ARC converts the application with the last call .cxx_destruct

Question

Below is a trace of the thread stack of my application that crashed. I recently converted my application to ARC. The final call is the cxx_destruct HomePageViewController, which is the rootviewcontroller of one of my tabs in the tabviewcontroller. The appdelegate implementation file is not supported by ARC for compilation, so the HomePageViewController is freed up after it is added to the tabbarviewcontroller in the appdelegate file. The HomePageViewController implementation file has an ARC flag for compilation. Can anyone lead me in the right direction

Answer 1

The comment above is correct; you seem to manually call release on this view controller, which is prohibited by ARC. Just delete this call and you should be fine.

Also, why did you exclude the application delegate from ARC? In this class, there should not even be much code except the main core, if you use Core Data ...
