Loading problem of NIB file from TabViewController in iPhone

I have a UITableViewController (MyViewController.xib). This is showing 3 rows with their title. I have 3 new xib file for each row title.On each row selection I want to load XIB file. I am getting the place when I am clicking on RowIndex Selection. But when i am trying to load NIB file nothing is happening. I mean nither program is being crashed nor NIB file is being load.

I am defining my interface declaration here.

 #import <UIKit/UIKit.h>

 #import "HistoryShow.h"

@interface MyViewController : UITableViewController {

    NSArray *tableList;

   IBOutlet HistoryShow *historyController;



}

@property (nonatomic,retain) NSArray *tableList;

@property (nonatomic,retain) IBOutlet HistoryShow 开发者_Go百科*historyController;

@end

My implementation details are below.

 -(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {


    NSString *str = [NSString stringWithFormat:@"%@",[tableList objectAtIndex:indexPath.row]]; //typecasting

     if([@"History" isEqual:str])
    {
       NSLog(@"!!!!!!!!!!!!!!!");   

     HistoryShow *detailViewController = [[[HistoryShow alloc]initWithNibName:@"HistoryShow" bundle:nil]autorelease];

 [historyController release]; 

    } 
}

This is prining "!!!!!!" on console but next "HistoryShow.xib" is not being load.

What is the exact problem ? Thanks in advance.

You have to add the view to your present view using addSubview: or push the viewController using a navigationController to see the view.

Something like this

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {


NSString *str = [NSString stringWithFormat:@"%@",[tableList objectAtIndex:indexPath.row]]; //typecasting
if([@"History" isEqual:str])
{
NSLog(@"!!!!!!!!!!!!!!!");   
HistoryShow *detailViewController = [[HistoryShow alloc]initWithNibName:@"HistoryShow" bundle:nil];
[self.navigationController pushViewController:detailViewController animated:YES]; //  if you have a navigation controller
[detailViewController release]; 
} 
}

You are instantiating detailViewController, but you aren't doing anything with it.

Try adding this after the alloc of detailViewController:

[self presentModalViewController:detailViewController animated:YES];
