Bump Api送信に関するヘルプが必要です

Question

私はここで何か助けが必要です。バンプを使って、あるiPhoneから別のiPhoneにJpgまたはPNG画像を転送したいと思います。私はイメージが全く送られない成功と失敗に遭遇しました。

は、ユーザーがUIimagepickerから画像を選択したときに呼び出されるNSObjectファイルです。

受信者はデータを送信せずに受信します。

私はコードを見て、私に任意のコメントやポイントを与えるのを助けてください。

ありがとうございました。

Answer 1

私は、Bumpを使用して256kの制限を超えて画像やその他のデータを転送するのが非常に遅いことを発見しました。ペイロードをチャンクにバストアップさせなければならず、各チャンクが送受信されるまでに遅延があります。あなたがあなた自身のウェブサーバーを持っている場合は、ここで私はどうなるのかです：

1. アプリをお持ちのあなたのウェブサーバーに画像をアップロードするWebサービス
2. のいくつかの並べ替えを経由してWebサービスを持っているIDやパスを返しますアップロードされたファイルせいぜい
3. アプリの受信機部分は、Webサーバから画像を取得した唯一の数kは OVER INFORMATION
4. BUMP

あなたはあなたの移籍がどれほど速くなるかに驚くでしょう！
