Hey Veer, There is a slightly different approach that you should be taking here. Here is what I propose.

.h file code

#import <UIKit/UIKit.h>

    @interface trialViewController : UIViewController <UIActionSheetDelegate, UITextFieldDelegate> {

        UITextField *TextField;

    }

    -(void) CreateSlideOut;
    -(void) removePopUp;
    -(void) slidePopup;
    @end

.m code

#import "trialViewController.h"

@implementation trialViewController


CGRect backToOriginal;
UIView *popup;

- (void)viewDidLoad {

    [self CreateSlideOut];
    [self slidePopup];
    [super viewDidLoad];
}


-(void) CreateSlideOut
{

    CGRect frame=CGRectMake(0, CGRectGetMaxY(self.view.bounds), 320, 480);

    backToOriginal=frame;

    popup=[[UIView alloc]initWithFrame:frame];

    popup.backgroundColor = [UIColor orangeColor];

    [self.view addSubview:popup];

}


-(void) slidePopup
{

    UIButton *button=[UIButton buttonWithType:UIButtonTypeRoundedRect];
    button.frame=CGRectMake(60, 190, 200,40);
    button.backgroundColor=[UIColor clearColor];

    [button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];

    [button setTitle:@"Dismiss" forState:UIControlStateNormal];
    [button addTarget:self action:@selector(DismissClicked:) forControlEvents:UIControlEventTouchUpInside];

    TextField = [[UITextField alloc] initWithFrame:CGRectMake(20, 28, 280, 150)];
    TextField.delegate=self;
    TextField.autocorrectionType = UITextAutocorrectionTypeNo;
    [TextField setBackgroundColor:[UIColor clearColor]];
    [TextField setBorderStyle:UITextBorderStyleRoundedRect];

    [popup addSubview:TextField];
    [popup addSubview:button];

    CGRect frame=CGRectMake(0, 0, 320, 480);

    [UIView beginAnimations:nil context:nil];

    [popup setFrame:frame];

    [UIView commitAnimations];  


}

-(void) removePopUp

{   
    [UIView beginAnimations:nil context:nil];

    [popup setFrame:backToOriginal];

    [UIView commitAnimations];

    [TextField resignFirstResponder];
}

-(IBAction) DismissClicked : (id) sender
{

    [self removePopUp];
}

- (void)didReceiveMemoryWarning {
    // Releases the view if it doesn't have a superview.
    [super didReceiveMemoryWarning];

    // Release any cached data, images, etc that aren't in use.
}

- (void)viewDidUnload {
    // Release any retained subviews of the main view.
    // e.g. self.myOutlet = nil;
}

- (BOOL)textFieldShouldReturn:(UITextField *)textField {
    NSLog(@"in textFieldShouldReturn");
    [TextField resignFirstResponder];
    return YES;
}

- (void)dealloc {
    [super dealloc];
}

@end

Use it and change the background color of the slideout. If you want I can give a codes that customize your UIButtons and create Custom colors for you to be used. Cheers

Only key window receives keyboard notifications, so you have to add your textField into the key window.

UITextField *textField    = [[UITextField alloc] initWithFrame:CGRectMake(0, 28, 320, 150)];
// Configure your textField here:

UIWindow *appWindow = [UIApplication sharedApplication].keyWindow;
[appWindow addSubview:textField];
