快速地，在didSelectRowAt之前调用prepare

Question

I'm trying to build a tableview in swift, when a cell is tapped, another view which contains the details of that cell will appear. I used prepare method to send an object to the second view to show the details. However, when I tapped a cell, the second view will show information about the previously tapped cell. I used the didSelectRowAt to catch the current tapped cell, and used the prepare method to send the object. Is there any chance I can use one of these two methods perform this task correctly?

Any hints would be most appreciated.

Answer 1

Keep the segue defined, but do not connect it to selecting a row. Instead, you can (for example):

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    self.performSegueWithIdentifier("mySegueIdentifier", sender: tableView)
}

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject!) {
    if segue.identifier == "mySegueIdentifier" {
        // do your normal stuff here....
    }
}

Answer 2

step1: connect the whole table to the view

step2: call below function in didSelectedRow
