我正在处理一个项目，以更改当段值更改时由表视图显示的array.实现这一目标的最简单方法是什么？谢谢!
@IBAction func segmentValueChanged(_ sender: UISegmentedControl) {
if sender == testSwitcher {
if testSwitcher.selectedSegmentIndex == 0 {
print("Hello World")
}
else if testSwitcher.selectedSegmentIndex == 1 {
print("Data Update")
newArray = []
stateElections.data = newArray
stateElections.reloadData()
}
您可以实现如下所示的内容
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{
let myCell = tableView.dequeueReusableCellWithIdentifier("myCell", forIndexPath: indexPath)
switch(mySegmentedControl.selectedSegmentIndex)
{
case 0:
myCell.textLabel!.text = arrayList1[indexPath.row]
break
case 1:
myCell.textLabel!.text = arrayList2[indexPath.row]
break
case 2:
myCell.textLabel!.text = arrayList3[indexPath.row]
break
default:
break
}
return myCell
}
@IBAction func segmentedControlActionChanged(sender: AnyObject) {
myTableView.reloadData()
}
