How to find whether two objects intersect each other?

Question

I used the following code to create and animate the object

//For creating two imageview 
UIImageView *bbl1Obj=[[UIImageView alloc]initWithFrame:CGRectMake(34         


        

Answer 1

Use CGRectContainsPoint which gives the objects intersect.

    if(CGRectContainsPoint([bbl1Obj bounds], CGPointMake(bbl2Obj.frame.origin.x, bbl2Obj.frame.origin.y)))
    {
NSLog(@"intersect");
    }
