Xcode 6.2 以上
https://developer.apple.com/xcode/downloads/
6.2からAppleWatch開発環境(watchkit)が入っています。

iOS8.2以上 (iPhone)
8.2にバージョンアップするとアプリ「Apple Watch」が追加されるのですぐわかります。

AppleWatch ->WatchKit Appを選択します。

Interface.storyboardでUIを作成します。
Apply Map位置ボタン、Tokyou Map位置ボタン、拡大縮小ボタン、ピンボタン、画像ボタン、画像消去ボタン等
下記の通りGroupを使いボタンとMapを貼り付けます。
Mapは画面いっぱいに表示したいのでwidthもheightもRelative to Containerにします。

Mapのソースコード
InterfaceController.mに記述します。

#import "InterfaceController.h"

@property (nonatomic) MKCoordinateRegion currentRegion;
