问题
After a lot of googling and researching, I have found out that iOS blocks autoplaying of html5 audio and video. Audio and Video can only be played as a response to a click event.
Now, I have another problem. I run a music website with a lot of user generated playlists. After clicking play, I make an ajax request to fetch the track URLs, and then load them and play them. iOS doesn't consider this as a synchronous click event to play music, so the music doesn't start playing on clicking the play button. I have to click on the player control's pause and play buttons to make it start playing (which basically just use pause() and play()).
I just can't think of what to do. Loading all the MP3 URLs before hand before the click event is not feasible. Is there any other way to get this done?

I know this is an ancient question, but for people coming across this there is a straightforward solution which is to play a short, silent sound directly from the click handler. Ideally, this would be a sound file you have already fetched and cached.
After that you'll be able to initiate playback from other handlers, even those without direct user interaction. (such as your AJAX/XHR response)

Okay, after a bit of fooling around and researching, I figured out that the only way to do a playlist fetch and play in one click, is to use a synchronous request instead of an AJAX request. The page will freeze up while the request loads, but it seems to be the only way out.
