I'm putting together a demo in Xcode 5.0.2 for iOS7 and have wired up some scenes and have some buttons, some view controller classes and some segues. Nothing out of the ordinary. What I've never seen before is that intermittently - on some builds - when performing a segue, the next view controller is all black after the push. But not all the time. Sometimes it works in the simulator, sometimes it works on the device.
I've never seen this before in 3 years of programming for iOS.
Looking around StackExchange, I see answers that don't explain why it's happening in my case. I don't have a (void)loadView method in either of my classes and this wouldn't explain why it's intermittent.
Has anyone else seen this behaviour before?
Thanks in advance.
EDIT 01: turning off AutoLayout appears to fix this but opens up other problems. I still have no idea why this is happening.
EDIT 02: multiple view outlets issue, not AutoLayout related.
