iOS開発のド初心者ながら、romo SDKで開発しようとしてsdkのサンプルプロジェクトをビルドしようとしたらエラーになったのでメモ。
環境
- OS X 10.9
- Xcode6.0
- RomoSDK1.0
エラー内容
色々調べたけど分からんかった。

- 知人曰く、arm64 x86_64とかエラーが出てたのでiPhone5まで32bitOSでiPhone5sからが64bitOSな設計になってるとかなんとか...
build targetをiPhone5以前のものにするとエラー解消しました。
iPhone5sや6でもbuildする方法
- Build Settings -> Architectures -> ArchitecturesでOtherを選択
$(ARCHS_STANDARD)って書いてあると思うのですが、その項目を削除してarmv7と入力しましょう。
Architecruersがarmv7の状態でbuildするとiPhone5s(ちなみにiOS8)でも動きました!
よっしゃ!
