Select a View-based Application give the name as Button & add a new file give the name SecondViewController,
Write the following code in Button.m
Import your SecondViewController , By writing statement
#import "SecondViewController.h"
- (void)viewDidLoad {
    [super viewDidLoad];
          UIButton *btnObj = [UIButton buttonWithType:UIButtonTypeRoundedRect];
          btnObj.frame = CGRectMake(40, 40, 70, 50);
          [btnObj setTitle:@"CLICK" forState:UIControlStateNormal];
          [btnObj addTarget:self action:@selector(nextView) forControlEvents:UIControlEventTouchUpInside];
          [self.view addSubview:btnObj];
          //[btnObj release];
-(void)nextView{
          SecondViewController *secObj = [[SecondViewController alloc]initWithNibName:@"SecondViewController" bundle:nil];
          [self presentModalViewController:secObj animated:YES];
