How to programmatically select a row in UITableView in Swift

Question

I need to select a row in a UITableView programmatically using Swift 1.2.

This is the simple code:

var index = NSIndexPath(forRow: 0, inSection: 0)
         


        

Answer 1

Using Swift 2.x, as described by Pankaj purohit answers the correct method is:

func tapRowAtIndex(index:Int) {
        let rowToSelect:NSIndexPath = NSIndexPath(forRow: index, inSection: 0)
        self.tableView.selectRowAtIndexPath(rowToSelect, animated: true, scrollPosition: UITableViewScrollPosition.None)
        self.tableView(self.tableView, didSelectRowAtIndexPath: rowToSelect)
}

Keep in mind that if you call this method from an external class for example, you dont know when tableView has finished its loading, so what's the possibilities?, how to workaround this problem? :

Step one: create a class boolean var

var automatingTap: Bool = false

Step two: check when the table finish its loading and launch an "end operations" method:

func tableView(tableView: UITableView, didEndDisplayingCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath) 
{
    let lastRowIndex = tableView.numberOfRowsInSection(0)
    if indexPath.row == lastRowIndex - 1 {
       endOperations()
    }
}

func endOperations() 
{
   print("finished loading")
   if automatingTap {
        tapRowAtIndex(0)
        automatingTap = false
   }
}

Step three: call my tableView class from another class

for example:

override func prepareForSegue(segue: UIStoryboardSegue?, sender: AnyObject?) {
    if segue!.identifier == "DetailsTableView" {
        let viewController:ViewController = segue!.destinationViewController as ViewController
        viewController.automatingTap = true
    }
}
