resignFirstResponder UITextView

Question

I am using a UITEXTVIEW. I am trying to send a resignFirstResponder when the done button is pressed. I am not sure how to trigger the method containing the resignFirstResponder line.

I have set the UITextView's delegate to the File's Owner in Interface Builder. This is my viewcontroller's header and implementation file:

#import <Foundation/Foundation.h>
#import "Question.h"

@interface CommentQuestionViewController : UIViewController {
    Question *question;
    IBOutlet UILabel *questionTitle;
    IBOutlet UITextView *inputAnswer; //this is the textview
}

@property (nonatomic, retain) UILabel *questionTitle;
@property (nonatomic, retain) Question *question;
@property (nonatomic, retain) UITextView *inputAnswer;

- (void) addButton:(id)sender isLast:(BOOL)last;
- (void) setQuestionId:(NSString*)quId withTitle:(NSString*)quTitle number:(NSString*)quNum section:(NSString*)sId questionType:(NSString*)qt;

@end


#import "CommentQuestionViewController.h"


@implementation CommentQuestionViewController

@synthesize questionTitle, question, inputAnswer;

- (void) addButton:(id)delegate isLast:(BOOL)last{
    UIBarButtonItem *anotherButton;
    anotherButton = [[UIBarButtonItem alloc] initWithTitle:@"Done" style:UIBarButtonItemStylePlain target:delegate action:@selector(finishQuestionnaire:)];     
    self.navigationItem.rightBarButtonItem = anotherButton;
    [anotherButton release];
}

-(void)viewDidLoad{  
    //self.questionTitle.text = question.qTitle;
    [[self questionTitle] setText:[question qTitle]];
    [super viewDidLoad];
    NSString *str = [NSString stringWithFormat:@"Question %@", [question qNumber]];
    //self.title = str;
    [self setTitle:str];
    [str release];
}

-(void) setQuestionId:(NSString*)quId withTitle:(NSString*)quTitle number:(NSString*)quNum section:(NSString*)sId questionType:(NSString*)qt{   
    question = [[Question alloc]init];
    [question setQId:quId];
    [question setQTitle:quTitle];
    [question setQNumber:quNum];
    [question setSectionId:sId];
    [question setQType:qt];
}

- (void) viewWillAppear:(BOOL)animated{
    self.navigationItem.hidesBackButton = YES;
}


- (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) textViewDidEndEditing:(UITextView*)textView{
    [textView resignFirstResponder];
}

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

- (void)dealloc {
    [inputAnswer release];
    [questionTitle release];
    [question release];
    [super dealloc];
}

You can try this:

–(BOOL)textView:(UITextView*)textView shouldChangeCharactersInRange:(NSRange)range replacementText:(NSString*)text {
    if ([text isEqualToString:@"\n"]) {
        [textView resignFirstResponder];
        return NO;
    }
    else
        return YES;
}

Of course, you won't be able to type actual carriage returns if you do this.
