I found interesting issue.
When i'm requesting new publish permissions, fb sdk shows dialog with the "Skip" button. I'm handling it like this
[[[appDelegate facebook] session] requestNewPublishPermissions:permissions
defaultAudience:FBSessionDefaultAudienceEveryone
completionHandler:^(FBSession *session, NSError *error)
{
if (!error)
{
//do smth if there is no error
}
}];
But when user pressed "Skip" inside the dialog - error is nil.
How to handle it? Maybe i don't understand smth. Thx.
same for me, seems like this is bug in Facebook SDK, but I am not sure. I have added additional check if session has new permissions.
- (void)postToFacebookWithMessage:(NSString *)message completionBlock:(void (^)(NSError *))completionBlock
{
NSArray *permissions = @[@"publish_actions"];
void (^completionHandler)(FBSession *session, NSError *error) = ^(FBSession *session, NSError *error) {
if (error != nil)
{
if (completionBlock != nil)
{
completionBlock(error);
}
}
else if(![self activeSessionHasPermissions:permissions])
{
NSError *error = [NSError errorWithDomain:@"Facebook" code:FBAccessDisabledCode userInfo:@{NSLocalizedDescriptionKey:NSLocalizedString(@"Facebook access disabled", @"Facebook access disabled")}];
if (completionBlock != nil)
{
completionBlock(error);
}
}
else
{
NSMutableDictionary<FBGraphObject> *action = [FBGraphObject graphObject];
action[@"message"] = message;
[FBRequestConnection startForPostWithGraphPath:@"me/og.posts" graphObject:action completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
// internal error 1611231 means that this was already posted
if (error.code == 5)
{
error = [NSError errorWithDomain:@"Facebook" code:FBDuplicateActionErrorCode userInfo:@{NSLocalizedDescriptionKey:NSLocalizedString(@"Already posted to Facebook", @"Already posted to Facebook")}];
}
if (completionBlock != nil)
{
completionBlock(error);
}
}];
}
};
if ([self activeSessionHasPermissions:permissions])
{
completionHandler([FBSession activeSession], nil);
}
else
{
[[FBSession activeSession] requestNewPublishPermissions:permissions defaultAudience:FBSessionDefaultAudienceEveryone completionHandler:completionHandler];
}
}
- (BOOL)activeSessionHasPermissions:(NSArray *)permissions
{
__block BOOL hasPermissions = YES;
for (NSString *permission in permissions)
{
NSInteger index = [[FBSession activeSession].permissions indexOfObjectPassingTest:^BOOL(id obj, NSUInteger idx, BOOL *stop) {
if ([obj isEqualToString:permission])
{
*stop = YES;
}
return *stop;
}];
if (index == NSNotFound)
{
hasPermissions = NO;
}
}
return hasPermissions;
}
hope this will help
