Set background color for only part of UIView

Question

I want the bottom (not quite half) of my UIView to be a different color than the top.

I\'m wondering if I should create a CGRect and then color that? Is this along the r

You can use this code. Please change the CGRect according to your desire.

- (void)drawRect:(CGRect)rect
{
    CGContextRef context = UIGraphicsGetCurrentContext();

    CGRect topView = CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, [UIScreen mainScreen].bounds.size.height / 2);
    CGRect bottomView = CGRectMake(0, [UIScreen mainScreen].bounds.size.height / 2, [UIScreen mainScreen].bounds.size.width, [UIScreen mainScreen].bounds.size.height / 2);

    UIColor * grayColor = [UIColor colorWithRed:230.0/255.0 green:230.0/255.0 blue:230.0/255.0 alpha:1.0];

    CGContextSetFillColorWithColor(context, grayColor.CGColor);
    CGContextFillRect(context, bottomView);

    CGContextSetFillColorWithColor(context, [UIColor yellowColor].CGColor);
    CGContextFillRect(context, topView);
}
