iOS SDK Examples do not work

[zch...@ncsu.edu]

Hi,

I am a beginner of 7digital. I apologize in advance if my question is stupid.

I have downloaded the examples from github. However,  it shows nothing like this when I run it (after logging in):

I guess that is because the refreshLocker function in LockerTableViewController.m does not work properly. So the sdRelease variable is empty. 

Any suggestions about how to fix this issue?

Thanks,

Zeyuan
