Append Part to MIME

See more MIME Examples

Demonstrates the AppendPart method for adding sub-parts to MIME. 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.

    // Create a text/plain part.
    let ptMime = CkoMime()!
    ptMime.setBody(fromPlainText: "This is the plain text body")
    print("\(ptMime.getMime()!)")
    print("****")

    // The ptMime contains:
    // ---------------------------------------
    // 	Content-Type: text/plain
    // 	Content-Transfer-Encoding: 7bit
    // 
    // 	This is the plain text body
    // ---------------------------------------

    // Start with an empty MIME object...
    let topLevelMime = CkoMime()!

    // Initialize it to a multipart Content-Type.  We'll use multipart/mixed.
    topLevelMime.newMultipartMixed()

    // Append the ptMime as a child.
    topLevelMime.appendPart(mime: ptMime)
    print("\(topLevelMime.getMime()!)")
    print("****")

    // The topLevelMime contains:
    // --------------------------
    // 	Content-Type: multipart/mixed; boundary="------------010907090104040508040404"
    // 
    // 	--------------010907090104040508040404
    // 	Content-Type: text/plain
    // 	Content-Transfer-Encoding: 7bit
    // 
    // 	This is the plain text body
    // 	--------------010907090104040508040404--
    // 

    // IMPORTANT: A copy of the MIME passed in AppendPart is appended.
    // Therefore, in this case, changing ptMime does not change the text/plain sub-part in topLevelMime.
    // For example:
    ptMime.setBody(str: "this is the new plain text body.")
    // topLevelMime is unchanged.
    print("\(topLevelMime.getMime()!)")
    print("****")

    // To change the content in topLevelMime, we must get the text/plain part.
    // For example:

    let ptMime2 = CkoMime()!
    topLevelMime.part(at: 0, subPart: ptMime2)

    ptMime2.setBody(str: "this is the new plain text body.")
    // Now topLevelMime is changed.
    print("\(topLevelMime.getMime()!)")
