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
