weex更新方案探索（三） ——weex更新方案IOS端实现
前提
IOS工程配置信息，参考《第一个weex程序》中 配置IOS环境 的部分。
不同之处，本篇需要使用在线js文件，config.xml作如下修改：
<!--////////////////////////【重要】////////////////////////////////////--> <!-- 本地 或 在线资源 开关: true使用本地，false使用在线 --> <preference name="launch_locally" value="false" /><!--///////////////////////////////////////////////////////////////////--><!--////////////////////////【在线】////////////////////////////////////--> <!-- launch_locally:false 使用在线的资源：launch_url不为空，使用launch_url的启动地址；launch_url为空，使用online_start_url:+port --> <!-- 公网地址 --> <preference name="launch_url" value="http://www.xxx.com/xxx/dist/xxx/login/auto_login.js"/>目的
C端要实现公用缓存，下载、进度、解压，页面跳转，页面刷新，防篡改机制。
故在原项目WXEventModule中添加相应的方法提供B端调用。
B端如何与C端交互？
这任务就交给我吧——WXEventModule！！
添加以下方法，暴露给B端调用，需要注意的：涉及多次回调结果给B疯掉的，callback要定义为WXModuleKeepAliveCallback。
说明：
涉及到的：LoaderViewController，LandscapeLoaderViewController，是基于WXDemoViewController自定义的扩展横竖屏处理和url拼装等的ViewController，限于篇幅，本文不罗列。
涉及到的：Singleton.h，可自行谷歌或百度一下。
涉及到的：DownloadUtil，FileUtil，ZipUtil，本文会在后面篇幅贴出代码。

在C端定义整个app生命周期的变量，提供给B端，即可减轻weex大量的storage操作。
在AppDelegate.h中定义：
@property (strong, nonatomic) NSMutableDictionary *globelCaches;@property (strong, nonatomic) NSString *globelWebVersion;+(AppDelegate*)shareInstance;在AppDelegate.m中声明：
+ (AppDelegate *)shareInstance { return (AppDelegate *)[[UIApplication sharedApplication] delegate];}- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{ self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds]; self.window.backgroundColor = [UIColor whiteColor]; [WeexSDKManager setup]; [self.window makeKeyAndVisible]; // Override point for customization after application launch. self.globelCaches = [[NSMutableDictionary alloc]init]; return YES;}谁来帮忙下载？
交给DownloadUtil！！
下载辅助类，结合传参isUnzip，若只有一个zip文件下载，isUnzip=ture，则会进行解压操作处理，具体B端传参决定。
下载过程中，会回调进度给调用方。

ZipUtil
需要在pod中导入SSZipArchive
def common pod 'SSZipArchive'end具体代码：
//// ZipUtil.h//#import <Foundation/Foundation.h>#import "Singleton.h"typedef void(^ZipUtilBlock)(BOOL result);@interface ZipUtil : NSObjectAS_SINGLETON(ZipUtil)- (void)unzipFile:(NSString *)zipFile block:(ZipUtilBlock)block;@end//// ZipUtil.m// #import "ZipUtil.h"#import "FileUtil.h"#import "ZipArchive.h"//web目录名称static NSString *WEB_LOCAL_FOLDER = @"BRLF_WEB";@interface ZipUtil()@property (nonatomic) ZipUtilBlock zipBlock;@end@implementation ZipUtilDEF_SINGLETON(ZipUtil);- (void)unzipFile:(NSString *)zipFile block:(ZipUtilBlock)block { self.zipBlock = block; [self performSelector:@selector(start:) withObject:zipFile afterDelay:0.1];}- (void)start:(NSString *)zipFile { __weak ZipUtil *weakSelf = self; dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_BACKGROUND, 0), ^{ //解压zipFile到沙盒中 [weakSelf unzipFileToSandBox:zipFile]; });}/** * @author guoli, 17-10-19 16:10:34 * * @brief 解压zipFile到沙盒中 */- (void)unzipFileToSandBox:(NSString *)zipFile { NSString *webDir = WEB_LOCAL_FOLDER;// NSString *zipPath = [FileUtil getSandBoxFilePath: [NSString stringWithFormat:@"\%@", webDir] fileName:zipFile];// NSString *unzipPath = [FileUtil getSandBoxFilePath: [NSString stringWithFormat:@"\%@", webDir] fileName:@""]; NSString *zipPath = [FileUtil getSandBoxFilePath: @"" fileName:zipFile]; NSString *unzipPath = [FileUtil getSandBoxFilePath: [NSString stringWithFormat:@"\%@", webDir] fileName:@""]; BOOL result = [self unzipToPath:unzipPath zipPath:zipPath]; NSLog(@"解压:%@ %@", webDir, (result ? @"成功" : @"失败")); if (self.zipBlock) { self.zipBlock(result); }}/** * @author guoli, 17-10-19 18:10:29 * * @brief 解压指定压缩文件到指定路径 * @param unzipPath 解压后文件存放的路径 * @param zipPath 压缩文件的路径 * @return 解压成功 或 失败 */- (BOOL)unzipToPath:(NSString *)unzipPath zipPath:(NSString *)zipPath { BOOL result = NO; NSLog(@"zipPath=%@", zipPath); NSLog(@"unzipPath=%@", unzipPath); result = [SSZipArchive unzipFileAtPath:zipPath toDestination:unzipPath]; NSLog(@"解压操作：%@", (result ? @"成功" : @"失败")); return result;}@end附上扩展类：
