问题
I want to post the several same messages onto my feed/wall in an iOS application.
From the 2nd try, I receive this error -
(#506) Duplicate status message.
How can I solve it?
回答1:
You can't.
That is Facebook's way to tell you to stop spamming.
Sorry if it sounds slightly mean - but posting the same message over and over and over again is spamming, and its not good. The error message you are getting describes the problem - you are posting the same status message. It is a special error message created specifically for this case.
回答2:
I check for the 506 code and don't show any error to the user in case it's a duplicate status error
if (error && [[[[[error.userInfo objectForKey:@"com.facebook.sdk:ParsedJSONResponseKey"] objectForKey:@"body"]objectForKey:@"error"]objectForKey:@"code"] intValue] !=506) {
alertTitle = NSLocalizedString( @"SomethingWentWrongTitle", nil);
}
