iOS 热更新，实时代码更新，动态更新，动态库framework

只要审核通过后，无须再次审核，就可以动态更新，iOS有三种处理方案：

一、开源框架 reactive native，但是编程语言是js

二、lua 脚本

三、使用oc语言的动态库framework。前两者，我不打算细讲，我主要介绍怎么用oc进行热更新

1、创建framework工程:

2、代码处理：

写一个controller的控制工具类：

//  HotUpdateControl.m
//  HotUpdateMudel

#import "HotUpdateControl.h"
#import "AController.h"
#import "BViewController.h"
#import "CViewController.h"
#import "DViewController.h"
#import "EViewController.h"
@implementation HotUpdateControl

-(NSArray *)getVcs {
    
    return @[
             [[AController alloc]init],
             [[BViewController alloc]init],
             [[CViewController alloc]init],
             [[DViewController alloc]init],
             [[EViewController alloc]init]];
    
}

@end

好了，开始打包framework,为了以免打包出来的framework,在真机上面运行不了，我们使用一个脚本来进行打包，目的是多型号CPU核心的合成，就是打出一个通用的包。

# 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}"

3、建立一个主项目，就是使用这些动态库的工程

现在进行读取离线包的测试，只要这个项目，能够从沙箱里面读取到代码文件，就意味着可以在线更新代码，远程升级！！！

动态库已经加载到了沙箱～～～
我修改了UITabBarController加载版块的初始化方法，如果沙箱有framework动态库，就加载framework动态库上面的版块，令到项目可以模块化

//
//  TabController.m
//  HotUpdate

#import "TabController.h"
//#import <HotUpdateMudel/HotUpdateControl.h>
@interface TabController ()

@end

@implementation TabController

-(instancetype)initWithCoder:(NSCoder *)aDecoder{
    if (self = [super initWithCoder:aDecoder]) {
        NSString *documentDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
        NSArray* arrFramework = [self getFilenamelistOfType:@"framework"  fromDirPath:documentDirectory];
        NSLog(@"%@",arrFramework);
        if (arrFramework.count==0) {
            NSArray * arrTitle = @[@"首页",@"广场",@"朋友圈",@"我的",@"设置"];
            NSMutableArray * arrVcs = @[].mutableCopy;
            for (int i=0; i<arrTitle.count; i++) {
                UIViewController * vcRoot = [[UIViewController alloc]init];
                vcRoot.title = arrTitle[i];
                vcRoot.view.backgroundColor = [UIColor whiteColor];
                UINavigationController * navi = [[UINavigationController alloc]initWithRootViewController:vcRoot];
                [arrVcs addObject:navi];
            }
            [self setViewControllers:arrVcs animated:YES];
            
        }else{
            
            NSString *bundlePath = [NSString stringWithFormat:@"%@/%@",documentDirectory,[arrFramework lastObject]];
            
            if (![[NSFileManager defaultManager] fileExistsAtPath:bundlePath]) {
                NSLog(@"file not exist ,now  return");
                return self;
            }
            NSBundle *bundle = [NSBundle bundleWithPath:bundlePath];
            
            if (!bundle || ![bundle load]) {
                NSLog(@"bundle load error");
            }
            
            Class loadClass = [bundle classNamed:@"HotUpdateControl"];
            if (!loadClass) {
                NSLog(@"get bundle class fail");
                return self;
            }
            NSObject *bundleObj = [loadClass new];
            NSArray * arrVc = [bundleObj performSelector:@selector(getVcs)];
            
            NSMutableArray * arrVcs = @[].mutableCopy;
            for (int i=0; i<arrVc.count; i++) {
                UIViewController * vcRoot =arrVc[i];
                vcRoot.view.backgroundColor = [UIColor whiteColor];
                UINavigationController * navi = [[UINavigationController alloc]initWithRootViewController:vcRoot];
                [arrVcs addObject:navi];
            }
            
            [self setViewControllers:arrVcs animated:YES];
            
        }
    }
    return self;
}

-(NSArray *) getFilenamelistOfType:(NSString *)type fromDirPath:(NSString *)dirPath
{
    NSArray *fileList = [[[NSFileManager defaultManager] contentsOfDirectoryAtPath:dirPath error:nil]
                         pathsMatchingExtensions:[NSArray arrayWithObject:type]];
    return fileList;
}

- (void)viewDidLoad {
    [super viewDidLoad];
    
}


@end  

看结果了，如果是本地的默认版本，应该是
@[@"首页",@"广场",@"朋友圈",@"我的",@"设置"];的模块
但是如果是沙箱里面的模块
那么久应该ABCDE
