In an iOS app I have a ViewController that has a ContainerView in which a ViewController (say VC2) resides, using an Embed Segue. This VC2 owns a UITableView and it's datasource and delegate are set to the VC2 and also conforms to the UITableViewDataSource and UITableViewDelegate protocols. Now the cells are rendered perfectly, so the dataSource seems good. But when I try to select a row, nothing happens, so there seems to be a problem with the delegate. However, the delegate methods willDisplayCell and shouldHightlightRowAt do get called. And I only implemented these method to check whether the delegate is set up correctly. And no, I did NOT implement the didDeselectRowAt method, which is a common mistake.
In IB the tableview owns two dynamic prototype cells, the Selection property is set to Single Selection and the Style is set to Plain. Both the UITableViewCells have a Style set to Custom and Selection is set to Default.
Why doesn't the didSelectRowAt method get called? I did check the isEditing property, which is set to false; editing is not relevant in my case.
this is my didSelect method:
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
print("didSelectRowAt (indexPath.row)")
}
I use Swift 4.
I'm sorry, but it seems that Xcode has given me a really hard time. I just deleted the ViewController from the storyboard and built it up from scratch again. Also created a new file for the VC and now everything works just as expected. Sometimes the is the way to go is delete all your work and start over again and in this particular case... it was.
I really cannot say what could be the cause; but it seems that something got messed up in the storyboard file. At least, that is my best guess.
Wasted some time... Thanks anyway for attending...
