Setting the title of a dynamic view from a table view - ios

Question

I'm using a combination of SWRevealViewController, A ContentViewController and A NavigationViewController (Navigation).
The storyboard is as follows:
On TableViewCell click I can get the navigation text. What I want to be able to do is to pass this information back into itself. Setting the title of the ContentViewController to the selected cell and loading other desired data.
How can I fulfil this functionality?
Here is my latest code within my NavigationViewController.m file:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
BOOL isChild = currentExpandedIndex > -1 && indexPath.row > currentExpandedIndex && indexPath.row <= currentExpandedIndex + [[subItems objectAtIndex:currentExpandedIndex] count];
UITableViewCell *selectedCell = [self.tableView cellForRowAtIndexPath:indexPath];
if (isChild) {
NSString *cellText = selectedCell.detailTextLabel.text;
NSLog(#"%# tapped",cellText);
return;
}
else{
NSString *cellText = selectedCell.textLabel.text;
NSLog(#"%# tapped",cellText);
if([cellText isEqualToString:#"Sign Out"]){
[self performSegueWithIdentifier:#"goToHome" sender:self];
}
else if ([cellText isEqualToString:#"Sign In"]){
[self performSegueWithIdentifier:#"goToHome" sender:self];
}
else if ([cellText isEqualToString:#"Festival Map"]){
[self performSegueWithIdentifier:#"festivalMap" sender:self];
}
}
[self.tableView beginUpdates];
if (currentExpandedIndex == indexPath.row) {
[self collapseSubItemsAtIndex:currentExpandedIndex];
currentExpandedIndex = -1;
}
else {
BOOL shouldCollapse = currentExpandedIndex > -1;
if (shouldCollapse) {
[self collapseSubItemsAtIndex:currentExpandedIndex];
}
currentExpandedIndex = (shouldCollapse && indexPath.row > currentExpandedIndex) ? indexPath.row - [[subItems objectAtIndex:currentExpandedIndex] count] : indexPath.row;
[self expandItemAtIndex:currentExpandedIndex];
}
[self.tableView endUpdates];
}
- (void)expandItemAtIndex:(int)index {
NSMutableArray *indexPaths = [NSMutableArray new];
NSArray *currentSubItems = [subItems objectAtIndex:index];
int insertPos = index + 1;
for (int i = 0; i < [currentSubItems count]; i++) {
[indexPaths addObject:[NSIndexPath indexPathForRow:insertPos++ inSection:0]];
}
[self.tableView insertRowsAtIndexPaths:indexPaths withRowAnimation:UITableViewRowAnimationFade];
}
- (void)collapseSubItemsAtIndex:(int)index {
NSMutableArray *indexPaths = [NSMutableArray new];
for (int i = index + 1; i <= index + [[subItems objectAtIndex:index] count]; i++) {
[indexPaths addObject:[NSIndexPath indexPathForRow:i inSection:0]];
}
[self.tableView deleteRowsAtIndexPaths:indexPaths withRowAnimation:UITableViewRowAnimationFade];
}
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if([[segue identifier] isEqualToString:#"festivalMap"]){
NSLog(#"TEST");
NSString * title = #"CHANGE";
ViewController * view = [segue destinationViewController];
view.navigationItem.title = title;
}
}
And here is the code for my ContentViewController.m file:
#import "ContentViewController.h"
#import "SWRevealViewController.h"
#import "Function.h"
#interface ContentViewController ()
#end
#implementation ContentViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
_barButton.target = self.revealViewController;
_barButton.action = #selector(revealToggle:);
[self.view addGestureRecognizer:self.revealViewController.panGestureRecognizer];
}
#end
Thanks

You can Try this:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if([segue.identifier isEqualToString:#"yoursegue"]){
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
UITableViewCell *selectedCell = [self.tableView cellForRowAtIndexPath:indexPath];
ContentViewController*contentView = (ContentViewController*)segue.destinationViewController;
contentView.cellText = selectedCell.textLabel.text;
NSLog(#"cellText = %#",selectedCell.textLabel.text;);
}
}
However, it is not good practice to access value from the user interface or build the logic around it, instead you should be using the datasource.This violate MVC principles.
