pass data from UITableCell to UITabView

I am currently working on a project that requires a list of customers to be displayed in a UITableView, the associated cell then segues to a TabView to display a detailed customer record in a tabbed ui.

I have setup the story board with the required TableView and populated fine. The TabViews all setup and I have added a custom class to the main TabView controller which can take the ID (required to interrogate service and return further data) and Customer Name. I have also added a UIViewController for the first tab in which I need to get the ID value.

I can't seem to get hold of the ID or Company Name that is passed. I have tried importing the .h file of the UITabView. I know the UITabView .h file is being populated with the values as in the .m file I am using the Customer Name to update the title of the Navigation Bar. However, whenever I breakpoint on line that gets the ID in the .m file for the individual tab, it always returns nil.

I am using the following code to try and get this value:

companyTabController *headerData = [companyTabController alloc];
_companyName_lbl.text = headerData.companyName; 
_companyID_lbl.text = headerData.ID;

I have tried several variations of the above and all to no avail.

If your segueing you have to use the prepareForSegue:sender: method as such:

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
companyTabController *companyTC = [segue destinationViewController];
companyTC.companyName_lbl.text = headerData.companyName;
etc
}

if your not segueing you will have to instantiate it as such : 

- (void) didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *selectedCell = [self.tableView cellForRowAtIndexPath:indexPath];
companyTabController *companyTC = [self.storyboard instantiateViewControllerWithIdentifier:@"CopmanyTabController"];
companyTC.companyName_lbl.text = selectedCell.textLabel.text or = headerData.companyName;
[self.navigationController pushViewController:companyTC animated:YES];
}

From the code you posted, the headerData is a new instance. So the companyName and the ID will be nil unless you assign some value to them.

Since, you mentioned that you are able update the navigation bar title, try using the same object for fetching the values in this controller as well. (Maybe you can use a singleton object)

You can also use NSUserDefaults to save the data, I think that is the simplest way to save the data throughout the app.
