    Swift 3

    UIGraphicsBeginImageContextWithOptions(size, true, UIScreen.main.scale)
    let context = UIGraphicsGetCurrentContext()
    context?.setFillColor(UIColor.green.cgColor)
    let image = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()
    return image

    How about this code?

    - (void)drawRect:(CGRect)rect {
    
        [super drawRect:rect];
        CGContextRef context = UIGraphicsGetCurrentContext(); 
    
        CGRect drawRect = CGRectMake(rect.origin.x, rect.origin.y,rect.size.width, rect.size.height);
    
        CGContextSetRGBFillColor(context, 100.0f/255.0f, 100.0f/255.0f, 100.0f/255.0f, 1.0f);
        CGContextFillRect(context, drawRect);
    }
