Hi,,

The basics of the IOS.

When we create an empty project

ViewController1 *obj = [[ViewController1 alloc]init];

UINavigationController *navobj = [[UINavigationController alloc]initWithRootViewController:obj];

[self.window setRootViewController:navobj];

[self.window makeKeyAndVisible];

return YES;

TO navigate other class

- (IBAction)buttontonavigate:(id)sender {

ViewController2 *obj2 = [[ViewController2 alloc]init];

[self.navigationController pushViewController:obj2 animated:YES];

}
