JSB doesn't support cc.Loader.purgeCachedData & cc.Loader.getInstance().getPercentage()?

JSB doesn’t support cc.Loader.purgeCachedData & cc.Loader.getInstance().getPercentage()?
i am not sure do i need them on mobile device or not? they work very well on HTML5 version.
also upgrade to Cocos2DHTML5 2.2.1 sprite.setFlipX has change to sprite.setFlippedX, but JSB still require sprite.setFlipX.

above test under Cocos2DX 2.2.0 & 2.2.1

Yes, jsb doesn’t support these two functions.
And they’re not needed in jsb.
The function setFlippedX has been added to jsb in v3.0alpha1.
