このページは[[yoshimasa niwa - iPhoneでOpenCVを使う方法:http://niw.at/articles/2009/03/14/using-opencv-on-iphone/ja]]で紹介されている&br;OpenCV 2.1用のビルドスクリプトをOpenCV 2.2で使うための方法を記載しています．

iOS SDK 4.2で動作させたい場合は[[OpenCV/Using OpenCV 2.2 on iOS SDK 4.2]]を
参照下さい．

**OpenCV 2.2取得 [#p40a0c1f]
[[公式サイト:http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.2/]]からOpenCV-2.2.0.tar.bz2をダウンロードします．

**ビルドスクリプト取得 [#x7ead151]
[[このページ:https://github.com/niw/iphone_opencv_test/commit/4ab0572d48a07f2401a15ca4c894c169983ae0fd]]の「Downloads」ボタンを押して，&br;
niw-iphone_opencv_test-4ab0572.zipをダウンロードします．

**パッチファイル取得 [#kcebe76e]
下記のパッチファイルをダウンロードします．&br;
|Filename|Size|Date|Type|Download|
|BGCOLOR(white):opencv2.2_for_ios_build_script_20101230.zip|BGCOLOR(white):5.06kb|BGCOLOR(white):20101230|BGCOLOR(white):Zip|BGCOLOR(white):[[http://www.atinfinity.info/img/download.gif:http://www.atinfinity.info/opencv/patch/opencv2.2_for_ios_build_script_20101230.zip]]|

このzipに格納されているファイルの内容は以下の通りです．
-OpenCV-2.2.0.patch --- OpenCV 2.2に適用するパッチ
-niw-iphone_opencv_test-4ab0572.patch --- ビルドスクリプトに適用するパッチ

**パッチの適用 [#dcff9e79]
下記の3ファイルを展開します．
-OpenCV-2.2.0.tar.bz2
-niw-iphone_opencv_test-4ab0572.zip
-opencv2.2_for_ios_build_script_20101230.zip

展開後，下記のフォルダを同一階層に配置します．
-OpenCV-2.2.0
-niw-iphone_opencv_test-4ab0572
-opencv2.2_for_ios_build_script_20101230

(1)OpenCV 2.2のディレクトリに移動
 % cd OpenCV-2.2.0

(2)OpenCV 2.2にパッチを適用
 % patch -p1 < ../opencv2.2_for_ios_build_script_20101230/OpenCV-2.2.0.patch

(3)ビルドスクリプトのディレクトリに移動
 % cd ../niw-iphone_opencv_test-4ab0572

(4)ビルドスクリプトにパッチを適用
 % patch -p1 < ../opencv2.2_for_ios_build_script_20101230/niw-iphone_opencv_test-4ab0572.patch

ここまででパッチの適用が完了です．&br;
そして，niw-iphone_opencv_test-4ab0572にある
-opencv_simulator
-opencv_device

ディレクトリ中にあるinclude，lib，shareディレクトリを削除しておきます．&br;
（※OpenCV 2.1用のライブラリとヘッダが格納されているため）
