1、有远程zip下载链接的可以跳过这一步（搭建本地简易服务器）
简书链接：https://www.jianshu.com/p/ad0833f4845a
2、 做前期准备 导入需要的库文件
1） AFNetworking 和SSZipArchive（一个加载库 一个解压库 ）
podfile：
platform :ios,'8.0'
target 'your project name' do
pod 'AFNetworking'
pod 'SSZipArchive'
end
没有pods 的看这里 cocoapods安装以及使用 https://www.jianshu.com/p/6e71fbeb71b7
3、上代码
1）@property(nonatomic,copy)NSString * urlstr;
@property(nonatomic,copy)NSString * decodestr;
@property(nonatomic,strong)WKWebView * webView;
下载zip代码
-(void)rquestZipArchivePath:(NSString*)pathUrl andHtmlVersion:(NSString*)version{
//远程地址
NSURL*URL = [NSURLURLWithString:pathUrl];
//默认配置
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
//请求
NSURLRequest *request = [NSURLRequest requestWithURL:URL];
NSURLSessionDownloadTask* downloadTask =[managerdownloadTaskWithRequest:requestprogress:^(NSProgress*_NonnulldownloadProgress) {
doublecurr=(double)downloadProgress.completedUnitCount;
doubletotal=(double)downloadProgress.totalUnitCount;
NSLog(@"下载进度==%.2f",curr/total);
}destination:^NSURL*_Nonnull(NSURL*_NonnulltargetPath,NSURLResponse*_Nonnullresponse) {
//- block的返回值, 要求返回一个URL, 返回的这个URL就是文件的位置的路径
NSString *cachesPath = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) lastObject];
//再次之前先删除本地文件夹里面相同的文件夹
NSFileManager*fileManager = [NSFileManagerdefaultManager];
NSArray*contents = [fileManagercontentsOfDirectoryAtPath:cachesPatherror:NULL];
NSEnumerator*e = [contentsobjectEnumerator];
NSString*filename;
NSString*extension =@"zip";
while((filename = [enextObject])) {
if([[filenamepathExtension]isEqualToString:extension]) {
[fileManagerremoveItemAtPath:[cachesPathstringByAppendingPathComponent:filename]error:NULL];
}
}
NSString*path = [cachesPathstringByAppendingPathComponent:response.suggestedFilename];
return[NSURLfileURLWithPath:path];
}completionHandler:^(NSURLResponse*_Nonnullresponse,NSURL*_NullablefilePath,NSError*_Nullableerror) {
//设置下载完成操作
// filePath就是你下载文件的位置，你可以解压，也可以直接拿来使用
NSString*htmlFilePath = [filePathpath];// 将NSURL转成NSString
NSArray*documentArray = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES);
NSString *path = [[documentArray lastObject] stringByAppendingPathComponent:@"Preferences"];
NSFileManager*fileManager = [NSFileManagerdefaultManager];
[fileManagerremoveItemAtPath:[NSString stringWithFormat:@"%@/html",path] error:nil];
self.urlstr=htmlFilePath;
self.decodestr=path;
}];
[downloadTaskresume];
}
解压代码
- (void)releaseZipFilesWithUnzipFileAtPath:(NSString*)zipPath Destination:(NSString*)unzipPath{
// NSLog(@"%@,%@",zipPath,unzipPath);
NSError*error;
if ([SSZipArchive unzipFileAtPath:zipPath toDestination:unzipPath overwrite:YES password:nil error:&error delegate:self]) {
NSLog(@"success");
}
else{
NSLog(@"%@",error);
}
// 压缩包的全路径(包括文件名)
// NSString *destinationPath = zipPath;
// 目标路径,
NSString*destinationPath = unzipPath;
// 解压, 返回值代表是否解压完成
Booleanb= [SSZipArchiveunzipFileAtPath:zipPathtoDestination:destinationPath];
// ------------ 带回调的解压 ------------
Booleanb1 = [SSZipArchiveunzipFileAtPath:zipPathtoDestination:destinationPathprogressHandler:^(NSString*_Nonnullentry,unz_file_infozipInfo,longentryNumber,longtotal) {
// entry : 解压出来的文件名
//entryNumber : 第几个, 从1开始
//total : 总共几个
NSLog(@"progressHandler:%@, entryNumber:%ld, total:%ld names:%@", entry, entryNumber, total,destinationPath);
}completionHandler:^(NSString*_Nonnullpath,BOOLsucceeded,NSError*_Nullableerror) {
//path : 被解压的压缩吧全路径
//succeeded 是否成功
// error 错误信息
NSLog(@"completionHandler:%@, , succeeded:%d, error:%@", path, succeeded, error);
}];
}
#pragma mark - SSZipArchiveDelegate
- (void)zipArchiveWillUnzipArchiveAtPath:(NSString*)path zipInfo:(unz_global_info)zipInfo {
NSLog(@"将要解压%d",zipInfo.number_entry);
}
- (void)zipArchiveDidUnzipArchiveAtPath:(NSString*)path zipInfo:(unz_global_info)zipInfo unzippedPath:(NSString*)unzippedPat uniqueId:(NSString*)uniqueId {
NSLog(@"解压完成！");
}
展示加载zip中的网页
// /初始化一个WKWebViewConfiguration对象
WKWebViewConfiguration *config = [WKWebViewConfiguration new];
//初始化偏好设置属性：preferences
config.preferences = [WKPreferences new];
//The minimum font size in points default is 0;
config.preferences.minimumFontSize = 10;
//是否支持JavaScript
config.preferences.javaScriptEnabled = YES;
//不通过用户交互，是否可以打开窗口
config.preferences.javaScriptCanOpenWindowsAutomatically = YES;
self.webView=[[WKWebView alloc]initWithFrame:self.view.bounds configuration:config];
_webView.navigationDelegate=self;
_webView.UIDelegate = self;
//
NSArray *documentArray = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES);
NSString *path = [[documentArray lastObject] stringByAppendingPathComponent:@"Preferences"];
NSURL *url=[NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/dist/index.html",path]];
NSString*urlStr = [urlabsoluteString];
urlStr = [urlStrstringByReplacingOccurrencesOfString:@"file://" withString:@""];
[self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:urlStr]]];
//uiwebview和wkwebview加载方式略有不同 wkwebview用loadrequest方法不能加载本地html 但是用以上方法可以 应该是后面的 fileURLWithPath起作用了
[self.viewaddSubview:self.webView];
