ドキュメントを書くとき、ObjCの setTile:forState: を Swfitでどう書くか。

setTitle(_: String!, forState: UIControlState)

フルパターン。

メリット:

• 情報量が多くてわかりやすい
• オーバーロードしていても曖昧でない

iOSでもOpenCLを使えるか調べてみた

いつまで経ってもPrivate Frameworksに引き蘢っているiOSのOpenCL APIは果たして本当に使えるのか？ というわけでアプリから引き摺り出してみます。Jailbreakはしません。

とりあえずdlopen(3)してみる

Private Frameworksは基本的にSDK配下のものと同じパスでランタイムにdlopen(3)する事が出来るので、実機で開いてみます。
