If you only want to draw horizontal or vertical line, you can just use UIView.

UIView *lineView = [[UIView alloc] initWithFrame:CGRectMake(<startingX>, <startingY>, <width>, <height>)];
lineView.backgroundColor = <desiredColor>;

//assume self is UIViewController or its sublcass
[self.view addSubview:lineView];
[lineView release];

Try this question. I know this references InterfaceBuilder, but you can dynamically add your custom view using Obj-C like mentioned here.
