How to create a .zip archive excluding (skipping) files that match a set of wildcarded patterns. Objective-C

#import <CkoZip.h>
#import <CkoStringArray.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 NewZip: @"test.zip"];
if (success != YES) {
    NSLog(@"%@",zip.LastErrorText);
    return;
}

// Create a string array object with our set of filename patterns
// to be excluded:
CkoStringArray *sa = [[CkoStringArray alloc] init];
success = [sa Append: @"*.bak"];
success = [sa Append: @"*.tmp"];

// Tell the zip object to use these exclusions:
[zip SetExclusions: sa];

// Append a directory tree.  The AppendFiles does
// not read the file contents or append them to the zip
// object in memory.  It simply appends references
// to the files so that when WriteZip (or WriteZipAndClose,
// or WriteExe, etc.) is called, the files are compressed
// and encrypted.
BOOL recurse = YES;
success = [zip AppendFiles: @"/temp/a/*" recurse: recurse];

success = [zip WriteZipAndClose];
if (success != YES) {
    NSLog(@"%@",zip.LastErrorText);
    return;
}

NSLog(@"%@",@"Zip Created!");
