lua - NSURLErrorDomain error code -999 in iOS -


i've been trying use corona sdk's facebook api post score on game i'm developing on facebook. however, i'm having problem it. during first time try post facebook, error after login , user authentication:

nsurlerrordomain error code -999

then, won't post on facebook. possible causes of error , how can address it? tried searching web couldn't find information it. in advance.

by way, not using webview on app. widget api , show_dialog listener in facebook class.

the error has been documented on mac developer library(ios docs)

the concerned segment documentation be:

url loading system error codes

these values returned error code property of nserror object domain “nsurlerrordomain”.

enum {    nsurlerrorunknown = -1,    nsurlerrorcancelled = -999,    nsurlerrorbadurl = -1000,    nsurlerrortimedout = -1001,

as can see; -999 caused errorcancelled. means: another request made before previous request completed.
