I try to drag the UITextView over to my ViewController.h and when I try to do it a message pops up that says ""UIViewController.h" is locked for editing and you may not be able to save your changes. Do you want to unlock it?"

I click Unlock and then another message pops up that says

"Could not add write permission to the file because you do not own it. Try modifying the permissions of the file in the Finder or Terminal."

I've tried to unlock it in Finder and Terminal and nothing works. Can anyone help?

Also if nobody can help, does anyone know how someone would save text written in the textview object on the iPhone?
