The error means that you have connected something to an outlet called date in your nib but that outlet does not exist. Where do you declare date?

data is a label of the custom cell,and I declare it in the TodoTableViewCellController.h – jxdwinter Mar 24 '12 at 14:41
next question, where do you call loadNibNamed? – borrrden Mar 24 '12 at 14:45
It's date, and now I change it'name to dateLabel...and check out the nib file, there is no problem. – jxdwinter Mar 24 '12 at 14:52
I dont understand what "where do you call loadNibNamed" mean? I call this function in the cellForRowAtIndexPath.I change the name ,but same excaption, "for the key date" – jxdwinter Mar 24 '12 at 15:16

OK,I made a mistake : dateLabel connected to the file's owner, it should connect to the CellController! Thank you ! – jxdwinter Mar 24 '12 at 15:31

Set Custom Class of File's Owner to UITableViewCell.
Set Custom Class of cell to your custom table view cell class myCustomCell.
Outlet your UIlabel in myCustomCell.h.

Thanks, this comments saved me! – Joshua Aug 17 '16 at 07:49
This was the answer to my issue. I had set the File's Owner Custom Class to my own class and connected the outlets to that. Thank you. – SagarU Apr 16 '19 at 20:26

Hook up all of your outlets in TododTableViewController XIB (particularly the view outlet), and run again.
