How can i set the bass, or other kind of Equalizer programatically for my iphone app? Are there ready frameworks or methods available?? Kindly please provide a reference..
No there is no way you can get a direct settings/Equalizer Settings in AVAudio Player.
It is an framework provided by Apple, so all you can access is all you get in class reference.
So I would like to go through Class Reference and there is no point where it says you can access the Equalizer settings.
Here is the link for it.

Hope this helps.
EDIT-1:
If you are wanting to use some other library which gives you extensive access to settings and which can even give sounds effects that even a DJ would be pleased by then you can use
BASS Audio Library
This is a paid library but it is worth buying if you really want good and effective sound effects and access to all the settings.
