Your code for adding the view controllers as children is really skanky. I'd start by straightening it out. Remember, each time you add a child controller, your job is to send "add" (and "willMove" is sent automatically) and then "didMove". When you remove a child controller, your job is to send "willMove" (with nil param) and then "remove" (and "didMove" is sent automatically). You must interleave the movement of the subview to or from the interface into the middle of this procedure. So, the dance for adding a child must go: * "add" * put it in the interface if it's going into the interface * "didMove" See my examples, both in the book online and in the downloadable code examples, for the iOS 5 revision of my book. m. -- matt neuburg, phd = m...@tidbits.com, <http://www.apeth.net/matt/> A fool + a tool + an autorelease pool = cool!
