Thread 1: Program received signal SIGABRT

Question

I'm just a newcomer in developing. I use xCode 4.6.3 and iOS 6 SDK. While I run my project, it crashes and I can see that:"Program received signal SIGABRT".

Please, give me some solutions of that problem.

Maybe, I'm stupid, but I do it about month.

Answer 1

like @Abizern says check your ISTableViewController whether it implements the topViewController. Probably you were trying to do a [UIViewController topViewController]. You need to do self.navigationController.topViewController. self.navigationController can change depending on your implementation.

Answer 2

The problem is explained by the crash report here:

[ISTableViewController topViewController]: unrecognized selector sent to instance

You are sending the method topViewController to an object that does not implement the method.

Which means somewhere in your code (not in what you have shown here) you are sending a message to an object which is not what you think it is.
