# CHGAdapter 
主要解决UITableView 在每个controller中都需要设置dataSource和delegate的烦恼，并UITableViewCell与DataSource tableView解耦合
具体表现为

- Adapter与UITableView、Adapter与UITableViewCell完全解耦合。
- 只需要在controller中设置好adapter，给adapter需要显示的数据，adapter会把每个cell需要的数据赋予cell。
- UITableViewCell中按钮的点击事件、UITextField的输入事件、UISwitch等等都通过统一的CHGTableViewDidSelectRowBlock进行传输。
- controller少了很多有关UITableViewDelegate以及UITableViewDatasource的相关代码，controller代码更加清晰。
- 基于以上特点adapter、cell、HeaderFooterView都可以最大限度的复用

### Installation with CocoaPods

> pod 'CHGAdapter', '~> 1.1.5'
- 导入头文件 #import "CHGAdapter.h"

### example （UITableView）
以下Demo为swift代码所写，但是和OC版本没有任何区别

- 1.显示cell

```
import UIKit

/// 展示TableView中只有cell的用法
class Base1ViewController: UIViewController {

@IBOutlet weak var tableView: UITableView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        title = "歌曲"
        tableView.cellDatas = [getSongs()!]
    }

func getSongs() -> [Any]? {
        var songs = [Any]()
        for item in ["七里香","青花瓷","简单爱","双截棍","夜曲","以父之名","稻香","可爱女人","红尘客栈","床边故事","跨时代"] {
            songs.append(SongsModel(name: item))
        }
        return songs
        
    }
}

```

- 2.显示header和footer

```
import UIKit

/// 展示TableView中存在headerFooterView和cell的用法
class Base2ViewController: UIViewController {

@IBOutlet weak var tableView: UITableView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        title = "展示TableView中存在headerFooterView和cell的用法"
        tableView.headerDatas = getHeaderModels()
        tableView.cellDatas = [getSongs1(),getSongs2()]
        tableView.footerDatas = getFooterModels()
    }
    
    ///专辑1数据
    func getSongs1() -> [Any] {
        var songs = [Any]()
        for item in ["半兽人","半岛铁盒","暗号","龙拳","火车叨位去","分裂（离开）","爷爷泡的茶","回到过去","米兰的小铁匠","最后的战役"] {
            songs.append(SongsModel(name: item))
        }
        return songs
    }
    
    ///专辑2数据
    func getSongs2() -> [Any] {
        var songs = [Any]()
        for item in ["爱在西元前","爸我回来了","简单爱","忍者","开不了口","上海一九四三","对不起","威廉古堡","双截棍","安静"] {
            songs.append(SongsModel(name: item))
        }
        return songs
    }
    
    ///headerView数据
    func getHeaderModels() -> [Any]? {
        return [Album.init(name: "八度空间", createTime: "2002年7月18日"),
                Album.init(name: "范特西", createTime: "2001年9月20日")]
    }
    
    ///footerView数据
    func getFooterModels() -> [Any]? {
        return [AlbumDesc.init(desc: "《八度空间》这张专辑的创作灵感来自周杰伦平时看的一些电影和音乐录影带。"),
                AlbumDesc.init(desc: "《范特西》的专辑名称来源是英文“Fantasy”的发音，意为范特西范特西(3张)“幻想” 。")]
    }

}

```

- 3.cell点击处理

```
import UIKit

class Base3ViewController: UIViewController {

@IBOutlet weak var tableView: UITableView!
    override func viewDidLoad() {
        super.viewDidLoad()
        title = "基础3（cell点击处理）"
        tableView.cellDatas = [getSongs()]
        
        tableView.setTableViewDidSelectRowBlock { (tableView, indexPath, itemData) in
            guard let model:SongsModel = itemData as? SongsModel else { return }
            print("当前点击：\(model.name!)")
        }
    }

func getSongs() -> [Any] {
        var songs = [Any]()
        for item in ["七里香","青花瓷","简单爱","双截棍","夜曲","以父之名","稻香","可爱女人","红尘客栈","床边故事","跨时代"] {
            songs.append(SongsModel(name: item))
        }
        return songs
        
    }
}

```

### example （UICollectionView）用法和UICollectionView完全一样

- 1.显示cell

```
import UIKit

class Base1ViewController: UIViewController {

@IBOutlet weak var collectionView: UICollectionView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        title = "歌曲"
        collectionView.cellDatas = [getSongs()!]
    }

```

- 2.显示header和footer

```
import UIKit

/// 展示collectionView中存在headerFooterView和cell的用法
class Base2ViewController: UIViewController {

@IBOutlet weak var collectionView: UICollectionView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        title = "展示collectionView中存在headerFooterView和cell的用法"
        collectionView.headerDatas = getHeaderModels()
        collectionView.cellDatas = [getSongs1(),getSongs2()]
        collectionView.footerDatas = getFooterModels()
    }
    
    ///专辑1数据
    func getSongs1() -> [Any] {
        var songs = [Any]()
        for item in ["半兽人","半岛铁盒","暗号","龙拳","火车叨位去","分裂（离开）","爷爷泡的茶","回到过去","米兰的小铁匠","最后的战役"] {
            songs.append(SongsModel(name: item))
        }
        return songs
    }
    
    ///专辑2数据
    func getSongs2() -> [Any] {
        var songs = [Any]()
        for item in ["爱在西元前","爸我回来了","简单爱","忍者","开不了口","上海一九四三","对不起","威廉古堡","双截棍","安静"] {
            songs.append(SongsModel(name: item))
        }
        return songs
    }
    
    ///headerView数据
    func getHeaderModels() -> [Any]? {
        return [Album.init(name: "八度空间", createTime: "2002年7月18日"),
                Album.init(name: "范特西", createTime: "2001年9月20日")]
    }
    
    ///footerView数据
    func getFooterModels() -> [Any]? {
        return [AlbumDesc.init(desc: "《八度空间》这张专辑的创作灵感来自周杰伦平时看的一些电影和音乐录影带。"),
                AlbumDesc.init(desc: "《范特西》的专辑名称来源是英文“Fantasy”的发音，意为范特西范特西(3张)“幻想” 。")]
