UICollectionViewCell cannot be targeted as a descendant/child and doesn't get styled properly. about interfacss HOT 5 CLOSED

When using nested declarations (or descendant selector chains etc), one must make sure that the leaf element (i.e. cell in this case) is added to the view hierarchy before applying styles. Currently, InterfaCSS doesn't provide any automatic handling for this (this could be accomplished with some method swizzling magic, but I'm trying to avoid such things a much as possible), which means it has to be done manually. One way of doing that is to apply the styles in the willDisplayCell method of the table view / collection view delegate, another way is to do it in the didMoveToSuperview method of a custom cell subclass.

I admit, the documentation around this could perhaps be a bit better...

I'm still not able to make the styling work properly. Sometimes it works, sometimes it does not and it's frustrating. Some tableviews don't get styled until I touch them or scroll them. Please advise. Thanks.

Sorry to hear. I'm just in the process of improving documentation, and I am also planning on releasing version 1.1 soon, which will bring improvements along with a bunch of new features.

In the meantime, try this:

• Log active declarations for a view using this call -[InterfaCSS logMatchingStyleDeclarationsForUIElement:]
• Have a look at the SimpleSample demo application - that one uses a UITableView (see PrototypeExampleViewController / prototypeExample.css) with at least a moderately complex style setup
• Try and simplify your selectors, i.e. instead using selectors like UITableView UITableViewCell .myClass, try using just .myCellClass for instance

With regards to tableview cells - I noticed that my styles didn't get
applied when a new cell is allocated (not recycled) -- in this case the
cell has no superview yet. In my case I manually called [tableView
addSubview:cell] inside my tableView:cellForRowAtIndexPath: if
cell.superview was nil. This allowed my styling rules to match - which
included class for my UITableView.

Closing this as there doesn't seem to be an underlying problem and likely just a usage issue, which is now documented on the wiki.

Feel free to reopen the issue in case there are indications that there still are issues with table/collection view cells.
