ShareKit SHKFacebookSessionProxyURL

I'm implementing Share开发者_如何学运维Kit in my app. In the SHKConfig.h file, in the section where the Facebook data is inserted, there is a line saying: #define SHKFacebookSessionProxyURL @"".

What am I supposed to enter there?

You can Leave it empty

#define SHKFacebookSessionProxyURL  @""
