有两个可能：

一个是没有使用-force_load链接，文档如何链接PaddlePaddle库
一个是没有调用paddle_init函数 https://github.com/PaddlePaddle/Mobile/blob/477186702e368a55c6a3319f2b78257c7c0ac51d/Demo/iOS/AICamera/AICamera/paddle_image_recognizer.h#L71-L71

这两个都没问题，跑普通的cnn模型都ok，就是新用了个带有rnn模型的情况下出现有其他可能原因么？我理解capi应该是完备的支持rnn layer的吧？

哦~想起来了，之前为了最小化paddle库的大小，把recurrent_layer_group相关实现移除了。。。你们对paddle库的大小有要求么？
