I want to set label text as System Thin. Read in StackOverflow and found an answer like this:
labelDescriptionView.font = UIFont(name: "System-Thin", size: 15.0)
but it did not work. How can I improve my code and make Thin font style programmatically?
The system
font in the Interface Builder is the OS default font, it is not a font you can get by it's name. For the system font Apple provides the following methods:
+ (UIFont *)systemFontOfSize:(CGFloat)fontSize;
+ (UIFont *)boldSystemFontOfSize:(CGFloat)fontSize;
+ (UIFont *)italicSystemFontOfSize:(CGFloat)fontSize;
These do not include any thin version but iOS 8.2 onwards you can use:
+ (UIFont *)systemFontOfSize:(CGFloat)fontSize weight:(CGFloat)weight;
Where you can pass: as weights:
UIFontWeightUltraLight
UIFontWeightThin
UIFontWeightLight
UIFontWeightRegular
UIFontWeightMedium
UIFontWeightSemibold
UIFontWeightBold
UIFontWeightHeavy
So a thin system font would be:
UIFont *thinFont = [UIFont systemFontOfSize:15 weight:UIFontWeightThin];
