UI updates

[MeteC]

Hey there, I've made some changes for my own purposes that might be of interest in the main project.

1. Made it more obj-c friendly by adding @objc access to various customisable properties.
2. Buttons on the action sheet now automatically highlight on touch.
3. Item interval spacing is customisable per action sheet.
4. You can define a default font for the whole CustomizableActionSheetItem class to set app-wide font settings simply.

Thanks for using and enhancing!

I reply per items what you listed.

1. Made it more obj-c friendly by adding @objc access to various customisable properties.

I think to should not adding @objc. Because of keeping as pure swift.
In current, it’s not problem to add @objc , but it may be disturb if we wanna use new feature of Swift in future.

2. Buttons on the action sheet now automatically highlight on touch.

It’s nice feature.
But coding style is not equal with existing codes.
Please fix it.
(Ex. “There is no self.” “First variable name what start with _”)

3. Item interval spacing is customisable per action sheet.

This is nice feature too.

4. You can define a default font for the whole CustomizableActionSheetItem class to set app-wide font settings simply.

Currently, this needs is satisfied by subclassing {CustomizableActionSheetItem.
So I think it should be not merged to keep interface simpler.

Make private this extension because of there is risk conflict with library user

This property can be simpler by below.

public var backgroundColor: UIColor = UIColor.white {
  didSet {
    if let highlightColor = color.darkerColor() {
      self.backgroundHighlightColor = highlightColor
    }
  }
}

Do not use force unwrap.
Force unwrap is very dangerous except @IBOutlet .

thanks @beryu - I'll take a look at that! :-)

Have made changes as requested, see what you think!

In summary:

1. Buttons on action sheet now automatically highlight on touch
2. Item interval spacing is customisable per action sheet.
3. (new) Items can have upperMargin value set, which adds spacing at the top of the item. This is so you can for example have a Cancel button at the bottom slightly apart from the rest of the buttons.

Code style reviewed, extra @objc access removed, static default fonts removed.
