I am using the iAd suite with storyboards from Apple, as per this link... Apple iAd Storyboard documentation
It all works fine until I turn autolayout on. It builds fine but crashes on running. The output I get is:
2013-08-24 12:06:36.138 TabbedBanner[7272:c07] * Assertion failure in -[UIView layoutSublayersOfLayer:], /SourceCache/UIKit_Sim/UIKit-2380.17/UIView.m:5781 2013-08-24 12:06:36.139 TabbedBanner[7272:c07] * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Auto Layout still required after sending -viewDidLayoutSubviews to the view controller.

I know it is something to do with the subviews in storyboard but I dont know how to correct this error. I am pretty new to iOS and trying to teach myself so any help is appreciated. Many Thanks

Auto Layout defines your user interface using a series of constraints. Constraints typically represent a relationship between two views. Auto Layout then calculates the size and location of each view based on these constraints. This produces layouts that dynamically respond to both internal and external changes.
If you select Aspect Ratio for multiple items, Auto Layout chooses the width of one of the items for the numerator and the height of another item for the denominator. To change the initial aspect ratio, edit the Multiplier field of the Attributes inspector for the constraint.
layoutSubviews() The system calls this method whenever it needs to recalculate the frames of views, so you should override it when you want to set frames and specify positioning and sizing. However, you should never call this explicitly when your view hierarchy requires a layout refresh.
You always have to call [super layoutSubviews] last, if the intrinsic content size of a view will be changed. If you change the title of the button, the intrinsic content size of the UIButton will be changed, therefore the last call.
Add:
[self.view layoutIfNeeded]; to the end of this method
- (void)viewDidLayoutSubviews inside your BannerViewController
