I've been trying to use Corona SDK's Facebook API to post the score on the game I'm developing on facebook. However, I'm having a problem with it. During the first time I try to post to facebook, I get this error after login and user authentication:
NSURLErrorDomain error code -999
Then, it won't post on facebook. What are possible causes of this error and how can I address it? I tried searching the web but couldn't find information about it. Thanks in advance.
By the way, I am not using webview on my app. Just the widget api and a show_dialog listener in my Facebook class.
The error has been documented on the Mac Developer Library(iOS docs)
The concerned segment from the documentation will be:
URL Loading System Error Codes
These values are returned as the error code property of an NSError object with the domain “NSURLErrorDomain”.
enum { NSURLErrorUnknown = -1, NSURLErrorCancelled = -999, NSURLErrorBadURL = -1000, NSURLErrorTimedOut = -1001,
As you can see; -999
is caused by ErrorCancelled
. This means: another request is made before the previous request is completed.
