UITableView crash gives 'CALayerInvalidGeometry', reason: 'CALayer position contains NaN: [160 nan]'

Question

I have a custom table view in my app. I have implemented the \"Load More\" feature to the table which loads 25 rows at a time. The problem is after loading 2 times the app crash

Answer 1

The simple answer:

Returning a NaN from any of the height related delegate methods causes this error.

 tableView:heightForRowAtIndexPath:
 tableView:heightForHeaderInSection:
 tableView:heightForFooterInSection:

etc..

There may be other ways to produce this error but if you're working with UITableView--check this first!
