Creating a horizontal line

Question

I have two labels that are stacked. If I want a horizontal line between them, is there any other way besides using an image with a UIImageView?

Answer 1

Create a UIView with a black background that is 1 pixel high and 320 pixels wide.

Answer 2

Use a UIView:

UIView * separator = [[UIView alloc] initWithFrame:CGRectMake(x, y, 320, 1)]; separator.backgroundColor = [UIColor colorWithWhite:0.7 alpha:1]; [self.view addSubview:separator]; [separator release]; 

Answer 3

While Jasarien's solution is nice and simple, it doesn't create an actual 1 pixel hairline, but a 2 pixel wide line on 2X devices.

I found a blog post on how to create the real 1 pixel thin hairline. We need a utility UIView subclass. For Swift that would be:

import UIKit

class HairlineView: UIView {
    override func awakeFromNib() {
        guard let backgroundColor = self.backgroundColor?.CGColor else { return }
        self.layer.borderColor = backgroundColor
        self.layer.borderWidth = (1.0 / UIScreen.mainScreen().scale) / 2;
        self.backgroundColor = UIColor.clearColor()
    }
}
