Easy :

ClassA.h

@interface ClassA : NSObject {
   UITextField* textfield;
}

@property(nonatomic, retain) UITextField* textfield;

ClassB.h

@ClassA;
@interface ClassB : NSObject {
   ClassA* refClassA;
   UITextField* textfield;
}

@property(nonatomic, retain)ClassA* refClassA;  // you can also use assign instead of retain if you masterize the concept
@property(nonatomic, retain)UITextField* textfield;

ClassA.m

@synthesize textfield;

- (void) somefunction {
     self.textfield.text=@"3";
}


// and somewhere when creating ClassB
yourClassBObject.refClassA = self;

ClassB.m

#import "ClassA.h"

@synthesize refClassA;
@synthesize textfield;

- (void) somefunction {
     self.textfield.text = self.refClassA.textfield.text;
}

You can set the value of text field in delegate variable by :

appDelegate.textValueVariable = textfieldA.text ;

Now You can access the delegate variable from ClassB by : (write the below code in ClassB's viewDidLoad or viewWillAppear)

textfieldB.text = appDelegate.textValueVariable ;

Take the TextfieldA value into a variable and then push the class to the another class and then with the class send your value and in the another class create a same type of variable and assign that value of the variable to the textfield similar like this--

Class A {
textfieldA.text=3;
int x;

anotherViewController *subControllr=[[anotherViewController alloc] initWithNibName:@"anotherViewController" bundle:nil];
    [subControllr setY:x];
    UINavigationController *controller =[[UINavigationController alloc] initWithRootViewController:subControllr];
    controller.navigationBar.barStyle = UIBarStyleBlackOpaque ;
    [subControllr setModalTransitionStyle:UIModalTransitionStyleFlipHorizontal];
    [[self navigationController] presentModalViewController:controller animated:YES];
    [subControllr release];
    [controller release];
}

Now Class B{ //create the same name variable as setY for passing the value

int y;
textfieldB.text=y;
}
