Objective-C Webページと同様のPOST送信をする
概要
業務報告アプリのサーバー側（受け取り側）の処理を書いている時にクライアント（iPhone）から送られてくるデータの構造が項目を\f（改ページ）で区切られたものだった。サーバー側で配列N番は〇〇という処理が書かれていたがそれを修正する気が置きなかったので、iPhoneのデータ送信部分を作り直し時に書いたクラス。
もしかしたら誰かの役に立つかもしれない。当時の自分のように。
jsonでよかったのでは?
- 通常のWebページからのデータ受信処理が既に出来ていた
- 画像や音声データがたまに壊れて送られてたので作り直す必要はあった
処理
- Webページのformからポストした時と同じ形式でデータを送信する
- 画像や音声データも送信可能
- 非同期ではない
GitHub
ソースコードそのまま
2013年製でガベージコレクションもOFFの状態で書いたものなのでコードが古臭い
プロパティに「self->」と付けているのは自分は絶対にthisやmeを付ける派（当時は頑固）だった
PHPで書いたPHP Webページと同様のPOST送信をする - Writing in an Appropriate Styleと比較すると完成度とエレガントさが足りない
治したい…誰も使わんやろし自分使う予定ないしめんどくさい…
