iPhone app crashes on startup

I had two apps in xcode, which i wanted to combine, so i started a new project and attempted to put the two apps together in this new one. Was this a really stupid thi开发者_开发技巧ng to do?

The app now crashes on start up and i have no idea why, i'm 99% the outlets are all connected. It uses xcdatamodel for storage and i've imported the right framework.

Can anyone think of any other things that could be going wrong?

I can attach a zip file with the project in if someone wouldn't mind having a look

Any help is massively appreciated!

Thanks

Looks like you have a text field connected to the application delegate in your main XIB. There is no such field defined on the real application delegate, which is why you’re getting the error.

Thats because you set main xib for app in info plist and set File Owner to appDelegate, while main xib file's owner is always UIApplication. Possible solution - add Object to .xib, set its class for appDelegate class and connect all unnecessary outlets. This worked for me.
