Before Starting I want to make sure one thing whether we can make the ViewController transparent (alpha), as far my knowledge it is NO.

I have a ViewController which consists of 8 UIButton objects over it. Whenever I press Button1, Button2 I am loading a ViewController. Since the ViewController cannot be made transparent, I just moved that View to my HomeViewController.xib and I am loading the view using -addSubView:. And I am changing the alpha value to make it as transparent.

But the thing is in Button1 View and Button2 View, in both views I am having table view. When I bring everything to the same HomeViewController class , I am having too much of code in a single class.

Is there any way to do this?? Adding many Views in the same ViewController not a problem, but it increases the code too. Which looks ugly. Please help me out.

If I have confused about my question here I am giving a short description of what I would like to do
Whenever I press a Button in ViewController, I want to load a View/ViewController Transparently.

    Before Starting I want to make sure one thing whether we can make the
    ViewController transparent (alpha), as far my knowledge it is NO.

    You can’t adjust a view controllers alpha directly. You can adjust a view controllers view properties alpha, ex: myViewController.view.alpha, and you can do this for any view that you want except for your root view (the bottom of the view stack). Lowering your root views alpha would allow the user to see the springboard through your app.

    But the thing is , In Button1 View and Button2 View , in both views I
    am having table view. When I bring everything to the same
    HomeViewController class , I am having too much of code in a single
    class.
    Is there any way to do this ?? Adding Many Views in the same
    ViewController not a problem, but it increases the code too. Which

    I’m not sure I understand the problem here. As long as you format your code correctly and keep well organized this isn’t a problem. I personally have used view controllers in excess of 15k lines of code and never had a problem, and I’m sure there are developers that have used way more.

    If I have confused about my question here I am giving a short
    description of what I would like to do Whenever I press a Button in
    ViewController , I want to load a View/ViewController Transparently.

    Continue the way you have been describing. (adding alpha adjusted UIView‘s as subviews) There is nothing wrong with this approach.
