How to open a zip and modify the filename of one or more files within the zip before unzipping. Objective-C

#import <CkoZip.h>
#import <CkoZipEntry.h>

BOOL success = NO;

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

CkoZip *zip = [[CkoZip alloc] init];

success = [zip OpenZip: @"test.zip"];
if (success == NO) {
    NSLog(@"%@",zip.LastErrorText);
    return;
}

CkoZipEntry *entry = [[CkoZipEntry alloc] init];

success = [zip EntryOf: @"hamlet.xml" entry: entry];
if (success == NO) {
    NSLog(@"%@",zip.LastErrorText);
    return;
}

entry.FileName = @"hamlet2.xml";

success = [zip EntryOf: @"helloWorld.pl" entry: entry];
if (success == NO) {
    NSLog(@"%@",zip.LastErrorText);
    return;
}

entry.FileName = @"hw.pl";

// Now unzip to the "test" subdirectory, under our current
// working directory:
int numFilesUnzipped = [[zip Unzip: @"test"] intValue];
if (numFilesUnzipped < 0) {
    NSLog(@"%@",zip.LastErrorText);
    return;
}

// The filenames within the .zip are unchanged, but it unzipped
// test/hw.pl and test/hamlet2.xm
