用SnapKit适配tableviewcell的自适应高度

iOS的时候经常用masnory进行适配，SnapKit是一个用Swift封装的autolayout自动适配的库，用法其实和masnory类似。

创建工程，用cocopods导入SnaoKit库

Podfile文件

platform :ios, '8.0'

use_frameworks!pod 'SnapKit'

在applicationdidFinishLaunchingWithOptions中加入如下代码

window =  UIWindow(frame: UIScreen.mainScreen().bounds)

window?.backgroundColor = UIColor.whiteColor()

window?.makeKeyAndVisible()

let vc:XLRootViewController = XLRootViewController()

let NVC:UINavigationController = UINavigationController(rootViewController: vc);

window?.rootViewController = NVC

viewdidload中代码

override func viewDidLoad() {

super.viewDidLoad()

self.CreateUI()

// Do any additional setup after loading the view.

}

func CreateUI() -> Void {

self.title = "自动布局"

let ChatTable:UITableView = UITableView(frame: CGRect(x: 0, y: 0, width: CGRectGetWidth(self.view.frame), height: CGRectGetHeight(self.view.frame)), style: UITableViewStyle.Plain)

self.view.addSubview(ChatTable)

ChatTable.delegate = self

ChatTable.dataSource = self

ChatTable.separatorStyle = UITableViewCellSeparatorStyle.None

ChatTable.registerClass(XLLeftCell().classForCoder, forCellReuseIdentifier:LeftCellIDF)

ChatTable.registerClass(XLRightCell().classForCoder, forCellReuseIdentifier: RightCellIDF)

// 设置大概高度

ChatTable.estimatedRowHeight = 80

// 设置行高为自动适配

ChatTable.rowHeight = UITableViewAutomaticDimension

}

自定义cell

现将子视图加入俯视图，在用SnapKit进行适配

self.contentView.addSubview(HeadImg!)

HeadImg?.snp_makeConstraints(closure: { (make) in

make.right.equalTo(self.contentView).offset(-15)

make.top.equalTo(self.contentView).offset(15)

make.width.equalTo(40)

make.height.equalTo(40)

})

let BacImgv:UIImageView = UIImageView.init()

BacImgv.image = IMG

self.contentView.addSubview(BacImgv)

BacImgv.snp_makeConstraints { (make) in

make.right.equalTo((HeadImg?.snp_left)!).offset(-20)

make.top.equalTo(self.contentView).offset(15)

make.bottom.equalTo(self.contentView).offset(-15)

make.width.lessThanOrEqualTo(200)

make.height.lessThanOrEqualTo(1000)

}

上面的代码中用lessThanOrEqualTo来对Label的父视图进行适配

在需要根据label上字数自适应高度的Label上这样适配

ContainLab.numberOfLines = 0

ContainLab.backgroundColor = UIColor.clearColor()

self.contentView.addSubview(ContainLab)

ContainLab.snp_makeConstraints(closure: { (make) in

make.edges.equalTo(BacImgv).inset(UIEdgeInsets.init(top: 20, left: 20, bottom: 20, right: 20))

})

效果图是这样
