Programmatically UITableView using swift

Question

I\'m trying to create a simple tableView programmatically using swift, so I wrote this code on \"AppDelegate.swift\" :

    func application(application: UIA         


        

Answer 1

It is as simple as writing a function

    func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell!
{
    let cell: UITableViewCell = UITableViewCell(style: UITableViewCellStyle.Subtitle, reuseIdentifier: "MyTestCell")

    cell.text = self.Myarray[indexPath.row]
    cell.textLabel.textColor = UIColor.greenColor()

    cell.detailTextLabel.text = "DummyData #\(indexPath.row)"
    cell.detailTextLabel.textColor = UIColor.redColor()
    cell.imageView.image = UIImage(named:"123.png")
    return cell
}

In Xcode 6 Beta 4

Removing

init(style: UITableViewStyle) {
    super.init(style: style)
}

will do the trick. This is caused by different initializer behavior between Obj-C and Swift. You have created a designated initializer. If you remove it, all initializers will be inherited.

The root cause is probably in -[UITableViewController initWithStyle:] which calls

[self initWithNibName:bundle:]

I actually think this might be a bug in the way Obj-C classes are converted to Swift classes.

Cell Function Use:

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

    var cell = tableView.dequeueReusableCellWithIdentifier(kLCellIdentifier) as UITableViewCell!
    if !cell {
        cell = UITableViewCell(style:.Default, reuseIdentifier: kLCellIdentifier)
    }
    cell.backgroundColor = UIColor.clearColor()
    cell.textLabel.text = arrData[indexPath.row]
    cell.image = UIImage(named: "\(arrImage[indexPath.row])")   
    cell.accessoryType  = UITableViewCellAccessoryType.DetailDisclosureButton
    cell.selectionStyle = UITableViewCellSelectionStyle.None
    return cell
}

Answer 4

Instead of

init(style: UITableViewStyle) {
    super.init(style: style)
}

you might find this handy:

convenience init() {
    self.init(style: .Plain)
    title = "Plain Table"
}

Then, you can just call TableViewController() to initialize.
