にキーopen_nowの値が欲しいこれは私にNSArrayの出力です。 Not Availableとしていくつかの文字列が含まれており、{"open_now" = 1;で始まるNSDictionaryがいくつか含まれています。 "weekday_text" =（）; }私はopen_nowの値だけを望んでいました。私は私の新しいNSArrayでopen_nowの価値を得る方法を知らない。誰か助けてください。

Answer 1

はい、NSArray -valueForKey：メソッドを使用します。

NSArray *extracted = [sourceArray valueForKey:@"a key"]; 

Answer 2

あなたは、特定のキーの値を取得するためににNSArrayのvalueForKeyPathメソッドを使用することができます。

NSArray *aryValue = [YOUR_ARRAY valueForKeyPath:@"open_now"];
