if a view controller got unloaded due to low memory pressure, will loadView be called again once it's is about to be shown again?

Question

I understand that the viewDidUnload will be called when the app is under low memory pressure, then when the related view/controller is about to be "active" again, will the loadView be called?

Yes. Place a breakpoint in loadView of your ViewController to see it yourself. You can simulate low memory condition in iOS simulator (Hardware -> Simulate memory warning). — 0x8badf00d, Jun 06 '12 at 01:20

Yes it will. Check out the Understanding How Views are Loaded and Unloaded section of the iOS View Controller programming guide to see a flow chart of how this works. The documentation for -loadView also notes that this method will be called when the view property is accessed, but is currently nil.
