iOSApiを使っていると、NSStringからStringに変換する必要がでる
そんな時、便利な関数がデモフォルダの Apple.Utils 中に含まれていた
これから、なにかとお世話になりそうなので、メモっておきます

　NSStringToString(AStr: NSString): string

■iOSApiの種類

iOSApi.Foundation,　//Macの一番基本になる部分　NSクラスはこの中に入っている
iOSApi.UIKit,　 //ユーザインターフェース関連の基本的クラスが含まれている
iOSApi.QuartzCore,　//？
iOSApi.CocoaTypes　 //？

■Apple.Utilsの格納場所

(デモフォルダ)\Delphi\RTL\CrossPlatform Utils\Apple.Utils.pas
