How to set a custom font for entire iOS app without specifying size

Question

I'm trying to apply a custom font throughout my iOS app. I found that I could use:

 [[UILabel appearance] setFont:[UIFont fontWithName:@"Proxima Nova" size:17.0]]; 

• To set the default font and size for all UILabels. However, not all my UILabels share the same font size.

• In Set a default font for whole iOS app?, someone had the same concern, and was told to set the size parameter to 0.0 to only set the font and not font size.

• When I tried doing this, all the UILabel text in my app disappeared (because evidently iOS took the 0.0 font size literally).

Any suggestions as to how I can universally set a font but not size? Thanks a lot!

- (void)viewDidLoad {     [super viewDidLoad];     [self setFontFamily:@"FagoOfficeSans-Regular" forView:self.view andSubViews:YES]; }  -(void)setFontFamily:(NSString*)fontFamily forView:(UIView*)view andSubViews:(BOOL)isSubViews {     if ([view isKindOfClass:[UILabel class]])     {         UILabel *lbl = (UILabel *)view;         [lbl setFont:[UIFont fontWithName:fontFamily size:[[lbl font] pointSize]]];     }      if (isSubViews)     {         for (UIView *sview in view.subviews)         {             [self setFontFamily:fontFamily forView:sview andSubViews:YES];         }     }     }
