It make sense if you think about it: it's asking for sizes so that scroll view
contentSize can be set
The table view needs to call -heightForRowAtIndexPath: for each cell in the
table, at the very least, so that it knows how tall the table is so that it can
set -contentSize on it's underlying scroll view.
For performance, you could calculate and cache the cell heights in an array

How do the results differ between what you saw before and after saving the
document? Is everything wrong? or just the scaling, the rotation, what?
And to draw an object, are you using an affine transform just to rotate it or

-drawInRect draws the image into the destination rectangle, stretching or
shrinking as necessary to get it to fit. If you want to preserve the aspect

How about providing a singleton class method? Then you just include
WebServiceInterface.h where needed. No need to have a global variable.

reaching explicitly out to other view controllers to tell them to do something.
Depending on your specific situation, interested objects could register for

Custom view that sits on top of a UIImageView? Implement -drawRect: and a
