swift4.0 TableView和自定义cell
原创文章，转载请获取本人同意
本文有snapkit三方布局的使用，类似于masonry，自己了解一下
另外用懒加载的方法添加了表头
一、tableView和协议实现

*本类主要实现tableview
*和使用snapkit自动布局

import UIKit
class MineViewController: UIViewController, UITableViewDataSource,UITableViewDelegate {
fileprivate var table:UITableView!
fileprivate var sendBtn:UIButton!
let arry:[String] = ["我是谁","我从哪里来","要到哪里去"]
override func viewDidLoad() {
super.viewDidLoad()
self.view.backgroundColor =UIColor.white
// Do any additional setup after loading the view.
self.title ="我的"
//设置UItabView的位置
table = UITableView()
self.view.addSubview(table)
//这个类似于masonry
table.snp.makeConstraints { (make)in
make.left.equalTo(self.view)
make.top.equalTo(self.view)
make.width.equalTo(CKWIDTH)
make.height.equalTo(350+64+100)
}
self.table.backgroundColor =UIColor.white
self.table.separatorStyle =UITableViewCellSeparatorStyle.none
//设置数据源
self.table.dataSource =self;
//设置代理
self.table.delegate =self;
self.table.register(UITableViewCell.classForCoder(), forCellReuseIdentifier:"cell")
table?.tableHeaderView =headerImage
sendBtn = UIButton()
sendBtn.setTitle("logout", for: .normal)
sendBtn.setTitleColor(UIColor.white, for: .normal)
sendBtn.titleLabel?.font =UIFont.systemFont(ofSize:14)
self.view .addSubview(sendBtn)
sendBtn.snp.makeConstraints { (make)in
make.centerX.equalTo(self.view)
make.top.equalTo(self.table.snp.bottom).offset(20)
make.width.equalTo(CKWIDTH*2/3)
make.height.equalTo(40)
}
sendBtn.backgroundColor =RGBA(r:32, g:169, b:242, a:1)
sendBtn.layer.cornerRadius =5
}
func numberOfSections(in tableView:UITableView) ->Int {
return 1
}
func tableView(_ tableView:UITableView, numberOfRowsInSection section:Int) ->Int {
return arry.count
}
func tableView(_ tableView:UITableView, cellForRowAt indexPath:IndexPath) ->UITableViewCell {
let indentifier = "MineCenterCell"
var cell:MineTableViewCell! = tableView.dequeueReusableCell(withIdentifier: indentifier)as?MineTableViewCell
if cell == nil {
cell = MineTableViewCell(style: .default, reuseIdentifier: indentifier)
}
cell.titleLabel?.text =self.arry[indexPath.row]
cell.linkLabel?.text =">"
return cell
}
//设置表头的高
func tableView(_ tableView:UITableView, heightForHeaderInSection section:Int) ->CGFloat {
return 200
}
func tableView(_ tableView:UITableView, heightForRowAt indexPath:IndexPath) ->CGFloat {
return 50
}
func tableView(_ tableView:UITableView, didSelectRowAt indexPath:IndexPath){
self.table.deselectRow(at: indexPathasIndexPath, animated:true)//点击完成，取消高亮
}
//懒加载
lazy var headerImage:UIImageView = {
let headerImage = UIImageView()
headerImage.setImageWith(nil, placeholder:UIImage(named:"cat"))
headerImage.frame = CGRect.init(x:0,y:0,width:CKWIDTH,height:200)
return headerImage
}()
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
/*
// MARK: - Navigation
// In a storyboard-based application, you will often want to do a little preparation before navigation
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
// Get the new view controller using segue.destinationViewController.
// Pass the selected object to the new view controller.
}
*/
}
二、自定义cell
//

// SwiftTest18-1-5

import UIKit
class MineTableViewCell: UITableViewCell {
var titleLabel:UILabel?
var linkLabel:UILabel?
var lineLabel:UILabel?
override init(style: UITableViewCellStyle, reuseIdentifier:String?) {
super.init(style: style, reuseIdentifier: reuseIdentifier)
self.titleLabel =UILabel()
self.contentView.addSubview(self.titleLabel!)
self.linkLabel =UILabel()
self.contentView.addSubview(self.linkLabel!)
self.lineLabel =UILabel()
self.contentView.addSubview(self.lineLabel!)
setupViews()
}
//刚开始会报错，后来加了一段这个东西
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
//这里来设置位置
func setupViews(){
//设置titleLabel
self.titleLabel?.snp.makeConstraints({ (make)in
make.centerY.equalTo(self)
make.left.equalTo(self).offset(20)
})
self.titleLabel?.font =UIFont.systemFont(ofSize:13)
//设置linkLabel
self.linkLabel?.snp.makeConstraints({ (make)in
make.centerY.equalTo(self)
make.right.equalTo(self).offset(-20)
})
self.linkLabel?.font =UIFont.systemFont(ofSize:13)
self.linkLabel?.text =">"
self.lineLabel?.snp.makeConstraints({ (make)in
make.left.equalTo(self).offset(20)
make.right.equalTo(self).offset(-20)
make.bottom.equalTo(self).offset(-1)
make.height.equalTo(1)
})
self.lineLabel?.backgroundColor =RGBA(r:242, g:242, b: 242, a: 1)
}
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override func layoutSubviews() {
super.layoutSubviews()
setupViews()
}
override func setSelected(_ selected: Bool, animated:Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
}
