TUIScrollView animation about twui

[mrjjwright]

I think I might have solved my own issue here (as I was making my bed this morning it hit me). I forced the current runloop to run after cycling in all the necessary subviews and very importantly not setting the contentSize of the scrollview until after the run loop completes and adds the needed subviews for the animation. In order to get the run loop to fire I used the trick from this SO question:

 skipLayout = YES;
 [[NSRunLoop currentRunLoop] runMode: NSDefaultRunLoopMode beforeDate: [NSDate date]];
 skipLayout = NO;

If skipLayout is set I just returned from layoutSubviews so that the views I just added are not immediately removed by my recycling layout code. Forcing the run loop to run made sure that all subviews were on the screen for the animation. After this I performed the resize animated layout. I updated the code on github if anybody is interested. I will leave this question open for a while to gain some further insight.
