IBAction inside UITableViewCell not called in iOS 9

Question

I have a custom UITableViewCell subclass which contains a few IBAction methods wired up from a nib.

Under iOS 8 everything works as expecte

Answer 1

I figured out the solution, hopefully this answer will save someone else the time.

I inherited this code base and it had some issues. The UITableViewCell's that were not working under iOS 9 were not using UITableViewCell nibs w/ a ContentView. Instead, someone had created a UIView nib and then pointed it to a custom UITableViewCell subclass. The nibs did not have a ContentView and apparently iOS 9 is a little more picky about that. This implementation worked fine under iOS 8 and there were no compiler or runtime errors or warnings.

The solution was to create a new UITableViewCell subclass and let Xcode auto create the nib for it. Then I copied over all of the UI and code from the old nib and pasted it into the ContentView of the new nib. I then had to fix up the constraints and rewire the connections to the custom subclass.
