New features of the San Francisco font

Hi,

I suggest taking a look

UIFontDescriptor.

See this question on Stack Overflow http://stackoverflow.com/questions/21569861/how-to-stop-a-time-uilabel-from-resizing-at-every-time-increment

It's actually about fixed-width numbers, but the same technique applies to the kStylisticAlternativesType feature. You might want to do both.

It looks like the new forum doesn't handle screenshots, so here's a public dropbox link to some images that shows my iOS app ****** on iOS 9 with fixed-width numbers and the normal/alternate style for 6 and 9 digits: https://dl.dropboxusercontent.com/u/6668513/SanFransiconAlternateSixNine.zip

Hi Dirk,

thanks to your hint with UIFontDescriptor question number one has been settled. Regarding question number two: Is there a possibility to get the whole SF font monospaced and not just the digits? In the WWDC session, they said you can get monospaced numbers this way:

NSFont.monospacedDigitsSystemFontOfSize(mySize weight:)

But regrettably they didn't mention a way to get digits and letters monospaced ... Does anyone have a clue how to do that?

EDIT: To get monospaced letters and the alternate six and nine, I've already tried this:

NSArray *monospacedSetting = @[
@{UIFontFeatureTypeIdentifierKey:@(kStylisticAlternativesType), UIFontFeatureSelectorIdentifierKey: @(kStylisticAltOneOnSelector)}, 
@{UIFontFeatureTypeIdentifierKey:@(kTextSpacingType), UIFontFeatureSelectorIdentifierKey: @(kMonospacedTextSelector)}
];
UIFontDescriptor *newDescriptor = [[[UIFont fontWithName:@"SFUIText-Medium" size:12.8] fontDescriptor]
fontDescriptorByAddingAttributes:@{UIFontDescriptorFeatureSettingsAttribute:monospacedSetting}];

Regrettably, I just get the alternate six and nine and not the monospaced letters. Am I doing anything wrong or does kTextSpacingType: kMonospacedTextSelector not work on iOS 9 or rather with the SF font?

Kind regards,

Alex

The San Francisco font contains two sets of glyphs for numbers: one set that has proportional digits, and one set that has monospaced digits. (Many OpenType fonts have this feature.) But there are no glyphs in the font for letters and other characters which are designed to be monospaced. So kMonospacedTextSelector will not do anything.
