私は何かおかしなことに悩まされています。以前ASIHTTPRequestはWebサービスからデータを受信していましたが、すべて正常に機能していました。を使用するように切り替えましたがNSURLConnection、同じデータを受け取り、同じ方法で解析していますが、コードが。を使用してデータを認識しませんNSURLConnection。
これが私が受け取っているデータです（からNSLog）
Did receive data: {"d":"[{\"id\":1.0,\"Category\":1,\"hPlan\":0.0,\"Tip\":\"It takes 3500
calories to gain a pound. If you want to lose a pound per week, reduce your calorie
intake by 250 calories and incorporate daily physical activity that will burn 250
calories.\",\"TipDate\":\"2012-05-12T00:00:00\",\"TimeStamp\":\"AAAAAAAAB9I=\"}]"}
