8の1つ目：どのように注目を集めたか

こんばんは、はらちたててり！



8+ in 1：iOSおよびAndroidの新しいメッセンジャーがリリースされる前に、プレスリリースを公開する場所を調査するためにいくつかの作業を行う必要がありました。 そのような場所の1つはHabrでした。



次の質問をしました。





画像







エントリー


最初から、私はどこかで似たような記事を見たような気がしました。 見つけることができなかった、おそらく私は見た目が悪かったので （ ここ 、 ここ 、 ここ ）、調査自体を実施し、可能であれば興味深い点を見つけることにしました。



「ベスト」とは、閲覧（読み取り）、ブックマークへの追加、または投稿へのコメントを行うユーザーの最大数を集めることを意味します。



すべては記事の解析から始まりました。 幸いなことに、Habrには、安全に歩いて情報を収集できる投稿識別子があります。

急いで、グラバーはObjective-Cで書かれました。

フィルタリング


今、あなたはすべての余分なファイルを取り除く必要があります-これらは隠された投稿があるページまたはまだ作成されていないページです。

並行して、各ページを処理し、必要なデータを「切り取り」、別のファイル（共有）に書き込むことができます。



各ブログエントリから、次の情報を受け取ります。
