According to the WWDC presentation "Introducing the New System Fonts", the SF font has an option to display numbers as monospaced. I would like to use this option in several places in my iOS 9 app. In OS X it is apparently possible via NSFont.monospacedDigitSystemFontOfSize, but I did not find similar option in UIFont.
Can anybody point me to the right direction?
Ok, I figured this one out.
func systemFontWithMonospacedNumbers(size: CGFloat) -> UIFont {
let features = [
[
UIFontFeatureTypeIdentifierKey: kNumberSpacingType,
UIFontFeatureSelectorIdentifierKey: kMonospacedNumbersSelector
]
]
let fontDescriptor = UIFont.systemFontOfSize(size).fontDescriptor().fontDescriptorByAddingAttributes(
[UIFontDescriptorFeatureSettingsAttribute: features]
)
return UIFont(descriptor: fontDescriptor, size: size)
}Ok, I figured this one out.
func systemFontWithMonospacedNumbers(size: CGFloat) -> UIFont {
let features = [
[
UIFontFeatureTypeIdentifierKey: kNumberSpacingType,
UIFontFeatureSelectorIdentifierKey: kMonospacedNumbersSelector
]
]
let fontDescriptor = UIFont.systemFontOfSize(size).fontDescriptor().fontDescriptorByAddingAttributes(
[UIFontDescriptorFeatureSettingsAttribute: features]
)
return UIFont(descriptor: fontDescriptor, size: size)
}Swift 3 / XCode 9 update:
func systemFontWithMonospacedNumbers(size: CGFloat) -> UIFont {
let features = [
[
UIFontDescriptor.FeatureKey.featureIdentifier: kNumberSpacingType,
UIFontDescriptor.FeatureKey.typeIdentifier: kMonospacedNumbersSelector
]
]
let fontDescriptor = UIFont.systemFont(ofSize: size).fontDescriptor.addingAttributes(
[UIFontDescriptor.AttributeName.featureSettings: features]
)
return UIFont(descriptor: fontDescriptor, size: size)
}
