How to navigate to viewController from tableview cell, which is placed in other tableview Cell? - ios

Question

I have placed a tableview2 in tableview1 Cell, Now when I click on the tableview2 cell I need to navigate to a new viewController. Please help me... I was struggling with one whole day :(
here is the code, the second table view is placed in SegmentedCell...
when i am trying to push, its unable to go next controller..

Answer 1

I have created a similar scenario as yours and this is how you can get it working.
1. View Hierarchy
I have used tag property to uniquely identify both UITableViews, i.e.
Outer tableView tag = 0
Inner tableView tag = 1
2. Now implement UITableViewDataSource, UITableViewDelegate methods for both the tableViews. Set the dataSource and delegate of both the tableViews as the ViewController.
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
if tableView.tag == 0
{
return 1
}
else if tableView.tag == 1
{
return 5
}
return 0
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
if tableView.tag == 0
{
return tableView.dequeueReusableCell(withIdentifier: "outercell", for: indexPath)
}
else if tableView.tag == 1
{
return tableView.dequeueReusableCell(withIdentifier: "innercell", for: indexPath)
}
return UITableViewCell()
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath)
{
if tableView.tag == 1
{
//TODO: Write your code for navigating to another ViewController here
print("Inner cell tapped")
}
}
Edit:
In the Interface Builder, you can find a tag attribute corresponding to each element in the attributes inspector, i.e.
For outer tableView set it to 0 and for inner tableView set it to 1.
Let me know if you still face any issues. Happy Coding..🙂

Answer 2

Use performSegue(withIdentifier: "ViewController", sender: self); in didSelectrow method of you tableView2.
