This isnt easy. You might want to consider doing this another way. For example you could put the file unzipped on a server and open the link in a webview.

However, if you really want to do it this way there is 2 step.

1. Unzip the file.

You want end up with NSData. Read though some of the links suggested in the comments. You will need to use a 3rd party library to achieve this.

2. Load the data in to a UIWebView.

Write the NSData to the temp directory then point the UIWebView at it.

NSString *path = // .. Get a location in the NSTemporaryDirectory
if ([pptData writeToFile:path atomically:YES]) 
{
    NSURL *url = [NSURL fileURLWithPath:path];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    [webview loadRequest:request]; 
}
