Push the values to new ViewController when a cell is tapped

I have table view that populated with plist called "Htgg". I am trying to push the value to a new view called "DetailViewController".

This is the code:

#import "Glist.h"

#import "DetailViewController.h"

@implementation Glist
@synthesize htgg,detailViewController;


- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        self.title = NSLocalizedString(@"ofek", @"ofek");
    }
    return self;
}

- (void)viewDidLoad
{

    [super viewDidLoad];

    self.navigationItem.title = @"איך להוציא גימלים?";
    NSString *htggFile = [[NSBundle mainBundle]pathForResource:@"Htgg" ofType:@"plist"];
    htgg = [[NSDictionary alloc] initWithContentsOfFile: htggFile];

}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

#pragma mark - Table view data source

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    // Return the number of sections.
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    // Return the number of rows in the section.
    return [htgg count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
        cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
    }


    id keys = [htgg allKeys];


    //Get all the keys in the first dictionary (the keys are: "good", "funny", "New - Item 3")
    //This is an array, so you can do this: array[0] (in C#)

    //Here we tell the tableview cell. to put in the text - [keys objectsAtIndex:indexPath.row]; if the row is 0, we will get: "good", if 1, we will get "funny"
    cell.textLabel.text = [keys objectAtIndex:indexPath.row];


    return cell;
}

- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath
{
    // Return NO if you do not want the specified item to be editable.
    return NO;
}

#pragma mark - Table view delegate

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    DetailViewController *showPickedSolution = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:[NSBundle mainBundle]];
    [self.navigationController pushViewController:showPickedSolution animated:YES];


    [tableView deselectRowAtIndexPath:indexPath animated:YES];
}
@end

The code works perfect but it doesn't push the value of the row( all the rows of plist are string type and above the there is 'Root').

I need your help to push the value to another view(DetailViewController).

To achieve this you can made an NSString property in class DetailViewController and set that property in didSelectRowAtIndexPath. Here is the code for your reference:

showPickedSolution.valueToBeSent = [htgg valueForKey:[[htgg allKeys] objectAtIndex:indexPath.row]];

You can use this valueToBeSent in your DetailViewController class.

make a property in your DetailViewController of the same type as of your data you want to push then use

DetailViewController *showPickedSolution = [[DetailViewController alloc]  
 initWithNibName:@"DetailViewController" bundle:[NSBundle mainBundle]];
 showPickedSolution.yourPropertName = [htgg objectAt:indexPath.Row];      

[self.navigationController pushViewController:showPickedSolution animated:YES];

you can now access the passed dat in your DetailViewController in your property.

Please check the syntax.

I have done this in two different way depending on the scenario:

1) Delegate, when I fill some values on a form that I want to pass back to the original screen.

2) Storyboard Segue, when I want to send some value(s) to a second screen.

I usually put all the values I want in an array to send the object and then at arrival I extract what I need.

Instead of explaining each way, I can refer you to Getting Started section of the iOS Dev Site.

I hope it help!
