これは私が使用しているものです:

それを使用するには、インポートRequestPerformer.h
してUIViewController
次のようにします。
[requestManager performGetRequestWithString:tempString stringDictionary:stringDictionary dataDictionary:dataDictionary delegate:self requestSelector:@selector(requestSucceeded:) errorSelector:@selector(requestFailed:)];
パラメーター:
(NSString *)string
- URL 文字列、リクエストを投稿する場所。
(NSDictionary *)stringDictionary
- すべてのテキスト情報 (名前、ID など) を含む辞書。
(NSDictionary *)dataDictionary
- すべてのデータ情報 (写真、ファイルなど) を含む辞書。
(id)requestDelegate
- 以下のセレクターの実行を委譲します。
(SEL)requestSelector
- リクエストが成功している間に実行されるセレクター。
(SEL)errorSelector
- エラーが発生したときに実行されるセレクター。
