How to add a multiline title bar in UINavigationController
(2 answers)
Closed 4 years ago.
I am trying to display names on a custom navigation title
For long names it is truncating, How do I display the text in multiple lines for long names, Here is the code I used for custom titleView
nameLabel.font = UIFont(name: “Arial-Medium", size: 19)
nameLabel.textAlignment = .center
nameLabel.numberOfLines = 2
nameLabel.adjustsFontSizeToFitWidth = true
nameLabel.lineBreakMode = .byCharWrapping
self.navigationItem.titleView = nameLabel
You can really control this behaviour if the text is very very long. Depending on the font size, you might be able to show full text but that too if is not too long (does not exceeds height of navigation bar/label). However here are few things might want to change :
nameLabel.numberOfLines = 2
nameLabel.lineBreakMode = NSLineBreakMode.ByTruncatingTail
nameLabel.adjustsFontSizeToFitWidth = true
nameLabel.minimumScaleFactor = 0.4

I try to setup a custom button with UIImage and UILabel
After setting up constraints, I started testing this button and noticed strange behavior
UILabel in UIButton code:
private var title: UILabel = {
var label = UILabel()
label.translatesAutoresizingMaskIntoConstraints = false
label.font = UIFont.boldSystemFont(ofSize: 14)
label.numberOfLines = 0
label.adjustsFontSizeToFitWidth = true
label.minimumScaleFactor = 0.5
return label
}()
When I set title for example "Hfpdktxtybz", UILabel works amazing!
One word takes one line:
But if I try set title for example "Развлечения", UILabel truncates the word.
One word is split into two lines:
Why for English language label work is correctly, but for Russian language truncates the word? How to fix it?
The number of characters is the same
The problem is, as said in the comments, that characters don't necessarily have the same width.
lllll
AAAAA
aaaaa
The above example clearly shows characters do not have the same width although they have same character count.
So Autolayout calculates the UILabel real width and it has only one option in order to satisfy your constraints. That is to split it into 2 lines.
If you don't want this to happen consider changing UILabel priority numberOfLines.
if you use storyboard
if you use swift programmatically.
label.numberOfLines = 2
I am using CosmicMind - Material Framework to create a Card. titleLabel and DetailLabel do not wrap to a new line.
My question is: What do I need to do to accomplish such task and is it supposed to be automatically adjusted by the framework?
This is what I have so far:
let card = Card()
var heartIcon = IconButton()
heartIcon = IconButton(image: Icon.favoriteBorder, tintColor: Color.red.base)
//Title Bar
let toolbar = Toolbar(rightViews: [heartIcon])
toolbar.title = cardData.cardTitleText
toolbar.titleLabel.textAlignment = .left
toolbar.titleLabel.numberOfLines = 0
toolbar.detail = "Company: " + cardData.cardTitleSubtitle
toolbar.detailLabel.font = RobotoFont.regular(with: 14)
toolbar.detailLabel.textColor = Color.grey.base
toolbar.detailLabel.textAlignment = .left
toolbar.detailLabel.numberOfLines = 0
And this is my output:
Update:
I managed to achieve what I wanted by increasing the size of the toolbar frame.
toolbar.frame = CGRect(x:0,y:0,width: view.frame.width,height: 100)
My goal was to at least show 2 lines of text.
Thanks!
I have no experience with the CosmicMind framework but usually, the label.numberOfLines property defines the maximum number of lines that the label text can have. You can set it to 2 instead of 0 and it should wrap.
I'm wanting to move my labels wherever I want on my external display. (eg. displayRunsLabel at the top and centered or perhaps 40px from right and top)
I have my labels showing on the screen. I'm currently using text alignment.
What's the best way to do this?
Here's my external display:
ExternalDisplayScreenshot
Here's the code:
// CUSTOMISE VIEW
secondScreenView.backgroundColor = UIColor.black
displayWicketLabel.textAlignment = NSTextAlignment.left
displayWicketLabel.font = UIFont(name: "Arial-BoldMT", size: 200.0)
displayWicketLabel.textColor = UIColor.white
displayWicketLabel.frame = secondScreenView.bounds
secondScreenView.addSubview(displayWicketLabel)
displayRunsLabel.textAlignment = NSTextAlignment.center
displayRunsLabel.font = UIFont(name: "Arial-BoldMT", size: 200.0)
displayRunsLabel.textColor = UIColor.white
displayRunsLabel.frame = secondScreenView.bounds
secondScreenView.addSubview(displayRunsLabel)
displayOversLabel.textAlignment = NSTextAlignment.right
displayOversLabel.font = UIFont(name: "Arial-BoldMT", size: 200.0)
displayOversLabel.textColor = UIColor.white
displayOversLabel.frame = secondScreenView.bounds
secondScreenView.addSubview(displayOversLabel)
}
The position of a label or any other UIView is the origin of its frame, which is a CGPoint representing its top left corner.
So, you are currently saying:
displayWicketLabel.frame = secondScreenView.bounds
displayRunsLabel.frame = secondScreenView.bounds
displayOversLabel.frame = secondScreenView.bounds
Well, that's pretty silly, because you have given all three labels the same frame! Thus they overlay one another, and (as you rightly say) you can only read them by giving them different text alignments.
Instead, give them each a different frame — one that puts the label where you want it. For example:
displayWicketLabel.sizeToFit()
displayWicketLabel.frame.origin = CGPoint(x:30, y:20) // or whatever
displayRunsLabel.sizeToFit()
displayRunsLabel.frame.origin = CGPoint(x:30, y:100) // or whatever
displayOversLabel.sizeToFit()
displayOversLabel.frame.origin = CGPoint(x:30, y:200) // or whatever
Now, having said all that, a clear flaw in the code I just showed you is that we have hard-coded the positions arbitrarily, without taking account of what the size of the window is (the external display). For that reason, a much better way would be for you to learn about auto layout, which will let you lay the three labels out in nice positions automatically based on the size of the window.
Is it possible to have a textfield's placeholder text opaque while its background is set to be transparent, eg. if I choose some background color, and set alpha to some value, like this:
the placeholder text becomes transparent as well. But I want it opaque. So, is this achievable, preferably using storyboard ? Or at least through the code.
If it is unclear what I am trying to achieve, just let me know , and I'll post an image with an example.
You can set the color's transparency instead of the UITextField's alpha. Open the color drop down and select "Other". A color picker will open up. At the bottom of the color picker you can change the opacity.
In Swift you can obtain the placeholder element with:
let placeHolder = textField.value(forKey: "placeholderLabel") as! UILabel
placeHolder.textColor = .blue
placeHolder.isOpaque = true
and make all customizations you prefeer..
You can set the UITextView.background = .clear
I'm providing a little more code so it'll be easier to setup it programmatically, this is a ready-to-use sample.
private lazy var textField: UITextView = {
let textField = UITextView()
textField.translatesAutoresizingMaskIntoConstraints = false
textField.font = UIFont.systemFont(ofSize: 14)
textField.isEditable = false
textField.textAlignment = .center
textField.isScrollEnabled = false
textField.backgroundColor = .clear // this is the line that answer you question
textField.text = """

"""
return textField
}()
Just remember to set the constraints and add the subview into your superview .addSubview(TextField)

Multiple lines of text in UILabel
(26 answers)
Closed 5 years ago.
I am having a problem resizing the font size to fit a label and not splitting any words.
I have a label that will change its content dynamically based on an array of strings.
The label could have any number of lines. What I want is for the font size to be as big as possible while fitting the label AND not splitting any words.
I made the font size very big on storyboard.
The label is placed on the view using Auto-Layout.
For example for a string "Most definitely" if I use this code:
answerLabel.numberOfLines = 0
answerLabel.adjustsFontSizeToFitWidth = true
answerLabel.lineBreakMode = .byTruncatingTail
I get strings like:
Most(line 1)
Definitel(line 2) y(line 3)
If on the other hand I do
answerLabel.numberOfLines = 0
answerLabel.adjustsFontSizeToFitWidth = true
answerLabel.lineBreakMode = .byWordWrapping
I get a string "Mo" in big letters
Obviously what I am looking for in that case is Most(line 1) definitely(line 2).
Thanks in advance for any help.

Set number of lines zero for dynamic text information, it will be useful for varying text.
var label = UILabel()
let stringValue = "Multiline UILabel not wrapping words correctly"
label.text = stringValue
label.numberOfLines = 0
label.lineBreakMode = .byTruncatingTail // or .byWrappingWord
label.minimumScaleFactor = 0.8 . // It is not required but nice to have a minimum scale factor to fit text into label frame
