Question

Is there a way I can change the System Font for an entire Application?

I want to define the font for the entire Application so that I don’t have to go to individual labels or individual fonts to change it. I would like a universal definition which will change all the fonts that exist within the application. How do I do this?

Answer 1

Make a shared class called Constants.h or something. In it do this:

#define kStandardFont [UIFont systemFontOfSize:20] 

Of course adjust the font to be what you need it to be. Then, whenever you need to use it (in a label or whatever) do this:

#import "Constants.h"
…
…
… 
[label setFont:kStandardFont];
