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
