这是我的NSArray的输出。它包含一些不可用的字符串，它包含一些以{“open_now”= 1开头的NSDictionary; “weekday_text”=（）;我只想要open_now的值。我不知道如何在我的新NSArray中获得open_now的值。请有人帮助我。

Answer 1

是的，使用NSArray -valueForKey：方法。

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

Answer 2

您可以使用 NSArray 的 valueForKeyPath 方法获取特定密钥的值。

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

我想要数组中的键open_now的值
