Answer 1

Try this ::

In .h file

@property(nonatomic, retain) IBOutlet UIScrollView *scr;
@property(nonatomic, retain) IBOutlet UITextField *txt;
@property(nonatomic, retain) IBOutlet UITextView *txtVw;
@property(nonatomic, retain) IBOutlet UIButton *btn;

-(IBAction)click:(id)sender;

In .m file

int cnt;

float x = 0.0, y = 0.0, w = 0.0, h = 0.0;

- (void)viewDidLoad
{
    [super viewDidLoad];

    scr.delegate = self;
    scr.contentSize = CGSizeMake(0, 400);

    cnt = 0;
}

-(IBAction)click:(id)sender
{
    if (cnt == 0) {
       x=txt.frame.origin.x;
       y=txt.frame.origin.y + 50;//get y from previous textField and add 10 or so in it.
       w=txt.frame.size.width;
       h=txt.frame.size.height;
    }
    else
    {
       y+=50;
    }

    UITextField *textField=[[UITextField alloc] initWithFrame:CGRectMake(x, y, w, h)];
    textField.borderStyle = UITextBorderStyleRoundedRect;
    textField.placeholder = @"Enter User Name or Email";

    [scr addSubview:textField];

    [btn setFrame:CGRectMake(248, y, 30, 30)];

    float y1 = y + 100;
    [txtVw setFrame:CGRectMake(orign_x, y1, origin_w, origin_h)];

    cnt++;
}

Hope, it'll definately help you.

Thanks.
