编辑tableView时，自定义单元格imageView移到左侧

Question

I have a tableView that I need to be able to delete items from, however, when I put it back from editing mode, the imageView from my custom cell gets shifted over to the left side. Here's some relevant code and images:

 func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    var cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! NotificationsTableViewCell
    cell.storiesLabel.text = stories[indexPath.row].name
    cell.selectionStyle = UITableViewCellSelectionStyle.None
    cell.shouldIndentWhileEditing = false

    if stories[indexPath.row].notificationBool == true {
        cell.notificationImageView.image = UIImage(named: "notifications_filled.png")
    }
    else {
        cell.notificationImageView.image = UIImage(named: "notifications.png")
    }

    return cell
}

func editFollowedStoriesTableView() {
    if tableView.editing == true {
        tableView.setEditing(false, animated: false)
    }
    else {
        tableView.setEditing(true, animated: false)
    }
}

 func tableView(tableView: UITableView, editingStyleForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCellEditingStyle {

    if(self.tableView.editing){

        return UITableViewCellEditingStyle.Delete

    }
    return UITableViewCellEditingStyle.None

}

How can I prevent the second picture from happening? Any help is very much appriciated!

Answer 1

You have some conflicting auto layout constraints. You need to delete one of the following constraints on the UIImageView:

Width
Leading Space to: Label
Trailing space to: Superview

Here, The leading space and trailing space constraints define the width of the imageView. Then you added the width constraint that does the same thing. Now if you want your image view to have a fixed width delete either the leading space or trailing space constraint. If you don't need to have a fixed width, delete the width constraint.
