ios - Presenting a ViewController over another ViewController -

I have found a very long question today, because it explains something, starting with an example.

---

Example

Suppose I have three view controllers:

1. Full Size Week Controller
2. FirstViewController < Second view controller

Full size week controller, as the name states, is targeted to replace the entire screen. On the other hand, the first view controller and second view controller , Only about 3/4 of the height of the screen should be taken For example here are some pictures.

Here we have FullSizeViewController No, just two buttons - "first" & amp; "second". If you have not already captured it, then those two buttons should toggle each of the related view controllers, as shown below.

problem

< P> Do I have main issues with this?

1. Animate the controllers below
2. Change the size of two small view controllers
3. Still allow contact with FullSizeViewController Also a small view controller is open on top of its main content but does not have two toggle buttons?

what have I tried

Since I'm also not sure how to do this, I have not tried so much, but I got one thing Have tried.

In the IBAction, the "first" button is attached:

  Let's first: first Wii Controller = Self Storyboard. Instantiet UIU Controller with Identifier ("FirstviewConverter")! FirstViewController as self.PresentViewController (firstVC, animated: true, perfection: zero)  

FirstViewController in viewDidLoad:

  self.view.frame. Size = CGSizeMake (UIScreen.mainScreen (). Bounds.isize.width, UIScreen.mainScreen (). Bounds.size.height - 68)
