For the More Curious: NSFontManager

Sometimes, you will find a font that is good but would be perfect if it were bold or italicized or condensed. NSFontManager can be used to make this sort of conversion. You can also use a font manager to change the size of the font.

For example, imagine that you have a font and would like a similar font but bold. Here is the code:

l​e​t​ ​f​o​n​t​M​a​n​a​g​e​r​ ​=​ ​N​S​F​o​n​t​M​a​n​a​g​e​r​.​s​h​a​r​e​d​F​o​n​t​M​a​n​a​g​e​r​(​)​
l​e​t​ ​b​o​l​d​F​o​n​t​ ​=​ ​f​o​n​t​M​a​n​a​g​e​r​.​c​o​n​v​e​r​t​F​o​n​t​(​s​o​m​e​F​o​n​t​,​
 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​t​o​H​a​v​e​T​r​a​i​t​:​ ​N​S​F​o​n​t​T​r​a​i​t​M​a​s​k​.​B​o​l​d​F​o​n​t​M​a​s​k​)​
