Zombies detected - but the function has never been called

Question

What I've done?

In one of my children, UIViewControllerI implemented UITableViewand implemented the necessary functions UITableViewDelegate.

What I see?

The problem that I am facing is that I get EXC_BAD_ACCESS in the application whenever I restart the controller and click on any cell.

What have i tried?

I tried to place breakpoints in the didDeselectRowAtIndexPath: function , but it never reaches the breakpoint. I tried the Global Exception breakpoint, but it also didn't work. I checked with the tools and found that the zombie was detected during a call didDeselectRowAtIndexPath, but the control does not reach the function.

From all the Zombie magazines and images, it’s clear that you are accessing the liberated CountryListViewController. Keep an eye on CountryListViewControllerand make sure it is available during table view operations.

Best option: go to the Xcode Menu Product->Scheme->Mange Schemes->Edit (left bottom)-> Debug-> Diagnostics -> Check all the options -> then Run the project.

It will be a lighthouse to discover your disaster.
