rac_signalForControlEvents not signaling in a UICollectionViewCell

Question

I have a bunch of UICollectionViewCells containing buttons. For some reason, my signal refuses to fire when a button is inside of a UICollectionViewCell. Switching to the normal addTarget:action:forControlEvents: will work, but not the RAC signal. I've had this happen in 2 different collection views, and 2 different custom collection cells.

All I'm doing is:

[[cell.button rac_signalForControlEvents:UIControlEventTouchUpInside] subscribeNext:^(id x) {
        // code to be executed here, which doesn't happen
}];

What am I missing?

Are you setting `rac_signal` in `tableView:cellForRow:atIndexPath` or in the cell's `init`? — Jeff Wolski, Jun 17 '14 at 01:00
I have a custom setup method that gets called during `collectionView:cellForItemAtIndexPath:`. So yes, the buttons are there. — MishieMoo, Jun 17 '14 at 02:40
This doesn't sound like a ReactiveCocoa-specific problem. Can you include any relevant parts of your custom setup method in your question? — erikprice, Jun 30 '14 at 15:13
Are there any taprecognizers which can prevent this action from happening? — Timur Kuchkarov, Aug 11 '14 at 07:33

try:

[[[cell.button rac_signalForControlEvents:UIControlEventTouchUpInside]
     takeUntil:cell.rac_prepareForReuseSignal]
     subscribeNext:^(id x) {
         // code to be executed here, which doesn't happen
     }];

That would just ensure that the same cell doesn't subscribe more than once, which would be the cause of the opposite issue to the one being encountered. – Charles Maria May 08 '15 at 08:50

I don't have enough reputation to comment so I will just comment here. It seems that there is something wrong with the button instance that is causing the signal not to fire. How are your buttons instantiated and where in the tableView:cellForRow:atIndexPath are you subscribing to the signal.
