Unzip Files to Byte Array

See more Zip Examples

Demonstrates how to unzip each file contained in a .zip to an in-memory byte array. Objective-C

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

BOOL success = NO;

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

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

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

// Iterate of each entry in the zip.
// An entry can be a file or directory entry.  For each file, unzip to a byte array.
int numEntries = [zip.NumEntries intValue];
NSLog(@"%@%d",@"NumEntries = ",numEntries);

CkoZipEntry *entry = [[CkoZipEntry alloc] init];
int i = 0;
while (i < numEntries) {
    [zip EntryAt: [NSNumber numberWithInt: i] entry: entry];
    if (entry.IsDirectory == NO) {
        NSData fileData = [entry Inflate];
        // Do whatever you wish with the file data...
    }

    i = i + 1;
}

[zip CloseZip];

NSLog(@"%@",@"Finished.");
