UISegmentedControl selector not working - ios

Question

I have a calls Called Modal that I am running the following code in.
- (void)createAccessoryView
{
CGRect frame = CGRectMake(0.0, self.frame.size.height, self.frame.size.width, 44.0);
fieldAccessoryView = [[UIToolbar alloc] initWithFrame:frame];
fieldAccessoryView.barStyle = UIBarStyleBlackOpaque;
fieldAccessoryView.tag = 200;
[fieldAccessoryView setBarStyle:UIBarStyleBlack];
UIBarButtonItem *spaceButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:#selector(done:)];
UISegmentedControl* segmentedControl = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:NSLocalizedString(#"Previous", #""), NSLocalizedString(#"Next", #""), nil]];
[segmentedControl addTarget:self action:#selector(segmentAction:) forControlEvents:UIControlEventValueChanged];
segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
[segmentedControl setMomentary:YES];
UIBarButtonItem *segmentButton = [[UIBarButtonItem alloc] initWithCustomView:segmentedControl];
[fieldAccessoryView setItems:[NSArray arrayWithObjects:segmentButton, spaceButton, doneButton, nil] animated:NO];
}
-(void)segmentAction:(id)selector
{
}
I then create a class that extends Modal and has a few UITextFields. Clicking on a text field brings up the keyboard as expected. Once the keyboard is launched I see the previous / next and done buttons. Clicking done throws and error and doesn't use the segmentAction method as it should. Not really sure why.
here is the stack trace I get after clicking the done button

Answer 1

The important part of the error is this:
[NotesModal done:]: unrecognized selector
Hence, it's crashing because it doesn't recognize the method done:.
Make sure that you actually have a done: method, such as this:
-(void)done:(id)sender
{
// whatever it does here...
}
Note -(void)done and -(void)done:(id)sender are not the same.

Answer 2

this code
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone
target:self
action:#selector(done:)];
needs a method
-(void)done:(id)selector
{
//…
}
either provide it or change the UIBarButtonItem to
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone
target:self
action:#selector(segmentAction:)];

Answer 3

Please check if your done method has any parameter.
It needs to be something like:
-(void)done:(id)selector
{
[self dismissModalViewController];
}
