runAnimationsForSequenceNamed is nil

Cocos2d-x
#1

版本2.2.1

local animationManager = layer:getUserObject()
animationManager:runAnimationsForSequenceNamed(name)

这段代码在android上运行正常，但是在ios上不嫩运行，下面是log：

Cocos2d:  :231: attempt to call method 'runAnimationsForSequenceNamed' (a nil value)

哪位大神知道这怎么解决？
