#interface tryViewController : UIViewController {
IBOutlet UITextField *textField;
}
#property(nonatomic,retain)IBOutlet UITextField *textField;
-(IBAction)submit;
#end
following is my page1 .m file:
#import "tryViewController.h"
#implementation tryViewController
#synthesize textField;
- (BOOL)textFieldShouldReturn:(UITextField *)theTextField {
[theTextField resignFirstResponder];
return YES;
}
- (void)viewDidUnload {
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (void)dealloc {
[super dealloc];
}
-(IBAction)submit
{
new *pg = [new alloc];
pg.str = textField.text;
[self .view addSubview:pg.view];
[self presentModalViewController:pg animated:YES];
}
#end
following is my page2 .h file:
#import <UIKit/UIKit.h>
#import "tryViewController.h"
#interface new : UIViewController {
IBOutlet UITextField *txtField;
NSString *str;
}
#property(nonatomic,retain)IBOutlet UITextField *txtField;
#property(nonatomic,retain)NSString *str;
-(IBAction)back;
#end
following is my page2 .m file:
#import "new.h"
#implementation new
#synthesize str;
- (void)viewDidLoad {
txtField.text = str;
[super viewDidLoad];
}
- (void)dealloc {
[super dealloc];
}
-(IBAction)back
{
}
#end

Your code is ... strange.
Try to use class name beginning with a capital letter with an human readable name.
Why do you use modal view controller instead of navigation controller?
Try this kind of code:
EditViewController.h
#import <UIKit/UIKit.h>
#import "ShowViewController.h"
#interface EditViewController : UIViewController {
IBOutlet UITextField *textField;
}
#property(nonatomic,retain)IBOutlet UITextField *textField;
-(IBAction)submit;
#end
EditViewController.m
#import "EditViewController.h"
#implementation EditViewController
#synthesize textField;
- (BOOL)textFieldShouldReturn:(UITextField *)theTextField {
[theTextField resignFirstResponder];
return YES;
}
- (void)viewDidUnload {
// Release any retained subviews of the main view.
self.textField = nil;
}
- (void)dealloc {
[super dealloc];
}
-(IBAction)submit {
ShowViewController *showViewController = [[ShowViewController alloc] initWithNibName:#"ShowViewController" bundle:nil];
showViewController.string = textField.text;
[self.navigationController pushViewController:showViewController animated:YES];
}
#end
ShowViewController.h
#import <UIKit/UIKit.h>
#interface new : ShowViewController {
}
#property(nonatomic,retain)IBOutlet UITextField *txtField;
#property(nonatomic,retain)NSString *string;
-(IBAction)back;
#end
ShowViewController.m
#import "ShowViewController.h"
#implementation ShowViewController
#synthesize string;
- (void)viewDidLoad {
[super viewDidLoad];
txtField.text = string;
}
- (void)dealloc {
[super dealloc];
}
-(IBAction)back {
[self.navigationController popViewControllerAnimated:YES];
}
#end
In your MainWindow.xib add a Navigation Controller (or create your project with the navigation controller wizard.
If you doesn't want a nab bar just add a
[navigationController setNavigationBarHidden:YES animated:NO];
in your application delegate.
