Change font size on traitCollectionDidChange

I am attempting to work around the stupid Apple 'no custom fonts with auto-layout' bug but I am ruing into issues implementing it in a way that will also work with trait collection updates.

I originally was ruing the code on a 0.5 delay from a delay-called function on viewDidLoad and in there it was updating the font size and font type correctly for the device. However I leaed that traitCollectionDidChange is also called during that time so I moved my code into there instead. Now the font type is not updating but the font size is updating.

Here is my code, it is probably something stupid I am overlooking:

- (void)traitCollectionDidChange:(UITraitCollection *)previousTraitCollection{
    //[super traitCollectionDidChange: previousTraitCollection];
    //Create horz/vert vars for easier iffing
    UIUserInterfaceSizeClass viewHorizontal = self.view.traitCollection.horizontalSizeClass;
    UIUserInterfaceSizeClass viewVertical = self.view.traitCollection.verticalSizeClass;

    //Change font and font size depending on classes; really just the size but we need to set the font anyway
    if (viewHorizontal == UIUserInterfaceSizeClassCompact && viewVertical == UIUserInterfaceSizeClassCompact){
        agTtl_Text.font = [UIFont fontWithName:@"Hobo Std" size:36];
        agSubttl_Text.font = [UIFont fontWithName:@"Hobo Std" size:20];
        actBtn.titleLabel.font = [UIFont fontWithName:@"Hobo Std" size:20];
        nAccBtn.titleLabel.font = [UIFont fontWithName:@"Hobo Std" size:20];
    } else if (viewHorizontal == UIUserInterfaceSizeClassCompact && viewVertical == UIUserInterfaceSizeClassRegular){
        agTtl_Text.editable = YES; //still need this iOS 6 hack?
        agTtl_Text.font = [UIFont fontWithName:@"Hobo Std" size:35];
        agSubttl_Text.font = [UIFont fontWithName:@"Hobo Std" size:20];
        actBtn.titleLabel.font = [UIFont fontWithName:@"Hobo Std" size:30];
        nAccBtn.titleLabel.font = [UIFont fontWithName:@"Hobo Std" size:30];

        agTtl_Text.editable = NO; //still need this iOS 6 hack?
    }
}
