Question

I am getting this error when I load a new tableview onto my navigational stack.
All of the data displays in the table that I am parsing onto it however once that has finished the app stops working and I get this error.

Just wondering if anyone knows what the problem might be? or how I might be able to debug it?

If you need more code let me know I just don’t know what to provide because I’m not sure what the error refers too.

-[VehicleResultViewController stopAnimating]: unrecognized selector sent to instance 0x6a2a680

Answer 1

You need to post more code.

In general, an unrecognized selector error occurs when you try to invoke a method on a class that does not have the method implemented.

Is VehicleResultViewController a UITableViewController/UIViewController? Have you added the stopAnimating method? UIViewController and it’s subclass, UITableViewController do not have a stopAnimating method in their default implementation.

If it’s a UITableViewController or a UIViewController and you haven’t added a stopAnimating method, then you’re calling a method that VehicleResultViewController does not have hence the crash.

It’s really hard to answer your question more accurately until you:

1. Post code for where you call the method
2. Post the header file for VehicleResultViewController so we can see what kind of class is it (or you could just tell us).

It could also be (and more probably is) that you have a UIActivityIndicatorView in your code which you want to stop spinning. In that case, are you sure it’s named ‘vehicleResultViewController’? Whatever your UIActivityIndicatorView is named, try calling:

[whatever_your_activity_indicator_view_is_named stopAnimating];
