UIScrollView's visible region are overlapping on simulator

cocos2d-x JavaScript
#1

i created an uiscrollview and set the size of it.it worked well on Chrome/Firefox,but when i ran the project on simulator through jsb, the uiscrollview showed content outside theirs size.then i created another uiscrollview through cocostudio v1.1.0 and the result was same.i think maybe there r some mistakes on JSB?

#2

solved:

in AppController replace the gl-view creation with:

EAGLView *__glView = […
depthFormat: GL_DEPTH24_STENCIL8_OES
…];
