View and Layer help

Question

I'm trying to make a simple program to help me learn layers that when a touch event happens a layer with a red bg color is created from the initialtouch point to the final. Here's my code so far for the touchmove method
CGPoint pt = [[touches anyObject] locationInView:self];
CGRect boundMe=CGRectMake(startLocation.x, startLocation.y, (pt.x-startLocation.x), (pt.y-startLocation.y));
addMe=[CALayer layer];
addMe.frame=boundMe;
CGColorSpaceRef rgbColorspace = CGColorSpaceCreateDeviceRGB();
CGFloat values[4] = {1.0, 0.0, 0.0, 1.0};
CGColorRef fml=CGColorCreate(rgbColorspace, values);
addMe.backgroundColor=fml;
[self setLayer:addMe];
However I keep on getting an error when i try to set the view(this is in a class which implements view) layer to the addMe layer. How do I do this?

I also tried moving thius code into the view controller class and I got it to atleast compile by using a UIView instead of a CALAyer but nothing is being drawn on the screen
