swift3.0 代码创建经典界面的九宫图--优化篇

在上一篇只是简单实现了九宫图效果，本章需要形成APP界面九宫图效果

override func viewDidLoad() {

super.viewDidLoad()

createnine()

}

／／九宫图算法

func createnine(){

／／高

let kAppViewH:CGFloat=80

／／宽

let kAppViewW:CGFloat=80

／／行个数

let kColCount:Int=3

／／间隔

let kStart:Int=20

let MarginX:CGFloat=(self.view.frame.size.width-CGFloat(kColCount)*kAppViewW)/CGFloat(kColCount+1)

let MarginY:CGFloat=10

for i in 0 ..< 12 {

let row:Int=i/kColCount;

let col:Int=i%kColCount;

let colF:CGFloat=CGFloat(col);

let x=MarginX+CGFloat(col)*(kAppViewW+MarginX);

let y=CGFloat(kStart)+MarginY+CGFloat(row)*(kAppViewH+MarginY);

var imageView=UIImageView(image: UIImage(named: ""))

imageView.frame=CGRect(x: 0, y: 0, width: 60, height: 60)

／／增加Lable

var nameLabel=UILabel(frame: CGRect(x:0, y: 60, width: Int(kAppViewW), height: 20))

nameLabel.text="功能"

nameLabel.textAlignment=NSTextAlignment.center

nameLabel.backgroundColor=UIColor.blue

//var btnBuuton=UIButton.button

／／增加按钮

let btnButton=UIButton(frame: CGRect(x: 0, y: 20, width: 60, height: 60))

btnButton.tag=i

btnButton.setTitle("按钮", for: UIControlState.normal)

btnButton.addTarget(self, action: #selector(btnClick(sender:)), for:

.touchUpInside)

let view=UIView(frame: CGRect(x: x, y: y, width: kAppViewW, height: kAppViewH))

view.backgroundColor=UIColor.red

view.addSubview(imageView)

view.addSubview(nameLabel)

view.addSubview(btnButton)

//加入视图

self.view.addSubview(view)

}

效果如下
