前提・実現したいこと
※初心者です
jsonデータ(items)を画面遷移で渡したいです。
それにともなってやりたいことは以下の通りです。
①メンバ変数に定義(配列のデータを配列に格納したい)
②JSONデータの受け渡し(tableviewのTapした箇所)
Googleと検索した際にforの中で「items」をループで取り出しています。
「hosts」「googletest」など順にtableに出力されます。
tableで「hosts」をタップした時に「hosts内の情報」、「googletest」をタップした時に「googeltest」内の情報」を順番に出したいです。
※ JSONデータ https://api.github.com/search/repositories?q=%20Google
(配列の中に連想配列があります)
下記、JSON + searchBar.text!からの値になります。
