Multiline Navigationbar Title

Question

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?

Solution 1

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

Solution 2

This is doable in a storyboard. Just drag a UIView into the Navigation bar, then drag a UILabel onto it in the document outline, set lines to 2 and alignment to center.

Your navigationBar.frame.width was maybe not yet sized to fit the screen. You may want to override viewDidLayoutSubviews to detect the right frame.

Gonna require some tweaking to get it to behave more like how I want it to, but this did help.

I used navigationItem.titleView without setting the frame explicitly and it is working just fine.

@Rashwan L if you are define the frame of UILabel it will lead to the label to the left align so just leave the frame part and use as just a "let label = UILabel()". and it will work perfect and set its own self in the center aligned.

any hints on doing this in swiftui?

Why width 400points?
