私のデータの構造は、以下のようになる：Objective-C：辞書内の辞書を取得する方法は？

{コース=（{コース{...}、CourseTime（{}、{}）、CoursesStudents（{}、{}）}）}

ここでは詳細に：

私はコース-Dictの取得しようとしている：コース{...}を、私はこれを行う方法を知りません。 私は最初、上側の辞書を取得するコード行を持っていた：

[currentCourse updateDataWithDictionary:responseDict[@"Courses"]];

をしかし、私はサブ辞書を取得する方法がわかりません。私はこれを試した：

[currentCourse updateDataWithDictionary:responseDict[@"Courses"]["@Course"]];

これは動作しません。このサブ辞書を取得する正しい方法は何ですか？

ありがとうございました！

「コース」の内容と「コース時間」は**配列**です。 '（）' - >配列、 '{}' - >辞書です。それは少なくとも 'responseDict [@" Courses "] [0] [@" Course "] [0]' – vadian

答えて

0

これを試してみてください：

NSDictionary *dict = @{ @"key": @{@"subkey": @"value"}}; 
NSLog(@"%@", [dict valueForKeyPath:@"key.subkey"]);

結果：

2016-12-12 14:13:52.478 solution[57:57] value

があなたの場合：

[currentCourse updateDataWithDictionary:[responseDict valueForKeyPath:@"Courses.Course"]];

しかし、辞書のキーCoursesあなたの供給構造では、その正しい方法配列である必要がありますbe：

[currentCourse updateDataWithDictionary:responseDict[@"Courses"][0][@"Course"]];

です。質問のオブジェクトは辞書の辞書ではありません。 – vadian

@vadianはいあなたは正しいです、質問は指定されたデータ構造と一致しません。 –
