objective c - sample code for collision detection in iPhone sdk

Question

Can you please suggest sample code for collision detection of two imageviews.

Thanks in advance.

Answer 1

You can Detect Collision between two images by making rect for those image views.

Consider my image-views being named: img_view1 and img_view2.

Image-views creation:

//For img_view1 rect
//parameters are x,y,width,height
CGRect image_rect1 = CGRectMake(img_view1.position.x,img_view1.position.y,100,100);

//For img_view2 rect
//parameters are x,y,width,height
CGRect image_rect2 = CGRectMake(img_view2.position.x,img_view2.position.y,100,100);

Collision detection:

if(CGRectIntersectsRect(image_rect1, image_rect2))
{
    NSLog(@"Rect is Intersecting");
}
