I have a font called Poppins-bold (you can find it on Google Font) that in iOS 11 display incorrectly. Here you can see a screenshot with iOS 10:
And screenshot in iOS 11:
Four fonts displayed are:
Poppins Bold with a Storyboard
Helvetica Bold with a Storyboard
Poppins Regular via code
Poppins Bold via code
And my error is with Poppins Bold via code. My code is:
label1.font = UIFont(name: "Poppins-Regular", size: 30)
label2.font = UIFont(name: "Poppins", size: 30)
How is it possible?
I've printed font in the projects and this is my result:
Font Family Name = [Poppins]
Font Names = [["Poppins-Regular", "Poppins"]]
Your printout explains the problem. "Poppins" is a family name. If you have both Poppins Regular and Poppins Bold, the family name defaults to meaning the regular font. This prevents you from accessing the Poppins Bold font by its name, which (unfortunately) is "Poppins".
Instead, use the font descriptor to change Poppins Regular to Poppins Bold:
let font = UIFont(name: "Poppins-Regular", size: 30)!
let desc = font.fontDescriptor
let desc2 = desc.withSymbolicTraits(.traitBold)!
let font2 = UIFont(descriptor: desc2, size: 0)
self.lab.font = font2
I might be a bit late, but in case your question is still relevant, problem can be solved by updating font files from https://fonts.google.com/specimen/Poppins. You will also need to use "Poppins-Bold" font name instead of "Poppins".
Hi I am currently setting up views below:
func setupViews() {
self.numberLabel = UILabel(frame: .zero)
self.addSubview(self.numberLabel)
self.numberLabel.snp.makeConstraints { (make) in
make.edges.equalToSuperview()
}
self.numberLabel.textAlignment = .center
self.numberLabel.textColor = UIColor.white
self.numberLabel.adjustsFontSizeToFitWidth = true
self.numberLabel.minimumScaleFactor = 0.5
}
I would like to change the font of the text inside the label to bold font, however it's difficult to see an easy way to do so, following the syntax principles above.
For Swift 5+ and upto latest version (Swift 5.4) period
Stylizing the Font (SystemFont)
UIFont.systemFont(ofSize: 17, weight: .medium)
where you can set .weight provides various UIFont.Weight properties as given below
.black
.bold
.heavy
.light
.medium
.regular
.semibold
.thin (Looks very cool and I guess Apple also uses this somewhere)
.ultralight
Note that it's only for default SystemFont only.
AppleDocumentation
Changing the Font
UIFont(name: "HelveticaNeue-Thin", size: 16.0)
where name includes the FontName
you can also specify .weight by writing - before weight (If that font supports that weight as Not all fontFamily supports all
types of UIFont.Weight)
This is more preferable method to use for stylising the font if
you're not using default SystemFont
You just set the font property of the label, for example:
numberLabel.font = UIFont.systemFont(ofSize: 10, weight: 200)
I'm amazed there's nothing on SO already on this.
Take a look at the reference docs too: https://developer.apple.com/documentation/uikit/uilabel
By the way, unless you are operating within a closure, or other contexts where the semantics are ambiguous (e.g. in an initialiser) you don't generally need to use self. prefix.
Hope that helps.
If your just using the system font you can also do
UIFont.boldSystemFont(ofSize: 16.0)
Selecting whichever size you need
Here's the documentation on it
I'm trying to change my font from medium to regular, but I keep getting nil when setting the font type for NSFontAttributeName. I can get the font as medium without a problem, but when I try to set it to regular programmatically, my program crashes because the font is nil.
let attrsUnselected = [NSFontAttributeName: UIFont(name: "Roboto-
Regular", size: 15)!, NSForegroundColorAttributeName : UIColor.gray]
let attrsSelected = [NSFontAttributeName: UIFont(name: "Roboto-Medium",
size: 15)!,NSForegroundColorAttributeName : UIColor.black]
Before my app crashes, I can see that the font is actually set to regular.
I don't know how many different ways I get validate that the font has been imported into the project.
Check the following:
The font is added to the target
Its listed under "Copy Bundle Resources" on your target
And does it show up in the list of available fonts when you print them?
I've read around for different solutions but nothing seems to work. This code creates a nil exception:
[NSFontAttributeName: UIFont(name: "Raleway-SemiBold", size: 16)!]
I have the fonts installed properly and they show up correctly in the app (target is set).
I tried to add the application provided fonts in the plist but nothing happened. I can't edit the items in the array: (they are item0 : string : Raleway-SemiBold.tff).
So basically I'm stuck... Sometimes Swift and Apple environments are great for a programmer, other times (most of the time), they are sooo faulty and need so many workarounds to reach the expected results.
Many thanks in advance for any help.
You're getting an exception because UIFont(name: "Raleway-SemiBold", size: 16) returns nil and you're force-unwrapping it with !.
Instead, use conditional unwrapping:
if let font = UIFont(name: "Raleway-SemiBold", size: 16) {
let attributes = [NSFontAttributeName: font]
// do something with attributes
} else {
// The font "Raleway-SemiBold" is not found
}
You can use UIFont's familyNames() and fontNamesForFamilyName(_:) methods to get the exact string required.
Swift 4
if let font = UIFont(name: "Raleway-SemiBold", size: 16) {
let attributes = [NSAttributedStringKey.font: font]
// do something with attributes
} else {
// The font "Raleway-SemiBold" is not found
}
You Just have to write the correct string name of your font.
Don't write the name that is font file name. (like bodoni-mt-bold.ttf its the file name i have downloaded from any site).
To find out the exact font name follow the image below.
Go to your label select it and go to custom font and then see the name of your custom font in its family. if your custom font name is there then copy that name and past it as a string where u wanna use it. (Note you can't copy font name text you have to write else where then past it)
For Swift 3, here's an update that worked for me:
First you'll set up the font and then create a textAttribute with the NSFontAttributeName:
let font = UIFont(name: "Raleway-SemiBold", size: 16)
textAttribute = [NSFontAttributeName: font as Any, NSForegroundColorAttributeName: UIColor.black]
You can then apply textAttribute to your label, textfield etc.
I am trying to change the font of a UIButton using Swift...
myButton.font = UIFont(name: "...", 10)
However .font is deprecated and I'm not sure how to change the font otherwise.
Any suggestions?
Use titleLabel instead. The font property is deprecated in iOS 3.0. It also does not work in Objective-C. titleLabel is label used for showing title on UIButton.
myButton.titleLabel?.font = UIFont(name: YourfontName, size: 20)
However, while setting title text you should only use setTitle:forControlState:. Do not use titleLabel to set any text for title directly.
For Swift 3.0:
button.titleLabel?.font = UIFont.boldSystemFont(ofSize: 16)
where "boldSystemFont" and "16" can be replaced with your custom font and size.
As mentioned by many here you can set the font with something like:
button.titleLabel?.font = .systemFont(ofSize: 19.0, weight: .bold)
Just make sure your button has default style though for this to be applicable, otherwise the above gets ignored by the system.
Dot-notation is awesome 👌
btn.titleLabel?.font = .systemFont(ofSize: 12)
If you need to change only size (Swift 4.0):
button.titleLabel?.font = button.titleLabel?.font.withSize(12)
You don't need to force unwrap the titleLabel to set it.
myButton.titleLabel?.font = UIFont(name: YourfontName, size: 20)
Since you're not using the titleLabel here, you can just optionally use it and if it's nil it will just be a no-op.
I'll also add as other people are saying, the font property is deprecated, and make sure to use setTitle:forControlState: when setting the title text.
In Swift 5, you can utilize dot notation for a bit quicker syntax:
myButton.titleLabel?.font = .systemFont(ofSize: 14, weight: .medium)
Otherwise, you'll use:
myButton.titleLabel?.font = UIFont.systemFont(ofSize: 14, weight: .medium)
From the documentation:
The font used to display text on the button. (Deprecated in iOS 3.0. Use the font property of the titleLabel instead.)
If you're having font size issues (your font isn't responding to size changes)...
#codester has the right code:
myButton.titleLabel!.font = UIFont(name: YourfontName, size: 20)
However, my font size wasn't changing. It turns out that I asking for a font that didn't exist ("HelveticaNeue-Regular"). It wasn't causing a crash, but seemed to be just ignoring that font statement because of it. Once I changed the font to something that does exist, changes to "size: x" did render.
we can use different types of system fonts like below
myButton.titleLabel?.font = UIFont.boldSystemFont(ofSize: 17)
myButton.titleLabel?.font = UIFont.italicSystemFont(ofSize:UIFont.smallSystemFontSize)
myButton.titleLabel?.font = UIFont.boldSystemFont(ofSize: UIFont.buttonFontSize)
and your custom font like below
myButton.titleLabel?.font = UIFont(name: "Helvetica", size:12)
Take a look here.
You should set the font of the button's titleLabel instead.
myButton.titleLabel!.font = UIFont(name: "...", 10)
If you are setting AttributedString to the UIButton then you can do the below thing.
let attributedText = NSAttributedString(string: "Hello", attributes: [NSAttributedStringKey.font: UIFont(name: "Calibri", size: 19)])
okayButton.setAttributedTitle(attributedText, for: .normal)
You should go through the titleLabel property.
button.titleLabel.font
The font property has been deprecated since iOS 3.0.
This works in Swift 3.0:
btn.titleLabel?.font = UIFont(name:"Times New Roman", size: 20)
Example: button.titleLabel?.font = UIFont(name: "HelveticaNeue-Bold", size: 12)
If you want to use defaul font from it's own family, use for example: "HelveticaNeue"
If you want to specify family font, use for example: "HelveticaNeue-Bold"
This way doesn't work now:
btn.titleLabel?.font = UIFont(name: "Helvetica", size:12)
This works:
btn.titleLabel?.font = UIFont.init(name: "Helvetica", size:12)
To do this using storyboard, go to the attributes inspector while your button is selected. In the third field from the top ("Title") select "Attributed". This will bring up the font drop-down list where you can easily change the font.
this work for me, thanks. I want change text size only not change font name.
var fontSizeButtonBig:Int = 30
btnMenu9.titleLabel?.font = .systemFont(ofSize: CGFloat(fontSizeButtonBig))
Swift 5
myButton.titleLabel?.font = UIFont(name: "yourCustomFont", size: CGFloat(yourFontSize))
