Questions about live2D sample code(ios) - compile error / live2d draw anything

First, I'm sorry not to use japanese.

I tried to run sample code of live2D and tutorial code I made. I had problems in both two projects.

1. In sample code..

Live2DSDK : Live2D_SDK_OpenGL_2.zip / sample / simple / proj.ios
開発環境 : MacOS Sierra 10.12.4, Xcode 8.3
エラー内容 : After running project, console prints below texts. (when live2DModel->draw(); is called)
エラーログ : Below texts. haru does not drawn.
備考 : iPhone7
関連するコード : I just run sample code. (*When I allocate EAGLcontext, using api 'kEAGLRenderingAPIOpenGLES2' generate below error. But using api 'kEAGLRenderingAPIOpenGLES1' didn't generate below error( but draw anything). I want to know why it works like this).

Live2D version 2.1.05 for iPhone ES2

2. I made my own project using tutorial guide. (http://sites.cybernoids.jp/cubism2_kr/sdk_tutorial/platform-setting/ios/createproject)


Live2DSDK : Live2D_SDK_OpenGL_2
開発環境 : MacOS Sierra 10.12.4, Xcode 8.3
エラー内容 : "live2DModel->draw();" draws nothing. I checked openGL function and found every render function works well.
エラーログ : Nothing printed after "Live2D version 2.1.05 for iPhone ES2" in console.
備考 : iPhone7
関連するコード : I follow just the tutorial. Is there anything I should set before running project?


I want to use live2D to ios using openGL quickly but take your time. I look forward your opinions.
