Description
We ran into an edge case in our use of TORoundedTableView (which is awesome, by the way):
If -[TORoundedTableView layoutSubviews] is called before the table view has been added to the view hierarchy, then the rounded corner images are not loaded in time, and the table view cells do not have a rounded corner appearance.
Why does this happen? Well, -[TORoundedTableView layoutSubviews] results in a call to -[TORoundedTableViewCapCell didMoveToSuperview]. When TORoundedTableViewCapCell tries to get the table view's roundedCornerImage in -[TORoundedTableViewCapCell didMoveToSuperview], it won't be able to because the table view hasn't loaded them yet (which happens only once the table has been added to the view hierarchy in -[TORoundedTableView didMoveToSuperview]).
My suggested fix is to eagerly call loadCornerImages inside of -[TORoundedTableView setUp], rather than lazily in -[TORoundedTableView didMoveToSuperview]. This solved the problem for us.
The question you're probably asking is, why would layoutSubviews be called before the table is added to the view hierarchy? We ran into a situation where we have a table header view that is sized using auto layout and, in order for it to display correctly when the table first appears, we have to call -[UITableView layoutIfNeeded] inside our view controller's viewDidLoad method. This triggers all of the layout, even though the table view doesn't have a superview yet.
Thanks for considering this fix.
