I am trying to set the title label in my navigation bar to allow multiple lines. I have custom navigation controller code that I am placing the multiline code into. I know that the code already there works, but my multiline part is not working.
let titleLabel = UILabel()
titleLabel.frame = CGRectMake(0, 0, self.navigationBar.frame.width, self.navigationBar.frame.height * 2)
titleLabel.numberOfLines = 0
titleLabel.lineBreakMode = .ByWordWrapping
navigationItem.titleView = titleLabel
But the text still runs off at the end. I've also tried putting this into the individual view controller itself, adding self.navigationController?.
in front of navigationItem
with the same results.
Is there something I'm missing in my code that would keep the title label from using multiple lines?
Here is a code example of how you can create a multiline navigationBar title
let label: UILabel = UILabel(frame: CGRectMake(0, 0, 400, 50))
label.backgroundColor = UIColor.clearColor()
label.numberOfLines = 2
label.font = UIFont.boldSystemFontOfSize(16.0)
label.textAlignment = .Center
label.textColor = UIColor.whiteColor()
label.text = "This is a\nmultiline string for the navBar"
self.navigationItem.titleView = label
Swift 5.x:
let label = UILabel()
label.backgroundColor = .clear
label.numberOfLines = 2
label.font = UIFont.boldSystemFont(ofSize: 16.0)
label.textAlignment = .center
label.textColor = .white
label.text = "This is a\nmultiline string for the navBar"
self.navigationItem.titleView = label
Use this to get the label position exactly as you want it:
let labelWidth = navBar.bounds.width - 110
let label = UILabel(frame: CGRect(x:(navBar.bounds.width/2) - (labelWidth/2), y:0, width:labelWidth, height:navBar.bounds.height))
label.backgroundColor = UIColor.clear
label.numberOfLines = 0
label.font = UIFont.boldSystemFont(ofSize: 13.0)
label.textAlignment = .center
label.textColor = UIColor.black
label.lineBreakMode = .byWordWrapping
label.text = loadedName
navBar.topItem?.title = nil
navBar.addSubview(label)
the 110 value in the top line is the spacing you want either side of the label.
swift 5+ very easy solution
func titleMultiLine(topText: String, bottomText: String) {
// let titleParameters = [NSForegroundColorAttributeName : UIColor.white,
// NSFontAttributeName : UIFont.<Font>]
// let subtitleParameters = [NSForegroundColorAttributeName : UIColor.<Color>(),
// NSFontAttributeName : UIFont.<Font>]
let titleParameters = [NSAttributedString.Key.foregroundColor : UIColor.white]
let subtitleParameters = [NSAttributedString.Key.foregroundColor : UIColor.white]
let title:NSMutableAttributedString = NSMutableAttributedString(string: topText, attributes: titleParameters)
let subtitle:NSAttributedString = NSAttributedString(string: bottomText, attributes: subtitleParameters)
title.append(NSAttributedString(string: "\n"))
title.append(subtitle)
let size = title.size()
let titleLabel = UILabel(frame: CGRect(x: 0, y: 0, width: size.width, height: size.height))
titleLabel.attributedText = title
titleLabel.numberOfLines = 0
titleLabel.textAlignment = .center
navigationItem.titleView = titleLabel
}
Function Calling
self.titleMultiLine(topText: "I am top text Title", bottomText: "bottom text")
