Summary:
As a developer I expect to be able to provide an overridden getter for -headerHeight or -footerHeight properties to specify the heights.

Steps to Reproduce:
1. Create a UIPrintPageRenderer subclass
2. Override -numberOfPages to return 1
3. Override -headerHeight to return a value > 0
4. Override -drawHeaderForPageAtIndex:inRect: to draw a box

Expected Results:
The -headerHeight getter should be called for determining the header height.

Actual Results:
The -headerHeight getter is never called. If you instead set it via self.headerHeight = value then this works.

Version:
7.0.5 (11B601)

Notes:
From this we can conclude that the implementation directly references the _headerHeight IVAR instead of retrieving the value via property.

This leads to developer confusion because reading the header you expect to be able to override getters to provide such values, especially because you need to create a new subclass for your custom printing implementation.

Configuration:
iOS 7
