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

The easiest way in your case (horizontal line) is to add a sub-view with black background color and frame [0, 200, 320, 1].
Code sample (I hope there are no errors - I write it without XCode):

UIView *lineView = [[UIview alloc] initWithFrame:CGRectMake(0, 200, self.view.bounds.size.width, 1)];
lineView.backgroundColor = [UIColor blackColor];
[self.view addSubview:lineView];
[lineView release];
// You might also keep a reference to this view 
// if you are about to change its coordinates.
// Just create a member and a property for this...

Another way is to create a class that will draw a line in its drawRect method (you can see my code sample for this here).

EDIT: Added the code sample for creating a sub-view

Answer 2

You could also draw your own line but there are almost no benefits to the subview way
