[英]Tableview controller how to add edit button to rearrange the rows IOS Swift 2
請在下面找到代碼,我需要在tableviewcontroller視圖頂部的編輯按鈕,該按鈕可以重新排列或刪除行。 任何幫助將不勝感激。 我找到了一個內置函數來刪除單個行,但是我特別需要一個編輯按鈕。
import UIKit
class TableViewController: UITableViewController {
var sports:[Sport] = []
override func viewDidLoad() {
loadData()
super.viewDidLoad()
// Uncomment the following line to preserve selection between presentations
// self.clearsSelectionOnViewWillAppear = false
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem()
}
func loadData(){
if let path = NSBundle.mainBundle().pathForResource("data", ofType: "plist"){
if let tempDict = NSDictionary(contentsOfFile: path){
let tempArray = (tempDict.valueForKey("sports") as! NSArray) as Array
for dict in tempArray {
let sportName = dict["sportName"]! as! String
let numberOfPlayers = dict["numberOfPlayers"]! as! String
let countryOfOrigin = dict["countryOfOrigin"]! as! String
let p = Sport(sportName: sportName, numberOfPlayers:numberOfPlayers, countryOfOrigin:countryOfOrigin)
sports.append(p)
}
}
}
}

生成的代碼包含以下注釋:
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem()
取消注釋第二行:
self.navigationItem.rightBarButtonItem = self.editButtonItem()
您可能還需要實現一些其他委托函數才能使該功能正常工作:
override func tableView(tableView: UITableView, canEditRowAtIndexPath indexPath: NSIndexPath) -> Bool
override func tableView(tableView: UITableView, moveRowAtIndexPath fromIndexPath: NSIndexPath, toIndexPath: NSIndexPath)
override func tableView(tableView: UITableView, canMoveRowAtIndexPath indexPath: NSIndexPath) -> Bool
例如,除非您實施適當的委托方法,否則單擊/按住以重新排序項目右側的小條將不可用。
