Passing via segue, PFObject crash Parse.com - ios

Question

I am lost with segue. I tried to do it through this tutorial.
Everything is working but only one line write me error and I don`t know how to fix it.
Image with error:

Answer 1

From what I read from your code it is because you are using a normal UITableViewController. To be able to access the property "self.objects" you have to be using Parse's subclassed UITableViewController called "PFTableViewController". They have included the property "objects".
I can recommend this tutorial to get an understanding of the PFTableViewController
http://www.appcoda.com/ios-programming-app-backend-parse/
If you want it to work without the PFTableView you can do the following:
I can see that you have an array called colorsArray and that you add the Parse objects into that array.
So instead of doing this:
PFObject *object = [self.objects objectAtIndex:indexPath.row];
You can do this:
PFObject *object = [colorsArray objectAtIndex:indexPath.row];
I hope it works out for you!

Answer 2

Along with doing the tutorial which another answer here has suggested, perhaps you ought not to pass the PFObject itself...
Figure out and query whatever text you are trying to show in your detail view controller, retrieve it in the table view controller, then ONLY pass that (instead of a entire PFObject).
