My app uses only system fonts, and I am creating them with function - 

+ (UIFont * _Nonnull)systemFontOfSize:(CGFloat)fontSize weight:(CGFloat)weight

How Can I make System font Italic with weight UIFontWeightThin?

I cannot use the call for specific family font (fontWithName:) since I want it to be system fonts only.

Thanks :)

  • I don't want to use UIFont fontWithName: since I want it to be the System font (Helvetica for ios 8, SF for ios 9 etc.) – Talia Segev Nov 02 '15 at 12:39

You should create Font Descriptor at first that contain the type of your font if it Italic or Bold or Thin, etc..

UIFontDescriptor* desc = [UIFontDescriptor fontDescriptorWithFontAttributes:
                          @{
                            UIFontDescriptorFaceAttribute: @"Thin"
                            }
                          ];

after that create a font object that hold the descriptor information

UIFont *font = [UIFont fontWithDescriptor:desc size:17];

So, set you font object to your label.

Now you got a font object using system font but you can change the the type and size of it without using fontWithName.

  • But how would you make a font with both "Thin" and "Italic" face attributes? You can't have duplicate keys in the dictionary. – Dielson Sales Jun 30 '16 at 12:52
  • @DielsonSales you can create two UIFontDescription objects, one for 'thin' and one for 'italic', and now you can create your font using whatever you want, even italic or thin. – Islam.Ibrahim Jun 30 '16 at 13:31

What about something like this:

[youLabel setFont:[UIFont fontWithName:[youLabel.font fontName] size:UIFontWeightThin]];

  • Size is not the same thing as weight. You should not pass `UIFontWeightThin`, but should pass the size of the text to the setFont:size: method. – Kekoa May 12 '16 at 13:51
