iOS TableView wrong indexPath when selecting cell with keyboard shown

Question

I have tableView size set by AutoLayout (bottom to Bottom Layout Guide, top to another view and so on but first UISearchBar to Top Layout Guide):

Controller with tableView:

I need to change table offset when keyboard is shown so I have these two methods:

// MARK: - Keyboard
func keyboardWasShown (notification: NSNotification) {
    let info: NSDictionary = notification.userInfo!
    let value: NSValue = info.valueForKey(UIKeyboardFrameBeginUserInfoKey) as! NSValue
    let keyboardSize: CGSize = value.CGRectValue().size

    self.tableView.contentInset = UIEdgeInsetsMake(0, 0, keyboardSize.height, 0)
    self.tableView.scrollIndicatorInsets = self.tableView.contentInset

}

func keyboardWillBeHidden (notification: NSNotification) {
    self.tableView.contentInset = UIEdgeInsetsZero
    self.tableView.scrollIndicatorInsets = UIEdgeInsetsZero
}

And it's working but I have problem when keyboard is shown. The last item can't be selected and instead of that I get previous item. I tapped where is last item and it should navigate to detail page with last item but instead I see detail page with previous item. It isn't shift for all items but just for the last one and when I filtered to just one item it's working okay. When keyboard is hidden (and items are still filtered) then It's okay too (it selects the right thing). So I guess the problem must be here:

    self.tableView.contentInset = UIEdgeInsetsMake(0, 0, keyboardSize.height, 0)
    self.tableView.scrollIndicatorInsets = self.tableView.contentInset

So where could be problem? Thanks for help

Answer 1

I got my solution. I was using UIKeyboardWillHideNotification and method keyboardWillBeHidden was called before didSelectRowAtIndexPath so contentInset of tableView was set back to UIEdgeInsetsZero and then there was wrong indexPath. So now I use keyboardDidHide instead of keyboardWillBeHidden:

    NSNotificationCenter.defaultCenter().addObserver(self, selector: "keyboardWasShown:", name: UIKeyboardDidShowNotification, object: nil)
    NSNotificationCenter.defaultCenter().addObserver(self, selector: "keyboardWillBeHidden:", name: UIKeyboardWillHideNotification, object: nil)
    NSNotificationCenter.defaultCenter().addObserver(self, selector: "keyboardDidHide:", name: UIKeyboardDidHideNotification, object: nil)

...

func keyboardDidHide (notification: NSNotification) {     
    self.tableView.contentInset = UIEdgeInsetsZero
    self.tableView.scrollIndicatorInsets = UIEdgeInsetsZero
}
