Create Zip in a BinData Object

See more Zip Examples

Recursively appends files in a directory tree and writes a zip archive into a Chilkat BinData object. Swift

func chilkatTest() {
    var success: Bool = false

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

    let zip = CkoZip()!

    // Initialize the zip object.  Because we will never actually write a zip file to the filesystem,
    // the filepath passed to NewZip does not matter.
    success = zip.newZip(zipPath: "x.zip")
    if success != true {
        print("\(zip.lastErrorText!)")
        return
    }

    // Append a directory tree.  The call to 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 WriteBd, WriteZip, or WriteZipAndClose 
    // is called, the referenced files are streamed and compressed
    // into the .zip output file (or BinData object).

    var recurse: Bool = true
    success = zip.appendFiles(filePattern: "c:/temp/a/*", recurse: recurse)
    if success != true {
        print("\(zip.lastErrorText!)")
        return
    }

    // Write the zip archive into the bdZip object.
    let bdZip = CkoBinData()!
    success = zip.writeBd(binData: bdZip)
    if success != true {
        print("\(zip.lastErrorText!)")
        return
    }

    // We could directly access the bytes of the zip archive, or perhaps
    // get the zip bytes in base64 format.
    var zipAsBase64: String? = bdZip.getEncoded(encoding: "base64")
    print("\(zipAsBase64!)")

    // Or the zip can be used by some other Chilkat method call that accepts
    // a BinData object as an argument.
