NSDataとNSStringの相互変換

Posted at

ググればすぐ出てくるけどよく忘れるのでメモ。
カテゴリとして実装し、asDataasUTF8Stringなどを生やして使うのが楽かも知れない。

NSData to NSString

NSString *string = [[NSString alloc] initWithData:data 
                                         encoding:NSUTF8StringEncoding];

NSString to NSData

NSData *data = [string dataUsingEncoding:NSUTF8StringEncoding];
