Ios-uiview operation (SWift)

1. Gradient fill of the UIView view

Override Func Viewdidload () {

Super.viewdidload ()

Additional setup after loading the view, typically from a nib.

Drawing of gradient fill color

Let rect = CGRect (x:30, y:60, width:200, height:200)

Let Gradientview = UIView (frame:rect)

Let Gradientlayer = Cagradientlayer ()

Gradientlayer.frame = Gradientview.frame

Let Fromcolor = Uicolor.yellowcolor (). Cgcolor

Let Midcolor = Uicolor.redcolor (). Cgcolor

Let Tocolor = Uicolor.purplecolor (). Cgcolor

Gradientlayer.colors = [Fromcolor,midcolor,tocolor]

Adds a set of gradient layers to the layer of the View object.

View.layer.addSublayer (Gradientlayer)

Adds a view object to the root view of the current View controller

Self.view.addSubview (Gradientview)

}

2. Textures for UIView views

Override Func Viewdidload () {

Super.viewdidload ()

Additional setup after loading the view, typically from a nib.

Tile the entire screen with imported pictures as textures

Let image = UIImage (named: "Sample")

Creates a new color object, assigns the imported picture to the object

Let PatternColor = Uicolor.init (patternimage:image!)

Self.view.backgroundColor = PatternColor

}
