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；

[objc] view plain copy







<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

[objc] view plain copy







<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；

[objc] view plain copy







- (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

[objc] view plain copy







- (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；

[objc] view plain copy







- (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];

}

}

c.效果图

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；

[objc] view plain copy







<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；

[objc] view plain copy







<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

[objc] view plain copy







<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；

[objc] view plain copy







<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；
