I am developing an application where i want that u开发者_开发问答pon a press of button iPhone settings screen should open.

Is there any restriction from apple to access it?

Is it possible or not,If yes then how?

No you can't do that. However as an alternative you can use This Framework to mimmick the settings app, so that you can set your settings from the official settings app, or from a in app settings page.

No, it's not possible using public API's.

However there exists a number of frameworks that allows you to access the settings bundle directly from within your application. Take a look at this SO question for more information.
