Add Files to a ZIP Using AddFile

See more Zip Examples

This example demonstrates how to use the AddFile method to add files from the local filesystem to a ZIP archive.

The example adds two files:

• One file with its relative directory path preserved
• One file stored using only its filename

The AddFile method adds references to local filesystem files. The files are not actually read or compressed until a Write* method is called.

Objective-C

#import <CkoZip.h>

BOOL success = NO;

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

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

//  Add a file and preserve its relative directory structure
//  within the ZIP archive.
//  
//  The following file:
//      c:/projects/app/docs/readme.txt
//  
//  Will be stored in the ZIP as:
//      projects/app/docs/readme.txt
//  
BOOL saveExtraPath = YES;
success = [zip AddFile: @"c:/projects/app/docs/readme.txt" saveExtraPath: saveExtraPath];
if (success == NO) {
    NSLog(@"%@",zip.LastErrorText);
    return;
}

//  Add a file using only the filename in the ZIP archive.
//  
//  The following file:
//      c:/temp/logo.png
//  
//  Will be stored in the ZIP as:
//      logo.png
//  
saveExtraPath = NO;
success = [zip AddFile: @"c:/temp/logo.png" saveExtraPath: saveExtraPath];
if (success == NO) {
    NSLog(@"%@",zip.LastErrorText);
    return;
}

//  Write the ZIP archive to disk and close it.
//  The source files are consumed at this time.
success = [zip WriteZipAndClose];
if (success == NO) {
    NSLog(@"%@",zip.LastErrorText);
    return;
}

NSLog(@"%@",@"ZIP archive created successfully.");
