I open a new window with window.open() to redirect users to the oauth login page. However, after successful login when the user is redirected back to my app the previous window with the window.open call does not close itself in ios.
On the iPad it would close the wrong window and on the iPhone it wouldn't close the window at all. The code works fine on Android and on desktop versions of Chrome and Firefox.
After much rooting about, I found a fix (posted below). If anyone has any better ideas or root causes, please post here.
After some searching, I found this tweet which posts a workaround - https://twitter.com/#!/gryzzly/statuses/177061204114685952 by @gryzzly
Copied here in full
window.close() doesn't work on iOS after window.open()ing or target="_blank"? do setTimeout(window.close, timeout); where timeout > 300.
This along with removing a .focus() in which I focus on the parent window before closing the new window completely solved the problem for me.
