Issue while implement the jpush in unity for ios version

Hi.
I’m unity developer & first in jpush.
I implemented jpush in unity for ios version & followed the guide for unity integration.
“Not get deviceToken yet. Maybe: your certificate not configured APNs? or current network is not so good so APNs registration failed? or there is no APNs register code? Please refer to JPush docs.”
But when I ran the game in the iphone, I got this issue.
Could you help me?
