I want to dynamically create an image for a UITableViewCell which is basically a square with a number in it. The square has to be a colour (specified dynamically) and contains a number as text inside it.

I have looked at the CGContextRef documentation, but can't seem to work out how to get the image to fill with a specified certain colour.

This is what I have been trying so far.

-(UIImage*)createCellImageWithCount:(NSInteger)cellCount AndColour:(UIColor*)cellColour {

    CGFloat height = IMAGE_HEIGHT;
    CGFloat width = IMAGE_WIDTH;
    UIImage* inputImage;

    UIGraphicsBeginImageContext(CGSizeMake(width, height));
    CGContextRef context = UIGraphicsGetCurrentContext();
    UIGraphicsPushContext(context);

    // drawing code goes here
        // But I have no idea what.

    UIGraphicsPopContext();
    UIImage* outputImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return outImage;
}
