSuccess(no)->alert->e

3. iCome数据同步机制流程

B3EBE84C-9FF0-47C6-99F7-F9300C91CBF9.png

st=>start: TCP登录成功
sync=>operation: imserver/groupList
syncStatus=>condition: grouplist?
saveDB=>operation: 修改(状态、未读数等)
updateGroupInfo=>operation: 更新群组信息
saveDB2=>operation: 存储群组最新消息
syncCmd=>operation: imserver/cmdList
syncCmdStatus=>condition: cmdList?
updateStatus=>operation: 同步本地的信息(修改头像、踢出群组、日程同步等)

e=>end
st->sync->syncStatus(yes)->saveDB->updateGroupInfo->saveDB2->syncCmd->updateStatus->e
syncStatus(no)->e

4. 消息发送机制

st=>start: 用户输入
isFile=>condition: file?
checkFile=>condition: 服务器存在?
createMessage=>operation: 创建消息体、生成消息唯一标识

sendFile=>operation: 创建临时消息体,发送文件拿到filekey

saveDB=>operation: 消息存储

sendMessage=>operation: 更新UI界面,消息发送
isSuccess=>condition:  消息发送成功?

disConnect=>condition: tcp连接?

update=>operation: 更新DB和UI
sendFail=>operation: 更新UI
sysReSend=>operation: tcp重新连接后系统重新发送

isTimeOut=>condition: 消息发送超时?
e=>end

st->isFile
isFile(yes)->checkFile
isFile(no)->createMessage->saveDB->sendMessage->disConnect(yes)->isSuccess
checkFile(yes,right)->createMessage
checkFile(no)->sendFile->createMessage
disConnect(no)->isTimeOut(no)->sysReSend->isSuccess
isTimeOut(yes)->sendFail
isSuccess(no)->sendFail->e
isSuccess(yes,right)->update->e

5.消息接收机制

进入聊天模块调用

st=>start
loadData=>operation: 本地数据库加载数据
cheak=>condition: db.lastId-db.firstId>=max?
repullMessage=>operation: repullMessage
saveDB=>operation: save DB
update=>operation: 更新UI界面
e=>end


st->loadData->cheak
cheak(yes)->repullMessage->saveDB->update->e
cheak(no)->update->e

消息返拉逻辑调用

st=>start
loadData=>operation: 本地数据库加载数据(data.firstId)
cheakCount=>condition: count>0?
cheak=>condition: data.firstId-db.firstId>=max?
repullMessage=>operation: repullMessage
cheakMaxId=>condition: maxId == nil?
isLastId=>condition: 最后一条数据?
update=>operation: 更新UI界面
e=>end

st->loadData->cheakCount
cheakCount(yes)->cheak
cheakCount(no)->cheakMaxId
cheakMaxId(yes)->repullMessage
cheakMaxId(no)->isLastId
isLastId(yes, right)->update
isLastId(no)->repullMessage
cheak(yes)->repullMessage->update->e
cheak(no)->update->e

消息接收逻辑调用

st=>start
tcpReceived=>operation: messageDidReceived
cmd=>condition: isCmd ?
updateCmd=>operation: updateCmdList
cmdListAction=>operation: 处理对应action
cheak=>condition: messageType == 0
groupList=>operation: updateGroupList
isExist=>condition: groupIsExist?
updateGroupStatus=>operation: 更新状态、未读、声音提示等信息
saveDB=>operation: 消息存储到本地数据库
update=>operation: 通知更新聊天与消息列表界面
e=>end


st->tcpReceived->cmd
cmd(yes,right)->updateCmd->cmdListAction->e
cmd(no)->cheak
cheak(yes, right)->groupList->e
cheak(no)->isExist
isExist(yes)->updateGroupStatus->saveDB->update->e
isExist(no)->groupList->e

6. 数据存储

C6CB068E-0EA6-4AA7-BD03-6F3DC90781CD.png

7. JS与WKWebView交互模块

st=>start: 协议定制
jsrequest=>operation: js请求
isBase=>condition: 基础接口?
isValidData=>condition: ValidData?
validData=>operation: 权限校验
hasPermission=>condition: 权限?
load=>operation: 调用客户端逻辑
loadSuccess=>condition: isSuccess?
success=>operation: 成功回调
fail=>operation: 错误回调

e=>end
st->jsrequest->isBase
isBase(yes)->load->loadSuccess
isBase(no)->hasPermission
hasPermission(yes)->load
hasPermission(no)->validData->loadSuccess
loadSuccess(yes)->success->e
loadSuccess(no)->fail->e

8. 页面统一调用逻辑

通过URL Router方式处理原生、网页、weex页面的调用

- (void)pushCustomViewControllerURL:(NSString *)URL
                 fromViewController:(UIViewController *)ViewController
                           animated:(BOOL)animated {
                           if ([URL hasPrefix:@"icome"]) { // 打开本地自定义界面
        NSString *tempUrl = [URL stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
        NSURL *pushUrl = [NSURL URLWithString:tempUrl];
        NSString *scheme = pushUrl.scheme;
        NSString *host = pushUrl.host;
        NSString *path = pushUrl.path;
        NSString *query = pushUrl.query;
        
        NSDictionary *queryDict = nil;
        if (!kStringIsEmpty(query)) {
            queryDict = [NSDictionary dictionaryWithURLQuery:query];
        }
        NSString *coustId = nil;
        if (!kStringIsEmpty(path)) {
            coustId = [[path componentsSeparatedByString:@"/"] objectAtIndex:1]; //
        }
        
        NSString *class = host;
        // 日程
        if ([class isEqualToString:@"schedule"]) {
            NSDictionary *param = nil;
            if (!kStringIsEmpty(queryDict[@"beginDate"])) {
                param = @{@"beginDate":queryDict[@"beginDate"]};
            }
            UIViewController *viewController = [[IComMediator sharedInstance] IComMediator_CalendarViewController:param];
            [ViewController.navigationController pushViewController:viewController animated:YES];
        }
        
 }

9. 第三方使用

source 'https://github.com/CocoaPods/Specs.git' platform :ios, '8.0'

target 'ICome' do

pod 'FMDB', '~> 2.6.2'
pod 'MBProgressHUD',    '~> 1.0.0'
pod 'Masonry',  '~> 1.0.2'
pod 'SDWebImage',   '~> 3.7.6' #修改过源代码 请勿更新
pod 'CocoaAsyncSocket', '~> 7.4.3'
pod 'SSKeychain',   '~> 1.4.0'
pod 'MJExtension',  '~> 3.0.10'
pod 'YYKit',    '~> 1.0.5' #修改过源代码 请勿更新
pod 'MLLabel',  '~> 1.9.1' #修改过源代码 请勿更新
pod 'UITableView+FDTemplateLayoutCell', '~> 1.4'
pod 'AFNetworking', '~> 3.1.0'
pod 'BaiduMapKit',  '~> 3.3.1'
pod 'MJRefresh',    '~> 3.1.12'
pod 'UMengAnalytics',   '~> 4.2.4'
pod 'FDFullscreenPopGesture',   '~>1.1'
pod 'CYLTabBarController',  '~> 1.6.0' #修改过源代码 请勿更新
pod 'CocoaLumberjack',  '~> 3.0.0' #修改过源代码 请勿更新
pod 'JSPatchPlatform', '~> 1.6.4'
pod 'TZImagePickerController',  '1.7.9'  #修改过源代码 请勿更新
pod 'mailcore2-ios', '0.6.4'
pod 'DKNightVersion', '2.4.3'
pod 'LKDBHelper', '2.4.2'
pod 'Bugtags'

end

10. 后期架构调整

邮箱登录逻辑

st=>start: 进入邮箱界面
sync=>operation: 默认邮箱地址进行登录
syncStatus=>condition: 邮箱登录成功?

saveDB=>operation: 保存邮箱地址与密码供下次登录
mailLogin=>operation: 邮箱登录界面
userEdt=>operation: 用户编辑邮箱信息登录
check=>condition: 本地校验邮箱格式?
login=>operation: 登录中..
loginStatus=>condition: 第二次登录是否成功?
traverseLogin=>operation: 遍历登录邮箱...

e=>end


st->sync->syncStatus(yes, right)->saveDB->e
syncStatus(no)->mailLogin->userEdt->check(yes)->login->loginStatus(yes)->saveDB->e


check(no)->userEdt
loginStatus(no)->traverseLogin->saveDB->e
