私は iOS 開発が初めてで、2 つの を比較するのに苦労していNSMutableArray
ます。
それらの 1 つ ( コード内 ) にappDelegate.array
はデータベースからのデータが含まれ、もう 1 つ (dataArray
コード内 ) にはサーバー応答からのデータが含まれます。
dataArray
ここで、( ) の各要素を ( ) 全体と比較し、( )appDelegate.array
の要素が ( dataArray
) に存在するappDelegate.array
場合は何もしないか中断し、存在しない場合はデータベースに追加します。
試しましたが、これを行うことができません。以下は私が使用しているコードです。
前もって感謝します。
