复制iPhone的照片应用

Question

I'm looking to replicate the iPhone Photo's app behaviour, where it letterboxes the picture when zoomed out, but when zoomed in the bars no longer exist. What view layout (and math) do I need to achieve this?

Thanks,

This MWPhotoBrowser github project is probably your best bet. We looked at doing the same but it really was quite a big job, so we used this instead. Saved lots of time.
