UIbutton deallocated in custom UITableViewCell - ios

Question

Using ARC (Automatic Reference Counting), I have a UIButton in a subclassed UITableViewCell. The table view controller implements the IBAction which is hooked up to the UIButton. In the subclassed cell's xib, the same table view controller is the File's Owner.
The problem occurs when I run the app and click on the button, I get an EXC_BAD_ACCESS. It's clearly visible on the iPhone screen, so it is being allocated at some point.
Any idea what the problem could be? Thanks in advance!
EDIT1:
Note: I have env variable NSZombieEnabled set to true.
Here's the console:

Answer 1

Figured it out. I was using UINib's instantiateWithOwner: options: to load the nib of the custom UITableViewCell. I was setting the owner to nil. Setting the owner to my view controller fixed it. Also, my view controller is the File's Owner of that UITableViewCell nib. I'm guessing because the view controller and nib were not properly linked, ARC did not see a reason to keep the view around.

I am not sure but I have a feeling your problem is in the selector you are passing to the button.
Try to see if you are using a selector with ":" to a method with out parameters.
If you are using selector that looks like this:
#selector(method:)
Then is is expected that "method" will take parameters:
-(IBAction)method:(UIButton)sender{
}
if your function is not taking any parameters:
-(IBAction)method{
}
then your selector should look like that:
#selector(method)
