Question

I am new to Ios programming i want to display the data from master view controller into the detail view controller, i am using the master detail template from xcode. the detail array is working it shows the detail in label, how ever i want to display the title as well which is stored in _objects array,
here is my code
#import "MasterViewController.h"
#import "DetailViewController.h"
#interface MasterViewController () {
NSMutableArray *_detailObjects;
NSMutableArray *_thumbnailImage;
}
#end
#implementation MasterViewController
#synthesize _objects;
- (void)awakeFromNib
{
[super awakeFromNib];
}
- (void)viewDidLoad
{
[super viewDidLoad];
self.navigationItem.title= #"Zodiac List";
_objects = [[NSMutableArray alloc] initWithObjects:
#"value 1",
#"value 2",
#"value 3",
#"value 4",
#"value 5",
,nil];
_detailObjects = [[NSMutableArray alloc] initWithObjects:
#"detail of value 1",
#"detail of value 2",
#"detail of value 3",
#"detail of value 4",
#"detail of value 5",
, nil];
}

[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return _objects.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"Cell" forIndexPath:indexPath];
NSDate *object = _objects[indexPath.row];
cell.textLabel.text = [object description];
return cell;
}
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([[segue identifier] isEqualToString:#"showDetail"]) {
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
NSMutableArray *object = _detailObjects[indexPath.row];
[[segue destinationViewController] setDetailItem:object];
}
}
#end
the detail is working fine how ever i want to display the value 1, value 2,value 2 in a label as well..
here is my detail view controller code..
#property (strong, nonatomic) id detailItem;
#property (strong, nonatomic) id detailItemTitle;
#property (weak, nonatomic) IBOutlet UILabel *detailDescriptionLabel;
#property (weak, nonatomic) IBOutlet UILabel *zodiacNameLabel;
here is .m file code
#import "DetailViewController.h"
#import "MasterViewController.h"
#interface DetailViewController ()
- (void)configureView;
#end
#implementation DetailViewController
#synthesize zodiacNameLabel;
#pragma mark - Managing the detail item
- (void)setDetailItem:(id)newDetailItem
{
if (_detailItem != newDetailItem) {
_detailItem = newDetailItem;
// Update the view.
[self configureView];
}
}
-(void) setDetailItemTitle:(id)detailItemTitle{
if (_detailItemTitle !=detailItemTitle) {
_detailItemTitle = detailItemTitle;
[self configureView];
}
}
- (void)configureView
{
// Update the user interface for the detail item.
if (self.detailItem) {
self.detailDescriptionLabel.text = [self.detailItem description];
// self.zodiacNameLabel.text = [self.]
MasterViewController *master = [[MasterViewController alloc] init];
zodiacNameLabel.text = [master._objects objectAtIndex:0];
}
// if (self.detailItemTitle) {
// self.zodiacNameLabel.text = [self.detailItem description];
// }
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
[self configureView];
// MasterViewController *master = [[MasterViewController alloc] init];
// zodiacNameLabel.text = [master._objects objectAtIndex:0];
// MasterViewController *master = [[MasterViewController alloc]init];
// zodiacNameLabel.text = [master._objects objectAtIndex:0]; // you can get first element of an array
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#end

Answer 1

Implement delegate method of tableview which is in your masterviewcontroller and then inside that push your data whatever you want to display in masterviewcontroller like that:-
Assuming that below delegate is in your masterViewController
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
_yourController = [[yourController alloc] initWithNibName:#"yourController" bundle:[NSBundle mainBundle]];
[self.navigationController pushViewController:_yourController animated:YES];
}
Now this will alloc, initialize and load your nib into detailviewcontroller and if you want to send message from master to detail then declare property method in detailviewcontroller and just pass it from above like that below:-
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
_yourDetailController = [[yourDetailController alloc] initWithNibName:#"yourDetailController" bundle:[NSBundle mainBundle]];
[_yourDetailController setTempString:#"test"]; //Assuming that tempString is declared in yourDetailController class
[self.navigationController pushViewController:_yourDetailController animated:YES];
}

Answer 2

Make an array that is "tmpArray" in detailViewController and then you can copied _objects array in to tmpArray. like this
MastrerViewController.m
DetailViewController *detail = [[DetailViewController alloc]init];
detail.tmpArray = [[NSMutableArray alloc] initWithArray:_objects];
DetailViewController.h
#property (nonatomic,retain) NSMutableArray *tmpArray;
