Swift Gaussian blur for custom view

var bgimage = Uiimageview ()

var Backbutton = UIButton ()

var Titlelabel = UILabel ()

Let Screen_h = UIScreen.main.bounds.height

Let Screen_w = UIScreen.main.bounds.width

Override Init (Frame:cgrect) {

First create a Blur effect

Let Blureffect = Uiblureffect (style:. Dark)

Then create a view that hosts the Blur effect

Let Blurview = Uivisualeffectview (effect:blureffect)

Set the size of the blur view (full screen)

BlurView.frame.size = Cgsize (Width:screen_w, height:64)

Add Blur view to Page view (Blur appears underneath the Blur view)

blurview.alpha=0.7

Self.addsubview (Blurview)

Backbutton = UIButton (type:. Custom)

Backbutton.frame = CGRect (x:0, y:20, width:60, height:44)

Backbutton.backgroundcolor = Uicolor.clear

Backbutton.setimage (UIImage (named: "Btn_return"), for:. Normal)

Self.addsubview (Backbutton)

Titlelabel.frame=cgrect (X:SCREEN_W/2-100,Y:20+44/2-8,WIDTH:200,HEIGHT:18)

Titlelabel.text= "Old Glass"

Titlelabel.textcolor=uicolor.white

titlelabel.textalignment =. Center

Titlelabel.font = Uifont (name: "Arial", size:16.0)

Self.addsubview (Titlelabel)

}
