A simple jump show sub Controller for Addchildviewcontroller

The use of Addchildviewcontroller can save memory effectively, and can easily display the sub-controller you want to display, the following is a simple implementation of Swift jump process.

Class first : uiviewcontroller {

//two,three, four for three controllers respectively

var : Both ?

var three: three?

var four : three?

//child Test

var addchildvcclick: UIButton?

var currentc: uiviewcontroller?

override func viewdidload () {

Super. Viewdidload()

self. View. BackgroundColor = uicolor. Bluecolor()

self. Setupsubview()

}

func Setupsubview () {

Addchildvcclick = UIButton()

self. View. Addsubview(addchildvcclick!)

Addchildvcclick?. frame = cgrectmake(Max, +, +)

Addchildvcclick?. backgroundcolor = uicolor. Greencolor()

Addchildvcclick?. userinteractionenabled = true

Addchildvcclick?. addTarget(self, action: "AddChild", forControlEvents:. TouchDown)

}

// Click the button to implement the child controller add

func addChild () {

Print("Add Child")

both = ()

self. Addchildviewcontroller(both!)

three = three()

self. Addchildviewcontroller(three!)

Four = three()

four!. View. BackgroundColor = uicolor. Browncolor()

self. Addchildviewcontroller(four!)

The Child controller is only displayed if the view of the sub-controller is added

self. View. Addsubview(four!). view)

if let f = four {

// Add a button to the fourth Controller and click to implement the Sub controller switch

Addchildvcclick?. frame = cgrectmake(Max, +, +)

Addchildvcclick?. backgroundcolor = uicolor. Bluecolor()

Addchildvcclick?. userinteractionenabled = true

Addchildvcclick?. addTarget(self, action: "Changeviewcontroller", forControlEvents:. TouchDown)

F.view. Addsubview(addchildvcclick!)

CurrentC = f // must be set Currenc(Global properties)

}

}

func Changeviewcontroller () {

Print("Changeviewcontroller")

a. View. BackgroundColor = uicolor. Redcolor()

self. Transitionfromviewcontroller(CurrentC!, Toviewcontroller: both!, Duration: 1, Options:. Transitioncurlup, animations: {(), Void in

Print("animations")

}) {(COM), Void in

Print("com")

self. CurrentC = self. a real jump here, simple and convenient

the// jump effect is determined by the options parameter

}

}

}
