Is it possible to edit UIAlertAction title font size and style?

Now that iOS8 deprecated UIActionsheet and UIAlertview the customization working on iOS7 is not taking effect anymore. So far the only customization I’m aware is the tint color. And what I need is changing the title’s font size and style which I haven’t found any way of doing so with the new UIAlertAction.

Already referred to this but I’m still hoping there’s a way to change at least the title size and font.

    You can change UIAlertAction’s Font and color.
    First you need to add UILabel Category

    @interface UILabel (FontAppearance)
    @property (nonatomic, copy) UIFont * appearanceFont UI_APPEARANCE_SELECTOR;
    @end
    
    @implementation UILabel (FontAppearance)
    
    -(void)setAppearanceFont:(UIFont *)font {
        if (font)
            [self setFont:font];
    }
    
    -(UIFont *)appearanceFont {
        return self.font;
    }
    
    @end

    It is possible to change alert action’s font using private APIs. It may get you app rejected, I have not yet tried to submit such code.

    let alert = UIAlertController(title: nil, message: nil, preferredStyle: .ActionSheet)
    
    let action = UIAlertAction(title: "Some title", style: .Default, handler: nil)let attributedText = NSMutableAttributedString(string: "Some title")
    
    let range = NSRange(location: 0, length: attributedText.length)
    attributedText.addAttribute(NSKernAttributeName, value: 1.5, range: range)
    attributedText.addAttribute(NSFontAttributeName, value: UIFont(name: "ProximaNova-Semibold", size: 20.0)!, range: range)
    
    alert.addAction(action)
    
    presentViewController(alert, animated: true, completion: nil)
    
    // this has to be set after presenting the alert, otherwise the internal property __representer is nil
    guard let label = action.valueForKey("__representer")?.valueForKey("label") as? UILabel else { return }
    label.attributedText = attributedText
