-(void) bringSublayerToFront:(CALayer*)layer
{[layer removeFromSuperlayer];[self insertSublayer:layer atIndex:[self.sublayers count]-1];}-(void) sendSublayerToBack:(CALayer*)layer
{[layer removeFromSuperlayer];[self insertSublayer:layer atIndex:0];}Note: if you don‘t use ARC, you may wish to
add [layer retain] at top and [layer
release] at bottom of both functions to make
sure layer is not accidentally destructed in a case it
has retain count = 1.
