Universal iOS Binary doesn't run on iPod touch

I am making a universal application (targeted device family --> iphone/ipad). It works perfectly fine in iphone and ipad but when it comes to iPod touch, I get no warnings or errors and my xcode shows it is running, but my iPod touch's screen turns into black.

I dont understand why it is behaving like that. Any ideas?

My console output is:

I had that problem, too. In the project's info plist file I had keys: "Main nib file base name (iPad)" set to "MainWindowForiPad" and "Main nib file base name (iPhone)" set to "MainWindowForiPhone". The solution was to add a third MainWindow key "Main nib file base name", which I set to "MainWindowForiPhone" also.

Like Kim said in the previous answer, the iPodTouch does not load the MainWindow nib associated with the iPhone's key, it loads the MainWindow under general key "Main nib file base name".

It is probably that you in your plistfile have designated the two .nib files to load on launch. One for the iPad and one for the iPhone. The ipod touch actually needs its own nib file to load.

Take a look at iPod Touch 4G thinks it's an iPad
