1，下面是一个利用UIView来给页面上绘制灰色方块的例子，效果图如下：

import
UIKit
class
ViewController
:
UIViewController
{
//游戏方格维度
var
dimension:
Int
= 4
//数字格子的宽度
width:
CGFloat
= 50
//格子与格子的间距
padding:

//保存背景图数据

2，进阶版 - 继承UIView实现自定义方块组件（有颜色和数字）
方块组件：TileView.swift
TileView
{
//颜色映射表，不同的数字颜色不同
let
colorMap = [
2:
.redColor(),
4:
.orangeColor(),
8:
.yellowColor(),
16:
.greenColor(),
32:
.brownColor(),
64:
.blueColor(),
128:
.purpleColor(),
256:
.cyanColor(),
512:
.lightGrayColor(),
1024:
.magentaColor(),
2048:
.blackColor()
]
//在设置值时，更新视图的背景和文字
value:
= 0{
didSet
{
backgroundColor = colorMap[value]
numberLabel.text=
"\(value)"
}
}
numberLabel:
UILabel
!
//初始化视图
init
(pos:
CGPoint
,width:
)
{
numberLabel =
(0,width))
numberLabel.textColor =
.whiteColor()
numberLabel.textAlignment =
NSTextAlignment
.
Center
numberLabel.minimumScaleFactor = 0.5
numberLabel.font =
UIFont
(name:
"微软雅黑"
numberLabel.text =
"\(value)"
.
(pos.x,pos.y,monospace!important; min-height:inherit!important">addSubview(numberLabel)
.value = value
backgroundColor = colorMap[value]
}
(coder : aDecoder)
}
|
使用：
| //数字格子的宽度
= 50
//格子与格子的间距
= 6
//保存背景图数据
>!
viewDidLoad()
{
.viewDidLoad()
>()
//改成主视图背景白色背景
.whiteColor()
setupGameMap()
}
setupGameMap()
{
= 50
= 150
0..<dimension
{
(i)
y = 150
0..<dimension
{
//随机2的1～11次方
val:
= 2<<
(arc4random_uniform(10))
(x:x,y:y),width:
.width,value: val)
.view.addSubview(background)
//将视图保存起来，以备后用
backgrounds.append(background)
y += padding + width
}
x += padding+width
}
didReceiveMemoryWarning() {
.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
