employeeDetailed = [[[EmployeeDetailedViewController alloc] initWithNibName:@"EmployeeDetailedViewController" bundle:nil] autorelease];
UINavigationController *navController = [[[UINavigationController alloc] initWithRootViewController:employeeDetailed] autorelease];
[employeeDetailed release];
[self.navigationController pushViewController:navController animated:YES];
I try this its saying bad access.[crash]
how to reslove this issue.
@ thanks in advance
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
// Set the view controller as the window's root view controller and display.
UINavigationController *navController = [[[UINavigationController alloc] initWithRootViewController:self.viewController] autorelease];
self.window.rootViewController = navController;
[self.window makeKeyAndVisible];
return YES;
}
employeeDetailed = [[[EmployeeDetailedViewController alloc] initWithNibName:@"EmployeeDetailedViewController" bundle:nil] autorelease];
[self. navigationController presentModalViewController: navController];
This will work for you try this.
You have autorelease set in the first line (alloc/init)
You are then explicitly releasing the view controller on line three.
You are therefore over-releasing this object and causing the crash.
You can remove the [employeeDetailed release] line and it will be fine.
You cannot add UINavigationController to existed navigation stack. Instead of you need to show new navigation controller modal like this:
employeeDetailed = [[[EmployeeDetailedViewController alloc] initWithNibName:@"EmployeeDetailedViewController" bundle:nil] autorelease];
UINavigationController *navController = [[[UINavigationController alloc] initWithRootViewController:employeeDetailed] autorelease];
[self presentModalViewController: navController];
The Best Way I found to present Navigation Controller in a specific part in your Application is like these:
MyViewController *myViewController = [[MyViewController alloc]initwithnibname :@"MyViewController"];
UINavigationController *myNavC = [[UINavigationController alloc]initWithRootViewController:myViewController];
Then in your myViewController.m use
[self.NavigationController pushViewController: XController animated:YES];
