This video will show you how to add Pinterest Pin It Button in iOS 7.
I have had a few people ask me about adding the Pinterest Pin It Button in iOS 7. Here is a video tutorial on how it is done. Apple have changed the tabs in iOS 7 which changes the way you can add buttons to the top of the Safari web browser.
Use the code above in the Pin It bookmark to allow you to Pin what ever you like on the web.
Hope this helps out, good luck.
