Add Binary Data to a ZIP Using AddBd

See more Zip Examples

This example demonstrates how to use the AddBd method to add binary data from a BinData object as a file entry within a ZIP archive.

The data is created entirely in memory, added to the ZIP as data/binary.dat, and then written to disk.

Objective-C

#import <CkoZip.h>
#import <CkoBinData.h>

BOOL success = NO;

//  Create a new ZIP archive.
CkoZip *zip = [[CkoZip alloc] init];

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

//  Create a BinData object containing binary content.
CkoBinData *bd = [[CkoBinData alloc] init];

//  Append some bytes as hexadecimal.
//  The decoded bytes will become the contents of the ZIP entry.
success = [bd AppendEncoded: @"000102030405060708090A0B0C0D0E0F" encoding: @"hex"];
if (success == NO) {
    NSLog(@"%@",bd.LastErrorText);
    return;
}

//  Add the BinData contents as a file entry within the ZIP.
//  The file will be stored as "data/binary.dat" inside the ZIP archive.
success = [zip AddBd: @"data/binary.dat" bd: bd];
if (success == NO) {
    NSLog(@"%@",zip.LastErrorText);
    return;
}

//  Write the ZIP archive to disk and close it.
success = [zip WriteZipAndClose];
if (success == NO) {
    NSLog(@"%@",zip.LastErrorText);
    return;
}

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