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/${FMK_NAME}.framework
# Working dir will be deleted after the framework creation.
WRK_DIR=build
DEVICE_DIR=${WRK_DIR}/Release-iphoneos/${FMK_NAME}.framework
SIMULATOR_DIR=${WRK_DIR}/Release-iphonesimulator/${FMK_NAME}.framework
# -configuration ${CONFIGURATION}
# Clean and Building both architectures.
xcodebuild -configuration "Release" -target "${FMK_NAME}" -sdk iphoneos clean build
xcodebuild -configuration "Release" -target "${FMK_NAME}" -sdk iphonesimulator clean build
# Cleaning the oldest.
if [ -d "${INSTALL_DIR}" ]
then
rm -rf "${INSTALL_DIR}"
fi
mkdir -p "${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>
