UIImage stretch only a portion

So, lets say i have this sprite:

mbm
bcb
mbm

where each letter is a portion. (m: margin; b: border, c:center)

and I want a class that is able to repeat the b's and c as long as it needs to complete the view so i get something like this:

mbbbbbbbbbbbbbm
bcccccccccccccb
bcccccccccccccb
bcccccccccccccb
mbbbbbbbbbbbbbm

Is there something that can do this already? If it doesn't exist, any ideas on how to implement it?

We can stretch the image using the below code :- Here we need the m..m must be in same size so we stretch the middle portion

UIImage *image = [UIImage imageNamed:@"img_loginButton.png"];
    UIEdgeInsets edgeInsets;
    edgeInsets.left = 3.0f; //Assume it is the pixel for starting 'm'
    edgeInsets.top = 0.0f;
    edgeInsets.right = 3.0f; //Assume it is the pixel for Ending 'm'
    edgeInsets.bottom = 0.0f;
    image = [image resizableImageWithCapInsets:edgeInsets];
//Use this image as your controls image

Could you not achieve this with this method ?

-(UIImage *)stretchableImageWithLeftCapWidth:(NSInteger)leftCapWidth topCapHeight:(NSInteger)topCapHeight

(see Apple UIImage Class Reference )
