Augmented Reality in iPhone
<p>I am trying to make an iPhone app which uses AR technology. In this i am required to draw an AR line on the ground. The condition is that the device bottom edge should be in contact with the bellybutton region and this straight line should be drawn from our feet.</p>

<p>For grabbing the ground view, i think the camera functionality which is provided, its api could be used. </p>

<p>So, anybody can please suggest me how to do camera grabbing functionality and which api or framework i should use to implement AR.</p>

<p>And one more thing in which version of ios, this AR functionality is added.</p>

<p>Any help is highly appreciated.</p>
