Does overflow:hidden applied to <body> work on iPhone Safari?

I had a similar issue and found that applying overflow: hidden; to both html and body solved my problem.

html,
body {
    overflow: hidden;
} 

For iOS 9, you may need to use this instead: (Thanks chaenu!)

html,
body {
    overflow: hidden;
    position: relative;
    height: 100%;
}

body {
  position:relative; // that's it
  overflow:hidden;
}

Some solutions listed here had some strange glitches when stretching the elastic scrolling. To fix that I used:

body.lock-position {
  height: 100%;
  overflow: hidden;
  width: 100%;
  position: fixed;
}
