Question

I have a button in horizontal UITableView inside another UITableView. When I tap a button application crashes with this message “unrecognized selector sent to instance”. As I understand the problem is that another class handles tap but I don’t know how to fix it.

Answer 1

I have just solved. Maybe someone will need my solution.
I moved

[self.checkBoxButton addTarget:self action:@selector(checkBoxButtonAction) forControlEvents:UIControlEventTouchUpInside]; 

from view (actually this view is shown instead of cell

[cell addSubview:CellView.view];

)
to UITableView class to

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

and changed a little bit

[CellView.checkBoxButton addTarget:self action:@selector(checkBoxButtonAction) forControlEvents:UIControlEventTouchUpInside];

so, now tap handles not a view but uitableview class and everything works fine
