Can someone please help!

When I build and go, I get no errors and the app launches in the simulator. As soon as it completes launch, it terminates. I get this "Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[MainView initWithCoder:]" How do I fix this?

Step 1 - Search for the error message in your code. Are you doing initWithCoder: anywhere? If so, start in that general area for debugging.

Step 2 - If that doesn't turn anything up, start looking at uses of MainView that might relate to #1. init, load, etc.

Step 3 - (arguably Step 1) Start adding log messages to figure out where it dies.

The initWithCoder method is the method that is called to create an object from a nibfile.

It sounds like you have a custom class MainView, that is being created from a nibfile. There must be something wrong with the way the object is loaded from the nibfile. Look closely at your nib, checking for references to objects who's types aren't defined, etc.

I think that is the error I get when I delete or change an IBOutlet after it has already been hooked to an object in Interface Builder. Go into IB and check all your connections to see if any of them are to IBOutlet names that no longer exist in the code.

Do you get any errors when you build ?
