iOS FacebookSDK Video Upload - ios

Question

I am trying to upload a video from my iOS app to Facebook and I am using the code:
NSString *filePath = [[NSBundle mainBundle] pathForResource:#"sample" ofType:#"mp4"];
NSData *videoData = [NSData dataWithContentsOfFile:filePath];
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
videoData, #"video.mp4",
#"video/mp4", #"contentType",
#"Video Test Title", #"title",
#"Video Test Description", #"description",
nil];
[FBRequestConnection startWithGraphPath:#"me/videos"
completionHandler:^(FBRequestConnection *connection,
id result, NSError *error)
{
[FBRequestConnection startWithGraphPath:#"me/videos"
parameters:params
HTTPMethod:#"POST"
completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
if(!error)
{
NSLog(#"SUCCESS RESULT: %#", result);
}
else
{
NSLog(#"ERROR: %#", error.localizedDescription);
}
}];
But I am getting the error:
FBSDKLog: Error for request to endpoint 'me/videos': An open FBSession must be specified for calls to this endpoint.
ERROR: The operation couldn’t be completed. (com.facebook.sdk error 5.)
Can any one please help me?

Answer 1

Log the access token to see if you have a valid one:
NSLog(#"AccessToken:%# ",FBSession.activeSession.accessTokenData.accessToken);
You need to be logged into your app via Facebook and need to have the publish_actions permission granted before you can make a POST request of any sort.
Once you have the access token, to quickly verify if it is valid and has the appropriate permissions, use the access token debugger.
