私の質問: Android と iOS の両方で XMPP 経由で Spark クライアント (Spark 2.6.3) にファイル転送を行っています。Android ではこれを成功させましたが (ライブラリが優れているため)、iOS ではまだ成功していません。ただし、両方のデバイスで、バイトストリームを介した転送が失敗することに気付きました...
<error code="404" type="CANCEL"><item-not-found xmlns="urn:ietf:params:xml:ns:xmpp-stanzas"/><text xmlns="urn:ietf:params:xml:ns:xmpp-stanzas" xml:lang="en">Could not establish socket with any provided host</text></error>
Android では、転送は ibb ... に頼ることで完了します。
<iq id="DK1IO-19" to="myUsername@beta.myCompany.co.uk/Spark 2.6.3" type="set"><open xmlns="http://jabber.org/protocol/ibb" block-size="4096" sid="jsi_4740809287923906297" stanza="iq"/></iq>
また、Android では、Spark から Android アプリにファイルを送信すると、バイトストリーム経由で正常に動作するようです。
iOS では、ibb 接続を自分でコーディングする必要がありますが、そもそもバイトストリームが失敗するのはなぜでしょうか?

非プロキシ ストリームホストが使用されている場合、Spark から iOS アプリに送信しようとすると、接続が拒否されることに注意してください。(このSOCKS プロトコル バージョン 5ドキュメントのポイント 6 のように)。次のコードでは Rep は 5 です (ただし、0 である必要があります)。
UInt8 ver = [NSNumber extractUInt8FromData:data atOffset:0];
UInt8 rep = [NSNumber extractUInt8FromData:data atOffset:1];
