need an advice with orientation change iphone - iphone

Question

my problem might be simple to some of you but i can't find a solution. I have a method where a create my views automatically (text fields, labels and text views). It's like a registration form. The problem is that when i change the screen to landscape mode, i want to change the views width. To do that i used [self.view removeFromSuperview] and created the views again. The problem is that the views won't get recreated with the landscape width. I can't use IB to autosize the views at orientation change. The views are created in viewDidLoad and removed and recreated in - (void) adjustViewsForOrientation:(UIInterfaceOrientation)orientation {} I don't know why they don't get recreated after being removed. If there was another solution that you could share with me i would appreciate it.
Here's how i create the views:
-(void)createViews:(int)width
{
for(int i = 0; i < numberOfTextfields; i++) {
textfieldPadding = textfieldPadding+40;//set some space between the text fields
labelPadding = labelPadding+40;//set some space between the labels
UITextField *field = [[UITextField alloc] initWithFrame:
CGRectMake(10,i*textfieldHeight+textfieldPadding+firstTextfieldHeight+10,width, textfieldHeight)];
field.autoresizingMask = UIViewAutoresizingFlexibleWidth;
//field.backgroundColor= [UIColor cyanColor];
field.placeholder = [labels objectAtIndex:i];
field.borderStyle=UITextBorderStyleRoundedRect;
field.returnKeyType = UIReturnKeyDone;
[field addTarget:self action:#selector(doneButton:)
forControlEvents:UIControlEventEditingDidEndOnExit];
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(10, i*labelHeight+firstLabelHeight+labelPadding-20, width, labelHeight)];
label.text = [labels objectAtIndex:i];
//label.backgroundColor = [UIColor brownColor];
[scrollView addSubview:field];
[scrollView addSubview:label];
[textfields addObject:field];
[labels addObject:label];
[field release];
[label release];
}
}
Here's where i wanted to remove them and recreate them:
- (void) adjustViewsForOrientation:(UIInterfaceOrientation)orientation
{
if (orientation == UIInterfaceOrientationLandscapeLeft || orientation == UIInterfaceOrientationLandscapeRight)
{
[self.view removeFromSuperview];
[self createViews:landscapeWidth];
}
else if(orientation == UIInterfaceOrientationPortrait || orientation == UIInterfaceOrientationPortraitUpsideDown)
{
[self.view removeFromSuperview];
[self createViews:portraitWidth];
}
}
Thanks in advance!

Instead of removing, resizing and then re-adding as you currently are why not just set the appropriate autoresizingMask (link) when you create the view initially?
UITextField *myTextField = [[UITextField alloc] initWithFrame:someRect];
// the following will automatically resize the width on orientation change
myTextField.autoresizingMask = UIViewAutoresizingFlexibleWidth;
[myView addSubview:myTextField];
[myTextField release];
