Draw line in UIView

Question

I need to draw a horizontal line in a UIView. What is the easiest way to do it. For example, I want to draw a black horizontal line at y-coord=200.

I am NOT using Interface Builder.

Answer 1

Maybe this is a bit late, but I want to add that there is a better way. Using UIView is simple, but relatively slow. This method overrides how the view draws itself and is faster:

- (void)drawRect:(CGRect)rect {
    [super drawRect:rect];

    CGContextRef context = UIGraphicsGetCurrentContext();
    CGContextSetStrokeColorWithColor(context, [UIColor redColor].CGColor);

    // Draw them with a 2.0 stroke width so they are a bit more visible.
    CGContextSetLineWidth(context, 2.0f);

    CGContextMoveToPoint(context, 0.0f, 0.0f); //start at this point

    CGContextAddLineToPoint(context, 20.0f, 20.0f); //draw to this point

    // and now draw the Path!
    CGContextStrokePath(context);
}
