iOS-OC-APP热更新,动态更新(仿QQ打开或关闭某个功能)

一.前言

iOS开发更新APP我觉得是比较坑的就是审核时间比较长，审核比较严，对于刚入行的小伙伴来说，雷区比较多；所以热更新是比较重要的；

大家也许会发现我们常用的QQ现在下来也就一百多兆，但是用了几个月后发现QQ在手机上占有一个多G的内存，特别是手机内存比较小的小伙伴，这是因为你在使用过程中，有一些功能是你下载下来的；

二.创建Framework

1.新建项目

新建一个Cocoa Touch Framework项目，然后在这个项目里面写你的新的功能，比如我创建了一个控制器，在控制器里面加载一张图和一个label；

<span style="font-size:18px;">- (void)uiConfig{    self.title = @"这是功能2";        UIImageView *imageView = [[UIImageView alloc]init];    imageView.frame = CGRectMake(0, 0, ScreenWidth, ScreenHeight);    NSData *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:@"http://img4.duitang.com/uploads/item/201405/31/20140531174207_hH5u4.thumb.700_0.jpeg"]];    imageView.image = [UIImage imageWithData:data];    [self.view addSubview:imageView];        UILabel *label = [[UILabel alloc]init];    label.backgroundColor = [UIColor clearColor];    label.frame = CGRectMake(0, (ScreenHeight - 100)/2, ScreenWidth, 100);    label.numberOfLines = 0;    label.text = @"这是功能2这是功能2这是功能2这是功能2这是功能2这是功能2这是功能2这是功能2这是功能2这是功能2这是功能2这是功能2这是功能2这是功能2这是功能2";    [self.view addSubview:label];}</span>

2.添加Aggregate

在TARGETS里面新建一个Aggregate

3.添加Run Script脚本

4.脚本源码

<span style="font-size:18px;"># Sets the target folders and the final framework product.# 如果工程名称和Framework的Target名称不一样的话，要自定义FMKNAME# 例如: FMK_NAME = "MyFramework"FMK_NAME=${PROJECT_NAME}# Install dir will be the final output to the framework.# The following line create it in the root folder of the current project.INSTALL_DIR=${SRCROOT}/Products/${FMK_NAME}.framework# Working dir will be deleted after the framework creation.WRK_DIR=buildDEVICE_DIR=${WRK_DIR}/Release-iphoneos/${FMK_NAME}.frameworkSIMULATOR_DIR=${WRK_DIR}/Release-iphonesimulator/${FMK_NAME}.framework# -configuration ${CONFIGURATION}# Clean and Building both architectures.xcodebuild -configuration "Release" -target "${FMK_NAME}" -sdk iphoneos clean buildxcodebuild -configuration "Release" -target "${FMK_NAME}" -sdk iphonesimulator clean build# Cleaning the oldest.if [ -d "${INSTALL_DIR}" ]thenrm -rf "${INSTALL_DIR}"fimkdir -p "${INSTALL_DIR}"cp -R "${DEVICE_DIR}/" "${INSTALL_DIR}/"# Uses the Lipo Tool to merge both binary files (i386 + armv6/armv7) into one Universal final product.lipo -create "${DEVICE_DIR}/${FMK_NAME}" "${SIMULATOR_DIR}/${FMK_NAME}" -output "${INSTALL_DIR}/${FMK_NAME}"rm -r "${WRK_DIR}"open "${INSTALL_DIR}"</span>

5.运行打包

运行工程，将生成的framework包压缩zip，然后上传服务器；

例如：http://7xqdun.com1.z0.glb.clouddn.com/FunctionZFJ1.framework.zip

三.创建项目

在项目中我们主要是下载和读取framework包；我们先要获取功能列表，在此我在本地写了一个功能列表，大家如果用得到可以将功能列表存放在服务器上；

1.创建功能列表数据

我添加了四个功能模块，存在NSUserDefaults里面；其中功能1和功能2有下载地址，其他的没有；功能1是个NSObject，功能2直接是一个控制器；

isopen：1表示打开，0表示关闭；

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    // Override point for customization after application launch.    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];    self.window.backgroundColor = [UIColor whiteColor];    [self.window makeKeyAndVisible];        //添加假的功能列表    NSArray *functionList = [USER_DEFAULT objectForKey:@"functionList"];    if(functionList==nil || functionList.count==0){        NSArray *titleArr  = @[@"功能1",@"功能2",@"功能3",@"功能4"];        NSArray *className = @[@"HotUpdateControl",@"ZFJViewController",@"",@""];        NSArray *classType = @[@"NSObject",@"UIViewController",@"",@""];        NSArray *downUrl   = @[                               @"http://7xqdun.com1.z0.glb.clouddn.com/HotMudel.framework.zip",                               @"http://7xqdun.com1.z0.glb.clouddn.com/FunctionZFJ1.framework.zip",                               @"",                               @""];        NSMutableArray *functionArr = [[NSMutableArray alloc]init];        for (int i = 0; i<titleArr.count; i++) {            NSMutableDictionary *dict = [[NSMutableDictionary alloc]init];            [dict setObject:titleArr[i] forKey:@"name"];            [dict setObject:className[i] forKey:@"classname"];            [dict setObject:classType[i] forKey:@"classtype"];            [dict setObject:@(i) forKey:@"mid"];            [dict setObject:@"0" forKey:@"isopen"];//0 未开启  1开启了            [dict setObject:downUrl[i] forKey:@"downurl"];            [functionArr addObject:dict];        }        [USER_DEFAULT setObject:functionArr forKey:@"functionList"];        [USER_DEFAULT synchronize];    }        DynamicViewController *dvc = [[DynamicViewController alloc]init];    UINavigationController *nvc = [[UINavigationController alloc]initWithRootViewController:dvc];    self.window.rootViewController = nvc;        return YES;}

2.展示功能列表

在功能列表主要用于展示所有打开过的功能，也就是isopen为1的所有功能；

a.获取本地所有打开的数据，然后在tableview上显示

- (void)getDataBase{    [self.dataArray removeAllObjects];    NSArray *functionList = [USER_DEFAULT objectForKey:@"functionList"];    for (NSDictionary *dict in functionList) {        NSInteger isopen = [dict[@"isopen"] integerValue];        if(isopen==1){            [self.dataArray addObject:dict];        }    }    [self.tableview reloadData];}

b.点击对于的tableviewcell 的时候跳转对应的framework读取出来的方法

注意，我将不同的framework存放在不同的文件夹下，以mid作为区分；

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{    [tableView deselectRowAtIndexPath:indexPath animated:YES];    NSDictionary *dict = self.dataArray[indexPath.row];    //获取framework的路径名，我已mid区分    NSString *destinationPath = [NSHomeDirectory() stringByAppendingString:[NSString stringWithFormat:@"/Documents/FunctionZFJ%@",dict[@"mid"]]];    NSArray* arrFramework = [self getFilenamelistOfType:@"framework" fromDirPath:destinationPath];    NSString *bundlePath = [NSString stringWithFormat:@"%@/%@",destinationPath,[arrFramework lastObject]];    if (![[NSFileManager defaultManager] fileExistsAtPath:bundlePath]) {        NSLog(@"文件不存在");        return;    }        NSBundle *bundle = [NSBundle bundleWithPath:bundlePath];    if (!bundle || ![bundle load]) {        NSLog(@"bundle加载出错");    }        NSString *className = dict[@"classname"];    NSString *classtype = dict[@"classtype"];        Class loadClass = [bundle classNamed:className];    if (!loadClass) {        NSLog(@"获取失败");        return;    }        if([classtype isEqualToString:@"NSObject"]){        NSObject *bundleObj = [loadClass new];        NSArray *arrVc = [bundleObj performSelector:@selector(getVcs)];        TabController *tvc = [[TabController alloc]initwithVcArray:arrVc];        [self.navigationController pushViewController:tvc animated:YES];    }else if([classtype isEqualToString:@"UIViewController"]){        UIViewController *uvc = (UIViewController *)[loadClass new];        [self.navigationController pushViewController:uvc animated:YES];    }}

3.更多功能

在这里我们可以打开或者关闭某个功能；

a.获取所以功能，包括打开或者关闭状态的；然后在tableview上显示；

<span style="font-size:18px;">#pragma mark - 获取全部数据- (void)getDataBase{    [self.dataArray removeAllObjects];        NSArray *functionList = [USER_DEFAULT objectForKey:@"functionList"];    NSMutableArray *openYES = [[NSMutableArray alloc]init];    NSMutableArray *openNO = [[NSMutableArray alloc]init];    for (NSDictionary *dict in functionList) {        NSMutableDictionary *muDict = [[NSMutableDictionary alloc]initWithDictionary:dict];        NSInteger isopen = [muDict[@"isopen"] integerValue];        if(isopen==1){            //已经打开的功能            [openYES addObject:muDict];        }else{            //没有打开的功能            [openNO addObject:muDict];        }    }        [self.dataArray addObject:openNO];    [self.dataArray addObject:openYES];        [self.tableview reloadData];}</span>

b.打开功能

打开某个功能就是下载对应的framework，把下载下来的zip包进行解压一下然后获取到framework，接着删除zip包，把framework放在对于的目录下；最后改变本地列表功能的状态；

<span style="font-size:18px;">#pragma mark - 开启某个功能 先下载数据- (void)SSZipArchiveDataBaseWithDict:(NSMutableDictionary *)dict{    NSString *requestURL = dict[@"downurl"];    if(requestURL==nil || requestURL.length==0){        self.progresslabel.text = [NSString stringWithFormat:@"%@-没有下载地址,不能开启!",dict[@"name"]];        UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"提示" message:@"没有下载地址，不能开启" preferredStyle:UIAlertControllerStyleAlert];        UIAlertAction *sureBtn = [UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:nil];        [alertController addAction:sureBtn];        [self presentViewController:alertController animated:YES completion:nil];        return;    }    //下载保存的路径    NSString *savedPath = [NSHomeDirectory() stringByAppendingString:[NSString stringWithFormat:@"/Documents/FunctionZFJ%@.framework.zip",dict[@"mid"]]];    AFHTTPRequestSerializer *serializer = [AFHTTPRequestSerializer serializer];    NSMutableURLRequest *request = [serializer requestWithMethod:@"POST" URLString:requestURL parameters:nil error:nil];    AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc]initWithRequest:request];    [operation setOutputStream:[NSOutputStream outputStreamToFileAtPath:savedPath append:NO]];    [operation setDownloadProgressBlock:^(NSUInteger bytesRead, long long totalBytesRead, long long totalBytesExpectedToRead) {        float progress = (float)totalBytesRead / totalBytesExpectedToRead;        self.progresslabel.text = [NSString stringWithFormat:@"%@下载进度:%.2f",dict[@"name"],progress];    }];    [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {        NSLog(@"下载成功");        NSString *destinationPath = [NSHomeDirectory() stringByAppendingString:[NSString stringWithFormat:@"/Documents/FunctionZFJ%@",dict[@"mid"]]];        //对下载下来的ZIP包进行解压        BOOL isScu = [SSZipArchive unzipFileAtPath:savedPath toDestination:destinationPath];        if(isScu){            NSLog(@"解压成功");            NSFileManager *fileMgr = [NSFileManager defaultManager];            BOOL bRet = [fileMgr fileExistsAtPath:savedPath];            if (bRet) {                [fileMgr removeItemAtPath:savedPath error:nil];//解压成功后删除压缩包            }            [dict setValue:@"1" forKey:@"isopen"];            [self updataBaseWithDict:dict];//解压成功后更新本地功能列表状态        }else{            NSLog(@"解压失败 --- 开启失败");        }            } failure:^(AFHTTPRequestOperation *operation, NSError *error) {        NSLog(@"下载失败 --- 开启失败");            }];    [operation start];}</span>

更新本地数据

<span style="font-size:18px;">#pragma mark - 更新本地数据- (void)updataBaseWithDict:(NSMutableDictionary *)dict{    NSInteger mid = [dict[@"mid"] integerValue];    NSMutableArray *functionList = [USER_DEFAULT objectForKey:@"functionList"];    NSMutableArray *dataArr = [[NSMutableArray alloc]initWithArray:functionList];    [dataArr replaceObjectAtIndex:mid withObject:dict];    [USER_DEFAULT setObject:dataArr forKey:@"functionList"];    BOOL isScu = [USER_DEFAULT synchronize];    if(isScu){        [self getDataBase];//重新获取数据 更新列表        if(self.refreshData){            self.refreshData();        }    }else{        NSLog(@"c操作失败");    }}</span>

c.关闭功能

关闭某个功能，也就是删除某个功能的framework，然后更改功能列表的状态；

<span style="font-size:18px;">#pragma mark - 关闭某个功能- (void)delectFunctionZFJWithDict:(NSMutableDictionary *)dict{    NSFileManager *fileMgr = [NSFileManager defaultManager];    NSString *savedPath = [NSHomeDirectory() stringByAppendingString:[NSString stringWithFormat:@"/Documents/FunctionZFJ%@",dict[@"mid"]]];    BOOL bRet = [fileMgr fileExistsAtPath:savedPath];    if (bRet) {        NSError *err;        //关闭某个功能 就是删除本地的framework  然后修改本地功能状态        BOOL isScu = [fileMgr removeItemAtPath:savedPath error:&err];        if(isScu){            [dict setValue:@"0" forKey:@"isopen"];            [self updataBaseWithDict:dict];        }else{            NSLog(@"关闭失败");        }    }else{        NSLog(@"关闭失败");    }}</span>

四.源代码

在这里面有，两个framework的源代码，可项目的代码；

注意，如果有多个功能的framework，记住多个framework的命名在同一个功能里面不能重复，不然调取失败；
