SplitView[1290:307] Could not load the \"canary04.png\" image referenced from a nib in the bundle with identifier \"xx.co.mycompany.ipad.SplitView\"
I was getting this error too. I will describe my scenario:
I have a subdirectory "img" which has some png's in it.
One of these png is "ic_timeprogress_000.png"
In the storyboard (visual designer) I had an imageView and the image was set to "ic_timeprogress_000.png" (not programatically). The designer showed the imageView correctly:

Although when running the app, the error was thrown.
So in the storyboard I changed (I insist: not programatically) from "ic_timeprogress_000.png" to "img/ic_timeprogress_000.png", which lead to not showing correctly the image in the designer but showing correctly when running (no error)

Although I alter imageView.image programatically, so this "initial image" isn't ever used.
