I solved my problem with #import and now i encountered another problem.
So i need my app to have PFQueryTableViewController. Now.
Storyboard:
I have mainmenuViewController with several buttons. I wanted one to send me to UITableViewController. So i just link(ctrl+drag) button on mainmenuViewController to new UITableViewController. Everything works fine and push occurs.
Now when i subclass UITableViewController to my new file(subclass PFQueryTableViewController) my app suddenly throws SIGABRT whenever i click on linked button.
I have no idea why it happens. I watched several tutorial videos and it seems like people there don't do anything more than just - create UITableViewController, subclass it to PFQueryTableViewController and link button from another view to UITableViewController.
However when i follow these steps SIGABRT comes up and crashes my app.
Any idea what is happening?
Alright guys i think i finally fixed this. Well as most would say - there is nothing worse than being lazy in coding. I was too lazy to read whole documentation of Parse and there ya go. I beg you for forgiveness.
For anyone having this problem : read https://parse.com/docs/ios/guide#objects-subclasses PFQueryTableViewController section.
Parse has awesome documentation - better than most frameworks.
From now on i say NO to laziness!
