See this answer for decompressing the zip file (it uses an external library for decompression). Use UIWebView to display the HTML.

Use ZipArchive to Unzip your files at some path

- (void)unzipFileAt:(NSString *)sourcePath toPath:(NSString *)destnPath{
    ZipArchive *zipper = [[ZipArchive alloc]init];
    if ([zipper UnzipOpenFile:sourcePath]) {
        [zipper UnzipFileTo:destnPath overWrite:YES];
        [zipper UnzipCloseFile];

    }
}

Construct your path for index.html file like this,

NSString *filePath = [NSString stringWithFormat:@"%@/index.html",yourPathWhereTheFileWasUnzipped,pathComponent];

Load your UIWebView with the path variable.

self.html5View.scalesPageToFit = NO;
[self.html5View  loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:filePath]]];

This works like a charm for me, for loading HTML5 files.

First you have to download the zip file from the server using library like ASIHTTP Then you have to unzip the zipped file using SSZipArchive to a specific folder in your Document folder Now just load a UIWebView with the NSURL made from the path of the index.html file inside the unzipped folder.
