Swift

Iterate over Matching Filenames

See more Zip Examples

Iterates over files within a .zip that match a pattern. In this case, the pattern is "*.pem". This example will open a .zip containing files of type .txt, .cer, .pem, and possibly others, and will iterate over only the .pem files. Swift

func chilkatTest() {
    var success: Bool = false

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

    let zip = CkoZip()!

    // Open a .zip containing PEM files, among other things..
    success = zip.open(zipPath: "qa_data/certs/thawte-roots.zip")
    if success == false {
        print("\(zip.lastErrorText!)")
        return
    }

    let entry = CkoZipEntry()!
    var pemStr: String?
    var pattern: String? = "*.pem"

    var bHasMoreMatches: Bool = zip.entry(matching: pattern, entry: entry)
    while bHasMoreMatches == true {

        print("Entry: \(entry.fileName!)")

        // Get the uncommpressed contents of the entry:
        pemStr = entry.unzip(toString: 0, srcCharset: "utf-8")
        print("\(pemStr!)")

        bHasMoreMatches = entry.getNextMatch(pattern: pattern)
    }
