There are many places in the picture stretching application, so don't give an example! The following is a personal opinion, if there is a wrong place, please give me a lot of advice!

There are two ways to use:

First, using the Stretchableimagewithleftcapwidth method, set the point leftcapwidth and Topcapheight of the Extrude

Code:

Set image Image Stretch

var image = UIImage (named: "TextTag")

Let Leftcapwidth:int = Int (IMAGE.SIZE.WIDTH/2)//Take the center point of the picture width

Let Topcapheight:int = Int (IMAGE.SIZE.HEIGHT/2)//Take the center point of the picture height

Image = Image.stretchableimagewithleftcapwidth (leftcapwidth, topcapheight:topcapheight)//Stretch

Imageview.image = Image

Second, using the Resizableimagewithcapinsets method, set the non-stretched margin uiedgeinsetsmake

Code:

　　Let ImageView = Uiimageview (Frame:cgrectmake (40, 40, 300, 30))

Let image = UIImage (named: "Testtag")?. Resizableimagewithcapinsets (uiedgeinsetsmake (0, 0, +), ResizingMode:UIImageResizingMode.Stretch)

Imageview.image = Image

View.addsubview (ImageView)
