How to enable next and prev buttons on simple form - iphone

Question

So I'm looking for a way to create some kind of form in my iPhone. I add for example 3 textfields and when I click on first one and write something in I want to be able to press next and it would take me to the next textfield.

I want to do something like if you fill in a web form.

Answer 1

When the user clicks Next, you can use,
[nextTextFieldAlong becomeFirstResponder];
...to move the cursor to the next field.

Answer 2

First you have to set tags for your fields (1-3) then set an accsesory view in your textfields like this
[messageView setInputAccessoryView:[self createAccesoryView]];
You can use a method like this to generate the accesory view (this was take from apple documents) :
-(UIView*)createAccesoryView{
UIToolbar *toolbar = [[[UIToolbar alloc] init] autorelease];
[toolbar setBarStyle:UIBarStyleDefault];
[toolbar sizeToFit];
UISegmentedControl *segmentControl = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:#"Previous", #"Next", nil]];
[segmentControl setSegmentedControlStyle:UISegmentedControlStyleBar];
[segmentControl addTarget:self action:#selector(selectNextPrevious:) forControlEvents:UIControlEventValueChanged];
UIBarButtonItem *select = [[UIBarButtonItem alloc] initWithCustomView:segmentControl];
UIBarButtonItem *flex = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
UIBarButtonItem *done = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:#selector(doneTyping)];
[toolbar setItems:[NSArray arrayWithObjects:select, flex, done, nil]];
return toolbar;
}
Then in selectNextPrevious
-(void)selectNextPrevious:(id)sender{
if ([(UISegmentedControl*)sender selectedSegmentIndex]==0) {
if (activeField.tag>1) {
[[self.view viewWithTag:activeField.tag-1] becomeFirstResponder];
}
else {
if (activeField.tag<numberOfFields) {
[[self.view viewWithTag:activeField.tag+1] becomeFirstResponder];
}
}
}
