Step one - create screenshot: How to take a screenshot programmatically

Second - save it: How to save UIImage to file with NSFileManager?

Third - zip it. You can use zlib wrapper objective-zip

EDITED: here is some code from objective-zip embedded sample:

    ZipFile *zipFile= [[ZipFile alloc] initWithFileName:filePath mode:ZipFileModeCreate];
    [self performSelectorOnMainThread:@selector(log:) withObject:@"Adding first file..." waitUntilDone:YES];
    ZipWriteStream *stream1= [zipFile writeFileInZipWithName:@"abc.txt" fileDate:[NSDate dateWithTimeIntervalSinceNow:-86400.0] compressionLevel:ZipCompressionLevelBest];
    [self performSelectorOnMainThread:@selector(log:) withObject:@"Writing to first file's stream..." waitUntilDone:YES];
    NSString *text= @"abc";
    [stream1 writeData:[text dataUsingEncoding:NSUTF8StringEncoding]];
    [self performSelectorOnMainThread:@selector(log:) withObject:@"Closing first file's stream..." waitUntilDone:YES];
    [stream1 finishedWriting];

    [self performSelectorOnMainThread:@selector(log:) withObject:@"Adding second file..." waitUntilDone:YES];

    ZipWriteStream *stream2= [zipFile writeFileInZipWithName:@"x/y/z/xyz.txt" compressionLevel:ZipCompressionLevelNone];

    [self performSelectorOnMainThread:@selector(log:) withObject:@"Writing to second file's stream..." waitUntilDone:YES];
    NSString *text2= @"XYZ";
    [stream2 writeData:[text2 dataUsingEncoding:NSUTF8StringEncoding]];

    [self performSelectorOnMainThread:@selector(log:) withObject:@"Closing second file's stream..." waitUntilDone:YES];
    [stream2 finishedWriting];
    [self performSelectorOnMainThread:@selector(log:) withObject:@"Closing zip file..." waitUntilDone:YES];

    [zipFile close];
    [zipFile release];
