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；
<pre>- (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];
}</pre>
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
<pre>

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}" </pre>
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；
<pre>- (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;
} </pre>
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
<pre>- (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];
}
</pre>

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；

<pre>- (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];
}
} </pre>

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；
<pre>

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];
  }
  </pre>

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；
<pre>#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];
}
</pre>
更新本地数据
<pre>#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");
}
} </pre>
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；
<pre>#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");
}
} </pre>
d.效果图

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；
