Swift 实现QQ好友列表功能

整理了一下实现QQ好友列表的功能，数据也是自己手动拼接模拟的
QQFriend 存储好友数据信息

class QQFriend: NSObject {

var name: String?

var intro: String?

init(dic: NSDictionary) {

super.init()

self.setValuesForKeys(dic as! [String : AnyObject])

}

}

QQFriendGroup 存储好友分组数据

class QQFriendGroup: NSObject {

var name: String?

var friends: NSArray?

var isOpen: Bool? = false

init(withDic dic: NSDictionary) {

super.init()

self.setValuesForKeys(dic as! [String : AnyObject])

let arrayFriend: NSMutableArray = NSMutableArray()

for friendDic in self.friends! {

let friend : QQFriend = QQFriend.init(dic: friendDic as! NSDictionary)

arrayFriend.add(friend)

}

self.friends = arrayFriend

}

}

QQHeaderView 分组View

//协议

protocol QQHeaderViewDelegate: NSObjectProtocol {

func headerViewDidClickedNameLab(headerView:QQHeaderView)

}

class QQHeaderView: UITableViewHeaderFooterView {

weak var delegate:QQHeaderViewDelegate?

var nameLabel: UILabel? = {

let nameLabel = UILabel()

return nameLabel

}()

var arrow: UIImageView? = {

let arrow = UIImageView.init(image: UIImage(named: "orderDown"))

return arrow

}()

var group: QQFriendGroup? {

didSet {

self.nameLabel?.text = group?.name

didMoveToSuperview()

}

}

var clickNameBlock: ((Void)->())? = nil

var dividerView : UIView! = nil

class func headerViewWithTableView(tableview: UITableView) -> QQHeaderView {

let headerID = "myHeader"

var header = tableview.dequeueReusableHeaderFooterView(withIdentifier: headerID)

if header == nil {

header = QQHeaderView.init(reuseIdentifier: headerID)

}

return header as! QQHeaderView

}

override init(reuseIdentifier: String?) {

super.init(reuseIdentifier: reuseIdentifier)

let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(QQHeaderView.nameClick))

self.nameLabel?.isUserInteractionEnabled = true

self.arrow?.isUserInteractionEnabled = true

self.contentView.addGestureRecognizer(tap)

self.contentView.addSubview(nameLabel!)

self.contentView.addSubview(arrow!)

let divideView = UIFactory.create_AView()

divideView.backgroundColor = UIColor.hrgb("cccccc")

self.contentView.addSubview(divideView)

self.dividerView = divideView

}

required init?(coder aDecoder: NSCoder) {

fatalError("init(coder:) has not been implemented")

}

//点击展开或收起列表

func nameClick() {

self.group?.isOpen = !(self.group?.isOpen)!

//        if ((self.delegate?.responds(to: Selector(("headerViewDidClickedNameLab:")))) != nil) {

//            self.delegate?.headerViewDidClickedNameLab(headerView: self)

//        }

if self.clickNameBlock != nil {

self.clickNameBlock!()

}

}

override func didMoveToSuperview() {

super.didMoveToSuperview()

if self.group?.isOpen == true {

self.arrow?.transform = CGAffineTransform.init(rotationAngle: .pi)

}else {

self.arrow?.transform = CGAffineTransform.init(rotationAngle: 0)

}

}

override func layoutSubviews() {

super.layoutSubviews()

self.nameLabel?.snp.makeConstraints({ (make) in

make.left.equalTo(15)

make.top.equalTo(0)

make.bottom.equalTo(0)

make.right.equalTo(-30)

})

self.arrow?.snp.makeConstraints({ (make) in

make.right.equalTo(-10)

make.width.height.equalTo(14)

make.centerY.equalTo(self.height * 0.5)

})

self.dividerView.snp.makeConstraints { (make) in

make.height.equalTo(0.5)

make.left.right.bottom.equalTo(0)

}

}

}

ImitationQQ 控制器 实现功能

extension ImitationQQ {

func numberOfSections(in tableView: UITableView) -> Int {

return (self.groups?.count)!

}

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

let group: QQFriendGroup = self.groups![section] as! QQFriendGroup

return group.isOpen == true ? group.friends!.count : 0

}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

let cell : UITableViewCell = tableView.dequeueReusableCell(withIdentifier: "default", for: indexPath)

cell.textLabel?.text = "\(indexPath.section)" + "\(indexPath.row)"

cell.selectionStyle = .none

return cell

}

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {

return 40

}

func tableView(_ tableView: UITableView, heightForFooterInSection section: Int) -> CGFloat {

return 0.01

}

func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {

let header: QQHeaderView = QQHeaderView.headerViewWithTableView(tableview: tableView)

header.delegate = self

header.clickNameBlock = {

self.tabView.reloadData()

}

header.group = self.groups![section] as? QQFriendGroup

return header

}

func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {

return 44

}

}

extension ImitationQQ {

func headerViewDidClickedNameLab(headerView: QQHeaderView) {

self.tabView.reloadData()

}

}

class ImitationQQ: UIViewController, UITableViewDataSource, UITableViewDelegate, QQHeaderViewDelegate {

var tabView: UITableView! = nil

var dividerView : UIView! = nil

lazy var groups : NSArray? = {

var arr : NSMutableArray = NSMutableArray()

for i in 0..<3 {

let group: QQFriendGroup = QQFriendGroup.init(withDic: ["name":"\(i)" + "组", "friends":[["name":"00","intro":"挺好的"],["name":"01","intro":"挺好好的"],["name":"02","intro":"挺好好好的"],["name":"03","intro":"挺好好好好的"]]] as NSDictionary)

arr.add(group)

}

return arr

}()

override func viewDidLoad() {

super.viewDidLoad()

self.view.backgroundColor = UIColor.hrgb("f4f4f4")

self.title = "好友列表"

let tabView = UIFactory.create_ATableView(frame: CGRect.init(x: 0, y: 0.5, width: Screen_Width, height: kScreenHeight-64.5), delegate: self, dataSource: self, superView: self.view, type: .plain)

tabView.backgroundColor = UIColor.hrgb("f4f4f4")

tabView.register(UITableViewCell.self, forCellReuseIdentifier: "default")

self.tabView = tabView

let divideView = UIFactory.create_AView()

divideView.frame = CGRect(x: 0, y: 0, width: Screen_Width, height: 0.5)

divideView.backgroundColor = UIColor.hrgb("cccccc")

self.view.addSubview(divideView)

self.dividerView = divideView

}

}

不太会排版，这么贴代码好low，下次改进一下。
