New changes in iOS9 programming Gogogo:xcode7

Do a demo about Stack view Uistackview, first look at the changes of XCode7

About Storyboard:

Start screen changed from Xib to storyboard

Storyboard References:
It is now possible to add a reference to another storyboard in a storyboard, switching between multiple SB without having to write the code again.

The way it used to be (SWIFT):

override func viewDidLoad() {        super.viewDidLoad()        var sb : UIStoryboard        let del = UIApplication.sharedApplication().delegate as! AppDelegate        "LaunchScreen", bundle: nil)        del.window?.rootViewController = sb.instantiateInitialViewController()    }

Now drag the corresponding action directly to the storyboard reference you want to jump to

About Stack Views:
1. Drag and drop some controls out:

2. Select the controls and click the New button to the left of the Autolayoutbutton group. stack!

3. They are grouped into a vertical stack view (p.s. Stack view can only be selected horizontally or vertically two)

4. Change the view axis of the stack. Change to a level to see the effect:

5. So that the spacing between the controls does not come out, we change the distribution properties. Change from fill to equal spacing, and then to a value of 20, the control itself actively at a distance of 20 to hash the entire stack view

6. It is also possible to unify the alignment, for example the vertical stack. Uniform left-aligned. Effect:

7. Create a socket for this stack view to see how to manipulate its sub-views with code:

8. Get its child view returns an array of sequential views through the Arrangedsubview property:

9. Take the 1 subscript of this array. So that's the slider, change his value to 0.9. Then the execution will slide to 90% places:
