OC转swift3.0实践 (一)最基础的UI
2016-12-02 本文已影响1031人
APP叫我取个帅气的昵称
之前的搭框架啥的基本与OC没啥区别,但有种情况,就是要建个桥文件
,来使swift项目中可以引用pods
导入的OC的第三方库,想知道具体怎么建的可在下面评论留言。
进入正题,今天要做的是99%的APP要有的个人中心页面,用的是系统自带的cell
。效果图如下
ps:如何建桥文件已经在另一篇OC转swift3.0实战 (二)使用自定义cell的tableview中写明。
这个页面很简单,整体一个
tabview
,里面有一个headerView
,加5个section
。由于是刚开始实战,这里不用xib
而是用纯代码来建头部(说到这,不禁有一个问题,是xib
开发好呢还是纯代码好呢?)新建一个
view
继承自UIView
language
选用swift,完成。接下来不用像OC那样重写init,直接干。代码如下:
import UIKit
class ZLMMineHeaderView: UIView {
//懒加载
///背景视图
lazy var backImageView:UIImageView = {[weak self](result)in
let img = UIImageView(image:#imageLiteral(resourceName: "bannerBackground"))
img.contentMode = .scaleAspectFill
img.layer.masksToBounds = true
self?.addSubview(img)
return img
}()
///背景图上方的一层蒙版
// lazy var alphaView:UIView = {[unowned self]in
// let view = UIView()
// view.backgroundColor = UIColor.hexInt(0x000000)
// view.alpha = 0.3
// self.addSubview(view)
// return view
// }()
///设置按钮
lazy var settingBtn:UIButton = {[weak self](result)in
let btn = UIButton(type:.custom)
btn.setImage(#imageLiteral(resourceName: "setting"), for: .normal)
self?.addSubview(btn)
return btn
}()
///头像视图
lazy var avatarImageView:UIImageView = {[weak self](result)in
let img = UIImageView(image:#imageLiteral(resourceName: "unlogin"))
img.layer.masksToBounds = true
img.layer.cornerRadius = 45.0
img.layer.rasterizationScale = UIScreen.main.scale
img.layer.shouldRasterize = true
self?.addSubview(img)
return img
}()
///登录/注册
lazy var loginBtn:UIButton = {[weak self](result)in
let btn = UIButton(type: .custom)
btn.setTitle("登录/注册", for: .normal)
btn.setTitleColor(UIColor.white, for: .normal)
self?.addSubview(btn)
return btn
}()
override func layoutSubviews() {
super.layoutSubviews()
//背景视图
backImageView.frame = CGRect(x:0,y:0,width:ScreenW,height:200)
// alphaView.frame = backImageView.frame
settingBtn.frame = CGRect(x:ScreenW-40,y:35,width:30,height:30)
avatarImageView.frame = CGRect(x:ScreenW/2-45,y:55,width:90,height:90)
loginBtn.frame = CGRect(x:ScreenW/2-45,y:145,width:90,height:30)
}
}
自定义的View解决了 接下来就是controller里的事了。ps:这个页面的数据都是写死的,没涉及到网络层。代码如下:
import UIKit
let headerViewH:CGFloat = 200
class ZLMMainViewController: UIViewController {
//普通属性
var lightFlag:Bool = true
//懒加载
///tableview
lazy var tableView: UITableView = {[weak self](result) in
let tableView = UITableView(frame:CGRect(x:0, y:0, width:ScreenW, height:(self?.view.frame.height)!),style:.grouped)
tableView.delegate = self
tableView.dataSource = self
tableView.backgroundColor = BACKGROUND_Color
self?.view.addSubview(tableView)
return tableView
}()
///列表标题数组
lazy var titleArray:[[String]] = {
return[["我的订单"],["我的会员卡","我的收藏","我的收货地址",],["我的优惠券"],["IC卡查询"],["帮助中心"]]
}()
///列表图标数组
lazy var imageArray:[[UIImage]] = {
return [[#imageLiteral(resourceName: "order")],[#imageLiteral(resourceName: "memberCard"),#imageLiteral(resourceName: "favorite"),#imageLiteral(resourceName: "address")],[#imageLiteral(resourceName: "coupon")],[#imageLiteral(resourceName: "score")],[#imageLiteral(resourceName: "help")]]
}()
///头部视图
lazy var headerView:ZLMMineHeaderView = {
let view = ZLMMineHeaderView(frame:CGRect(x:0,y:0,width:ScreenW,height:headerViewH))
return view
}()
///状态栏
lazy var statusBackView:UIView = {[weak self](result)in
let view = UIView(frame:CGRect(x:0,y:0,width:ScreenW,height:20))
view.backgroundColor = UIColor.white.withAlphaComponent(0.95)
self?.view.addSubview(view)
self?.view.bringSubview(toFront:view)
return view
}()
//生命周期
override func viewDidLoad() {
super.viewDidLoad()
view.backgroundColor = UIColor.hexInt(0xf3f3f3)
automaticallyAdjustsScrollViewInsets = false
setupView()
// Do any additional setup after loading the view.
}
///设置状态栏样式
override var preferredStatusBarStyle: UIStatusBarStyle{
if lightFlag {
return .lightContent
}else{
return .default
}
}
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
navigationController?.setNavigationBarHidden(true, animated: true)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
//初始化
extension ZLMMainViewController{
///初始化视图
fileprivate func setupView(){
tableView.tableHeaderView = UIView(frame:CGRect(x:0,y:0,width:ScreenW,height:headerViewH))
tableView.addSubview(headerView)
}
}
//UITableview代理 &&数据源
extension ZLMMainViewController:UITableViewDelegate,UITableViewDataSource{
func numberOfSections(in tableView: UITableView) -> Int {
return titleArray.count
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
let subTitleArr = titleArray[section]
return subTitleArr.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let subTextArr = titleArray[indexPath.section]
let imgArr = imageArray[indexPath.section]
let cellID = "cellId"
var cell = tableView.dequeueReusableCell(withIdentifier: cellID)
if cell == nil {
cell = UITableViewCell(style: .default,reuseIdentifier:cellID)
}
cell?.textLabel?.text = subTextArr[indexPath.row]
cell?.textLabel?.font = UIFont.systemFont(ofSize: 14)
cell?.textLabel?.textColor = RGBA(r:0.0,g:0.0,b:0.0,a:1.0)
cell?.accessoryType = .disclosureIndicator
cell?.selectionStyle = .none
cell?.imageView?.image = imgArr[indexPath.row]
return cell!
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
return
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 44.0
}
func tableView(_ tableView: UITableView, heightForFooterInSection section: Int) -> CGFloat {
return 10.0
}
func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
return 0.1
}
}
这样这个页面的UI就搭好了,里面的点击事件都没实现,跳转和OC也没多大区别。同样,有啥问题可以留言哦。
