ios - AFNetworking 2.0 parsed data not displaying in table view -

my issue: no data displaying in table.

below code being used retrieve json object array , parse using afnetworking 2.0. have uiviewcontroller placed tableview prototype cell has reuse identifier eventcell. want display title , image in every cell. no errors @ runtime.

below nslog output when run project on simulator (note not of nslog statements displaying).

i can't catch issue is, app builds , runs on simulator, cells appear empty. appreciate help. thanks, jt.

possible sources of problem include:

• failure connect iboutlet table view. if tableview property not hooked properly, nil, , [self.tableview reloaddata] nothing (because sending message nil object nothing).

  frankly, i'm unclear how tableview property getting set, because lacks typical iboutlet qualification used when connecting controls in interface builder , don't see setting programmatically, either.

• failure specify view controller delegate and, more importantly, datasource of table view. if case, if called [self.tableview reloaddata], not result in uitableviewdatasource methods being called).

i'd suggest checking self.tableview , self.tableview.datasource non-nil.
