【Swift Mac开发】源代码创建NSTableView(含自定义NSTableViewCellView)

　　1、简易的tableView

//纯代码创建tableView，使用NSLayoutConstraint添加约束进行布局
import Cocoa

class JFSimpleTableViewController: NSViewController {

    var scrollView : NSScrollView!
    var tableView : NSTableView!
    
    override func viewDidLoad() {
        super.viewDidLoad()

        scrollView = NSScrollView(frame: self.view.bounds)
        self.view.addSubview(scrollView)
        
        tableView = NSTableView.init(frame: CGRect(x: 0, y: 0,  scrollView.bounds.size.width, height: scrollView.bounds.size.height))
        tableView.delegate = self
        tableView.dataSource = self
        
        let firstCol = NSTableColumn(identifier: NSUserInterfaceItemIdentifier(rawValue: "firstCol"))
        firstCol.width = 200
        firstCol.title = "第一列"
        tableView.addTableColumn(firstCol)
        
        let secondCol = NSTableColumn(identifier: NSUserInterfaceItemIdentifier(rawValue: "secondCol"))
        secondCol.width = scrollView.bounds.size.width - 200
        secondCol.title = "第二列"
        tableView.addTableColumn(secondCol)
        
        scrollView.documentView = tableView
    }

    override var representedObject: Any? {
        didSet {
        // Update the view, if already loaded.
        }
    }

}


extension JFSimpleTableViewController : NSTableViewDelegate,NSTableViewDataSource {
    
    func numberOfRows(in tableView: NSTableView) -> Int {
        return 10
    }
    
    func tableView(_ tableView: NSTableView, viewFor tableColumn: NSTableColumn?, row: Int) -> NSView? {
        let text = NSTextField()
        if tableColumn?.identifier == NSUserInterfaceItemIdentifier("firstCol") {
            text.stringValue = "(row)"
        } else {
            text.stringValue = "Hello World"
        }

        let cell = NSTableCellView()
        cell.addSubview(text)
        text.drawsBackground = false
        text.isBordered = false
        text.translatesAutoresizingMaskIntoConstraints = false

        //方法1：使用SnapKit进行布局
//        text.snp.makeConstraints { (make) in
//            make.centerY.equalTo(text)
//            make.left.equalTo(13)
//            make.right.equalTo(-13)
//        }
        
        //方法2：使用AutoLayout自布局
        cell.addConstraint(NSLayoutConstraint(item: text, attribute: .centerY, relatedBy: .equal, toItem: cell, attribute: .centerY, multiplier: 1, constant: 0))
        cell.addConstraint(NSLayoutConstraint(item: text, attribute: .left, relatedBy: .equal, toItem: cell, attribute: .left, multiplier: 1, constant: 13))
        cell.addConstraint(NSLayoutConstraint(item: text, attribute: .right, relatedBy: .equal, toItem: cell, attribute: .right, multiplier: 1, constant: -13))
        return cell
    }
    
    func tableView(_ tableView: NSTableView, rowViewForRow row: Int) -> NSTableRowView? {
        let rowView = NSTableRowView()
        rowView.isEmphasized = false
        return rowView
    }
}

　　2、自定义NSTableCellView

import Cocoa

class JFTableViewCell: NSTableCellView {

    var picImageView : NSImageView!
    var titleLab : NSTextField!

    override init(frame frameRect: NSRect) {
        super.init(frame: frameRect)
        configureView()
    }
    
    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
    override func draw(_ dirtyRect: NSRect) {
        super.draw(dirtyRect)

        // Drawing code here.
    }
    
    func configureView() {
        picImageView = NSImageView()
        picImageView.wantsLayer = true
        picImageView.layer?.backgroundColor = NSColor.red.cgColor
        self.addSubview(picImageView)
        
        titleLab = NSTextField()
        titleLab.textColor = NSColor.black
        titleLab.stringValue = "custom Cell"
        titleLab.drawsBackground = false
        titleLab.isBordered = false
        titleLab.translatesAutoresizingMaskIntoConstraints = false
        self.addSubview(titleLab)
        
        picImageView.snp.makeConstraints { (make) in
            make.left.equalTo(10)
            make.centerY.equalToSuperview()
            make.width.height.equalTo(30)
        }
        
        titleLab.snp.makeConstraints { (make) in
            make.left.equalTo(picImageView.snp.right).offset(10)
            make.centerY.equalTo(picImageView)
            make.height.equalTo(20)
            make.right.equalTo(-10)
        }
        
    }
    
}

import Cocoa
import SnapKit

class ViewController: NSViewController {

    var scrollView : NSScrollView!
    var tableView : NSTableView!
    
    override func viewDidLoad() {
        super.viewDidLoad()

        scrollView = NSScrollView(frame: self.view.bounds)
        self.view.addSubview(scrollView)
        
        tableView = NSTableView.init(frame: CGRect(x: 0, y: 0,  scrollView.bounds.size.width, height: scrollView.bounds.size.height))
        tableView.delegate = self
        tableView.dataSource = self

        
        let firstCol = NSTableColumn(identifier: NSUserInterfaceItemIdentifier(rawValue: "firstCol"))
        firstCol.width = 200
        firstCol.title = "第一列"
        tableView.addTableColumn(firstCol)
        
        let secondCol = NSTableColumn(identifier: NSUserInterfaceItemIdentifier(rawValue: "secondCol"))
        secondCol.width = scrollView.bounds.size.width - 200
        secondCol.title = "第二列"
        tableView.addTableColumn(secondCol)
        
        scrollView.documentView = tableView
    }

    override var representedObject: Any? {
        didSet {
        // Update the view, if already loaded.
        }
    }

}


extension ViewController : NSTableViewDelegate,NSTableViewDataSource {
    
    func numberOfRows(in tableView: NSTableView) -> Int {
        return 10
    }
    
    func tableView(_ tableView: NSTableView, viewFor tableColumn: NSTableColumn?, row: Int) -> NSView? {
        
        var frame = NSRect.zero
        if tableColumn?.identifier == NSUserInterfaceItemIdentifier("firstCol") {
            frame = NSRect(x: 0, y: 0,  200, height: 30)
        } else {
            frame = NSRect(x: 0, y: 0,  self.scrollView.bounds.width - 200, height: 30)
        }
        let cellView = JFTableViewCell(frame: frame)
        if tableColumn?.identifier == NSUserInterfaceItemIdentifier("firstCol") {
            cellView.titleLab.stringValue = "(row)"
        } else {
            cellView.titleLab.stringValue = "test"
        }
        
        return cellView
        
    }
    
    func tableView(_ tableView: NSTableView, rowViewForRow row: Int) -> NSTableRowView? {
        let rowView = NSTableRowView()
        rowView.isEmphasized = false
        return rowView
    }
}
