i have tried many ways and i finaly realized the right method, but it works only when under view did load method objects have only one description but if it hase something like thise
gazel = [[NSMutableArray alloc] init];
Data *data = [[Data alloc] init];
data.title = #"<էրեբունի> Օդանավակայան";
data.subtitle = #"Հարաֆ Արևմտյան Թաղամաս";
data.photo = 1;
[gazel addObject:data];
its not working

custom tableview cell is not refreshing

This is my custom table view cell, I want to change those values in every 1 minute (values will load from server). I have already set an Nstimer and tried to reload the tableview. Data in my array is changing fine, but value in the uitableviewcell is not changing.
Code:

}

Why don't you try
[self.tableView reloadData];
instead of
UITableView *tv = (UITableView *)self.view;
[tv reloadData];
Only if your super class is UITableViewController.If not then make an outlet for tableView and reload table through it.
have you used this 'setNeedsDisplay' as
[cell.data11 setNeedsDisplay] if cellForRow is calling.
Please change below code :
/* TwoTableViewsViewController.m */
- (void)viewDidLoad {
[super viewDidLoad];
if (firstController == nil) {
firstController = [[FirstTVContoller alloc] init];
}
if (secondController == nil) {

}
[firstTable setDataSource:firstController];
[secondTable setDataSource:secondController];
[firstTable setDelegate:firstController];
[secondTable setDelegate:secondController];
firstController.view = firstController.tableView;
secondController.view = secondController.tableView;
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(reloadData:) name:#"ReloadFirstTable" object:nil];
}

{

}
Please use NSNotificationCenter to reload Data.
I fixed the issue. Forgot to reload UITableview object in viewcontroller. I removed the NStimer from Tableviewcontroller.m and placed it in the Viewcontroller.m.
The changed code:

-(void) loadView

defaults=[NSUserDefaults standardUserDefaults];
items=[NSArray arrayWithObjects:#" data1",#" data2 ", nil];
usercount=[NSArray arrayWithObjects:

**// removed the nstimer from here.**

UITableView is revealed only after it is scrolled upwards

I have a storyboard with a UIView and a UITableView in it. The UITableView has custom cells (UITableViewCell with xib).
When I run the app, only the first row of the table is shown, the rest of the table is hidden.
The rows are not seen on the screen, but they respond to user interaction as expected.
The rest of the cells are revealed only after the table is scrolled upwards.
What could be the problem?
Here is the code for UIView with the table:
#implementation EldersTableViewController
#synthesize items;
#synthesize tableView;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
EldersDataHendler *edh = [[EldersDataHendler alloc]init];
NSMutableArray *itemsFromPList = [edh dataForTableFrom:[NSDictionary dictionaryWithContentsOfFile:[[NSBundle mainBundle] pathForResource:#"eldersData" ofType:#"plist"]]];
self.items = itemsFromPList;
[edh release];
edh=nil;

for (id obj in topObjects){
if ([obj isKindOfClass:[EldersItemCell class]]){
cell = (EldersItemCell*)obj;
break;
}
}

[cell setObject:cellInfo];
return cell;
}

Thanks in advance,

1st just create an object class for your cell design,then import it in your .m file.then try like this and connect the table view delegate and data source properly
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Displayfriendscell";
Displayfriendscell *cell = (Displayfriendscell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[Displayfriendscell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
}
// Configure the cell...
[[cell viewWithTag:121] removeFromSuperview];
[[cell viewWithTag:151] removeFromSuperview];
friend *user = [sortedFriendsArray objectAtIndex:indexPath.row];
cell.accessoryType = UITableViewCellAccessoryNone;
cell.selectionStyle = UITableViewCellSelectionStyleNone;
//cell.nameLabel.text = user.contactNAame;
cell.nameLabel.text = user.friendName;
//cell.nameLabel.text =[[sortedFriendsArray objectAtIndex:indexPath.row] objectForKey:#"name"];
//user.friendName=[[sortedFriendsArray objectAtIndex:indexPath.row] objectForKey:#"name"];
NSLog(#"name is%#",cell.nameLabel.text);
return cell;
}
Problem solved! Thanks a lot dear arooaroo. There was something with the custom cell with the xib. So I've created a custom Table View Cell programmatically. Here is a nice tutorial

Usually i write a method in the controller B like:
-(voi)initVCwithString:(NSString*)_string andSomeObject:(NSObject *)_obj;
(so the controller B must have 2 ivar, a string and an object, that you have to set in this method)
then call this in your didSelectRowAtIndexPath: from the controller A
...
B _vcB=//alloc..init..etc
[_vcB initVCwithString:yourCell.textLabel.text andSomeObject:someObj];
[self.navigationController pushViewController:_vcB animated:YES];
[_vcB release];
Then in cellForRowAtIndexPath of B set cell.detailTextLabel.text=yourStringIvar;
Hope this helps.
Basically there are two possibilities that seems to be suitable. You can write a custom delegate method which pass the value to the A controller, or you can make a notification via notification centre, which can then assign the value to the A controller by catching the notification which will be triggered by picking a cell in the controller B.

Select certain row in one of the selections in a table view

I create a table with two sections. Each section has four cells.I want to push to a new view by navigation controller when a certain cell is pressed by user.
However there are two sections. I don't know how to distinguish the cell selected belongs to which section in

In

you should check indexPath.section value to determine the section of the selected cell.

You should have a view controller that contains your table view (it could even be a subclass of UITableViewController). I don't believe that UINavigationController is mean't to be subclassed as you have. If you want a navigation controller you should create an instance of CustomTableViewController, containing your tableview, and then use the initWithRootViewController: method of UINavigationController:
CustomTableViewController * ctvc = [[CustomTableViewController alloc] init];
UINavigationController * navigationController = [[UINavigationController alloc] initWithRootViewController:ctvc];
[ctvc release];
// Superview is where you want this added
// probably your window in app did finish launching
[superview addSubview:navigationController.view];
[navigationController release];
