Please give the suggestion of these code
appdelegate.h
#import <UIKit/UIKit.h>
#import "MainViewController.h"
#interface MainAppDelegate : UIResponder <UIApplicationDelegate>
{
UINavigationController *navigationController;
}
#property (strong, nonatomic) UIWindow *window;
#property (nonatomic, retain) UINavigationController *navigationController;
#property (nonatomic, retain) MainViewController *MainviewController;
appdelegate.m
#import "MainAppDelegate.h"
#import "MainViewController.h"
#implementation MainAppDelegate
#synthesize navigationController, MainviewController;
#synthesize matri;
-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
matri=#"";
// Override point for customization after application launch.
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.MainviewController = [[MainViewController alloc] initWithNibName:#"MainViewController" bundle:nil];
self.navigationController = [[UINavigationController alloc] init];
self.window.rootViewController = self.navigationController;
[self.navigationController pushViewController:self.MainviewController animated:YES];
[self.navigationController setNavigationBarHidden:YES animated:NO];
[self.window makeKeyAndVisible];
return YES;
} //plaese provide detail of code
mainviewcontroller.h
#import <UIKit/UIKit.h>

mainviewcontroller.m

#end
#implementation MainViewController
{

}
//#synthesize pun;
- (void)viewDidLoad
{

tableData = [NSArray arrayWithObjects:#"1",#"2",#"3",#"4", nil];
NSLog(#"tabledata : %#", tableData);
// Do any additional setup after loading the view, typically from a nib.
}
-(NSInteger) tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
NSLog(#"tabledata : %#", tableData);
return [tableData count];
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

if (cell == nil)

i dont understand how to call secondview from first view help me out
the hole code file are for creating simple table view and to call secviewcontroller
can anyone help me to provide code how to call secview object and how to use in mainview controller
and i also created nsmutablearray with newarray object and synthesize it
can any one understand this code and give the brief description to that code and suggest me to what i miss sothat i can check this and call secviewcontroller from mainviewcontroller.

Answer 1

use this code into app delegate.m file
YourviewController *loginVc = [[YourviewController alloc] initWithNibName:#"YourviewController" bundle:nil];
self.navigationController = [[UINavigationController alloc] initWithRootViewController:loginVc];
self.window.rootViewController = self.navigationController;
self.navigationController.navigationBarHidden =YES;
[self.window makeKeyAndVisible];

Answer 2

CHeck this:
-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
matri=#"";
// Override point for customization after application launch.
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.MainviewController = [[MainViewController alloc] initWithNibName:#"MainViewController" bundle:nil];
self.navigationController = [[UINavigationController alloc] initWithRootViewController:self.MainviewController]; //Embedding your navigationController in mainviewcontroller
self.window.rootViewController = self.navigationController;
[self.navigationController setNavigationBarHidden:YES animated:NO];
[self.window makeKeyAndVisible];
return YES;
}
And then in your mainViewCOntroller.m
#import"appdelegate.h"
And then in
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
SecViewController *SecView = [[SecViewController alloc] initWithNibName:#"SecViewController" bundle:nil];
SecView.newarray =[tableData objectAtIndex:indexPath.row];
AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
[delegate.navigationController pushViewController:SecView animated:YES ];
}

Answer 3

Do this one.
self.MainviewController = [[MainviewController alloc] initWithNibName:#"MainviewController" bundle:nil];
self.navigationController = [[UINavigationController alloc] initWithRootViewController:self.MainviewController];
self.window.rootViewController = self.navigationController;
self.navigationController.navigationBarHidden =YES;
[self.window makeKeyAndVisible];
