I think it's already too late, but for anyone who has the same question, there are two solutions to change the font of the application without specifying the font size .:
The first is a workaround that iterates through all the shortcuts of your UIView and changing the font of the labels, check this question and answers: How to set a custom font for the entire iOS application without specifying a size .
The second creates a category for your management:
@implementation UILabel (MyCustomLabel) -(void)awakeFromNib{ float fontSize = [self.font pointSize]; self.font = [UIFont fontWithName:@"MyCustomFont" size:fontSize]; } @end
