1, Appdelegate

(1) define variable var Blockrotation:bool = False

(2) Definition method

Swift Code

Func application (application:uiapplication, Supportedinterfaceorientationsforwindow Window:uiwindow?) Uiinterfaceorientationmask {
If self.blockrotation{
Return Uiinterfaceorientationmask.all
} else {
Return uiinterfaceorientationmask.portrait
}
}

2, to horizontal screen of the Viewcontroller

(1) Get variables

Let appdelegate = Uiapplication.sharedapplication (). Delegate as! Appdelegate

(2) Modify the value of the blockrotation variable in viewdidload

　　override func Viewdidload () {

Super. Viewdidload ()      

appdelegate.blockrotation = true        

}

(3) Viewwillappear Setting page Horizontal screen

Override func Viewwillappear (Animated:bool) {

Let value = UIInterfaceOrientation.LandscapeLeft.rawValue

Uidevice.currentdevice (). SetValue (Value, Forkey: "Orientation")

}

(4) Viewwilldisappear Settings page back to vertical screen

Override func Viewwilldisappear (Animated:bool) {

Appdelegate.blockrotation = False

Let value = UIInterfaceOrientation.Portrait.rawValue

Uidevice.currentdevice (). SetValue (Value, Forkey: "Orientation")

}

(5) Whether the horizontal screen page supports rotation

Whether to support automatic horizontal screen. See item adjustable, can be set to True

Override Func Shouldautorotate (), Bool {

return False

}

Experience Summary:

The above situation is an interface vertical screen to jump to the second horizontal screen interface.

Need an interface can vertical screen, and then want to vertical screen player that suddenly a horizontal screen, how to do, the next step is to enlarge the Recruit:

Call the following action for the desired horizontal or vertical screen.

MARK:- Horizontal screen

func hengp () {

appdelegate. Blockrotation = true

let value = uiinterfaceorientation. Landscapeleft. RawValue

uidevice. Currentdevice(). SetValue(value, Forkey: "Orientation")

}

//MARK:- vertical screen

func shup () {

appdelegate. Blockrotation = false

let value = uiinterfaceorientation. Portrait. RawValue

uidevice. Currentdevice(). SetValue(value, Forkey: "Orientation")

}

The agent is triggered when a rotation is about to occur

Override func willrotatetointerfaceorientation (tointerfaceorientation: uiinterfaceorientation , Duration: nstimeinterval) {

}

The rotation is complete to trigger the proxy. We need to re-layout the necessary interface settings here

override func didrotatefrominterfaceorientation (frominterfaceorientation: Uiinterfaceorientation) {

Gets the screen mode of the current phone's physical state to see whether it is a horizontal or vertical screen.

let interfaceorientation = uiapplication. Sharedapplication(). Statusbarorientation

if(interfaceorientation = = uiinterfaceorientation. Portrait)

{

// current is in vertical screen mode

Print(" vertical screen ")

}Else{

// current is in the horizontal screen mode

self. Thewebview?. frame = self. View. Frame

}

}

Remember: After the horizontal screen, and the vertical screen before the width of the value is changed, if you have a cache to save the width of the value, in this case, after the horizontal screen to obtain the previous vertical screen of the saved width of the value, must be re-obtained,

Let bwidth = cgrectgetwidth(uiscreen. Mainscreen(). Bounds) ///< screen width

let bheight = cgrectgetheight(uiscreen. Mainscreen(). Bounds) ///< screen height
