计数函数在 Swift 2 中不起作用

Question

嗨，我是 swift 和 ios 的新手，这里有一个问题。我从 segementedController 调用了 3 个不同的 table 视图。

一切正常，但每次我按分段控制器上的任何选项卡时，它都会打印星期一。只统计了table1.

的数据

@IBOutlet weak var d1 : UITableView!
@IBOutlet weak var d2 : UITableView!
@IBOutlet weak var d3 : UITableView!
@IBOutlet weak var segementedControlAction: UISegmentedControl!


var Names = ["Name1", "Name2","Name3","Name4"]
var Images =  ["1.jpg","2.jpg","5.jpg","8.jpg"]
var set =  ["14","15","16","17"]

var Names1 = ["Name5", "Name6","Name7"]
var Images1 =  ["6.jpg","4.jpg","7.jpg"]
var set1 =  ["4","5","6"]

var Names2 = ["Name9", "Name12","Name13","Name14"]
var Images2 =  ["11.jpg","21.jpg","51.jpg","81.jpg"]
var set2 =  ["114","115","116","117"]


func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
var count: Int = 0
tableView.layer.cornerRadius = 10
tableView.layer.masksToBounds = true

if (tableView == self.d1) {
    print("Monday")
    count = self.Names.count
}
else if (tableView == self.d2) {
    print("Tuesday")
    count = self.Names1.count
}
else if (tableView == self.d3) {
    print("Wednesday")
    count = self.Names2.count
}

return count
}


func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) ->
UITableViewCell {

let cellIdentifier = "Cell"
let cell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier, forIndexPath:
    indexPath) as! CustomTableViewCell

if segementedControlAction.selectedSegmentIndex == 0 {
cell.nameLabel.text = Names[indexPath.row]
cell.thumbnailImageView.image = UIImage(named: Images[indexPath.row])
cell.setLabel.text = set[indexPath.row]

}

else if segementedControlAction.selectedSegmentIndex == 1 {

cell.nameLabel.text = Names1[indexPath.row]
cell.thumbnailImageView.image = UIImage(named: Images1[indexPath.row])
cell.setLabel.text = set1[indexPath.row]
}


else {segementedControlAction.selectedSegmentIndex == 2

cell.nameLabel.text = Names2[indexPath.row]
cell.thumbnailImageView.image = UIImage(named: Images2[indexPath.row])
cell.setLabel.text = set2[indexPath.row]

}

return cell }

编辑：每当 select 分段控制器的第二个选项卡

时应用程序崩溃

Answer 1

也许你可以简化一下

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return tableView.count
}

Answer 2

试试这个

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

tableView.layer.cornerRadius = 10
tableView.layer.masksToBounds = true

    if segementedControlAction.selectedSegmentIndex == 0 {

        print("Monday")

        return self.Names.count 
    }

   else if segementedControlAction.selectedSegmentIndex == 1 {

        print("Tuesday")

            return self.Names1.count

    }
     else if segementedControlAction.selectedSegmentIndex == 2 { 
       print("Wednesday")

        return self.Names2.count

    }
}

计数函数在 Swift 2 中不起作用

Count function is not working in Swift 2
